How a Plumber Fixes Sewer Line Problems
Plumber Aurora CO installs and repairs the pipes that carry water, gas, waste, and other materials to and from homes and businesses. Their work requires knowledge of blueprints and building codes to properly place and connect pipes, fixtures, and appliances.
Many plumbers are self-employed, which gives them flexibility in scheduling. However, they often must be available for emergency repairs.
Tree roots are drawn to the moisture and nutrients found in sewer lines, which makes them a common cause of clogs, damage, and structural failure. Understanding how and why root intrusion occurs is the first step in preventing costly repairs and maintaining a healthy sewage system.
Roots invade sewer lines by entering through small cracks, holes, or misaligned joints in the pipes. Over time, these roots can grow rapidly, blocking the line and causing serious plumbing issues for homeowners. It’s essential to inspect your sewer line for signs of root intrusion, including slow draining sinks and tubs, toilets that don’t flush properly, and a foul smell coming from your drains or around your property.
A recurrent clog that won’t go away with a plunger or chemical drain cleaner is another sign of a problem with invading roots. The continuous growth of these roots can eventually lead to a complete blockage, resulting in sewage back-ups, water usage increases, and inflated utility bills.
Over time, the constant pressure of growing roots can also cause structural damage to the pipes. This can lead to cracks, breaks, and collapse, which can affect the entire sewage line for an entire neighborhood or city.
Regular sewer maintenance can help prevent this from happening, and you should avoid planting trees or shrubs near your sewer line. If you do have a tree near your sewer line, consider hiring a professional to install a protective barrier to deter the spread of roots. Also, upgrading your current sewer line to plastic that is less susceptible to damage from roots can be an effective long-term solution. If you’re unsure whether or not your sewer line is at risk from invasive tree roots, contact Harts Services to schedule a camera inspection today.
Sewer Line Damage

Damaged sewer lines can create a mess inside your home, putting you and your family at risk of disease and other health issues. Understanding the most common signs of sewer line damage can help you prevent costly repairs and keep your plumbing running smoothly.
If you notice that sewage is backing up into drain openings in your home, it’s time to call for professional help. A sewer leak can also cause significant structural problems in your home, including weakened walls and foundation cracks. A broken pipe can even lead to flooding and contaminated groundwater, which is very dangerous for your home and health.
Frequent clogs and blockages in your home are another clear sign of a failing sewer line. If your drains seem to clog quickly after you clean them, it’s likely because the sewer line is obstructed. If the problem keeps reoccurring, it’s best to call a plumber for a professional inspection.
A gurgling sound when you run your washing machine or toilet can also indicate a problem with the sewer line. These sounds are caused by air trapped in blocked pipes, which can’t flow properly through the system. Professionals use techniques like camera inspections to identify the root of the issue, then repair or replace the damaged section.
Traditional sewer line replacement can be expensive, and it requires extensive excavation work on your property. However, newer technologies like pipe lining and pipe bursting can minimize landscape disruption while reducing costs and installation time. The experts at Ben Franklin Plumbing can help you decide which solution is best for your situation and budget.
Leaking Pipes
Pipes are a vital part of your plumbing system, but they can get damaged for a number of reasons. One of the most common is corrosion, especially when they’re made of metal. Corrosion can eat through the pipe, causing it to leak.
A burst pipe can cause extensive water damage that requires a costly repair bill. The best way to prevent this is by having a plumber perform regular maintenance inspections. These will help to identify any potential problems before they become major issues.
When a pipe leaks, it can waste thousands of gallons of water and cause damage to your walls, floors and personal belongings. It’s important to find and address the leak as quickly as possible.
You can often spot a minor pipe leak by noticing damp patches on walls, floors or ceilings. You may also notice an increase in your water bill. A professional plumber can inspect your home’s pipes and fixtures to find the source of the leak and provide a permanent fix.
Some small leaks can be fixed with fiberglass tape or epoxy putting. You can also use adjustable pipe clamps to temporarily seal the leak until you can call a plumber. A professional can provide a permanent solution and ensure that the problem doesn’t return. A professional can also dry the affected area and check for further issues. Prevention is always the best approach when it comes to your plumbing system. Regular maintenance, including checking for signs of clogs, slow draining or high water pressure, can keep your pipes in good condition and avoid a costly plumbing emergency. You can also reduce the chances of leaks by having a professional install a pressure regulator on your main line and avoiding commercial-grade drain cleaners that can eat through pipes.
Leaks
The plumbing profession is all about separating clean water from harmful contaminants. That’s why plumbers are called on to build and repair long, traversing lines of pipes that transport freshwater, waste, and sewage throughout homes and businesses. Leaks in these systems are a major hazard that can lead to water damage, mold growth, and structural instability. The good news is that plumbers have a variety of tools at their disposal to detect and repair leaks as quickly and painlessly as possible.
When sewage backs up into toilets and drains, it’s a clear sign that something is wrong with the sewer line. Plumbers can help restore proper flow by chopping through the blockage, or they can install new parts to fix the break.
Homeowners can help prevent sewer problems by keeping an eye on what goes down the drains (wet wipes are notorious for causing clogs) and using non-caustic cleaning solutions in their bathrooms. They should also schedule regular professional plumbing maintenance services to keep their home’s drains flowing freely.
For serious issues, a plumber can use infrared cameras to scan for water temperature variations that indicate the presence of a leak. They can also employ line-tracing gear to map out subterranean piping routes and pinpoint the exact location of a leak. Once they have the location, they can plan the most effective course of action for repairing it without damaging other pipes or your property.
Drain Cleaning
Taking a proactive approach to drain maintenance is one of the best ways to avoid inconvenient and costly clogs. Clogged drains and sewer lines can lead to water waste, property damage and nasty, pervasive odors that diminish home comfort. Scheduled drain cleaning with your plumber helps prevent these issues and provides peace of mind that your plumbing system is working properly.
Using DIY solutions like a plunger or chemical drain cleaner can actually make clogs worse by causing pipe corrosion and harming the health of your plumbing system. Instead, a licensed plumber has the tools and expertise to dislodge even the most stubborn of blockages with minimal fuss.
For minor clogs, a plumber may use a drain snake or drain auger to break up and pull out the obstruction, allowing for normal drain flow. For more persistent clogs, hydrojetting may be needed. This process uses high-pressure water to blast through clogs and clear entire sections of your pipes, helping your plumbing system run smoothly for years to come.
A good plumber will be able to assess whether your clog is caused by hair, gunk or other debris, and offer you a solution that will work best for your home and budget. They will also be able to identify the root cause of your clog, which could indicate a larger problem with your plumbing system.
If you are looking for a long-term solution to your drain issues, consider switching from chemical cleaners to an eco-friendly enzyme-based drain cleaner. These products use natural ingredients to break down organic materials without corroding your pipes, and they are safe for the environment as well. By regularly using an enzyme drain cleaner, you can keep your plumbing in top shape and avoid the need for costly repairs down the road.
The Four Key Components of Refrigeration
Refrigeration is a process that cools enclosed spaces and substances. It operates by circulating refrigerant through the cooling system, which changes state to absorb and release heat. This cycle involves two different pressure areas: the evaporating low-pressure zone and the condensing high-pressure zone.
A refrigeration cycle is only effective if the food is cold when it goes into the fridge. This is why a fridge has special compartments to store items at the optimal temperature. Learn More About Us Here!
Refrigeration systems perform the seemingly magical task of transferring heat against its natural direction, keeping foods, spaces, and even industrial processes at the desired temperature. Behind the scenes, these cooling systems employ four key components: a compressor, condenser, expansion device, and evaporator. Each plays a unique role in the refrigeration cycle, but they all work together to transfer thermal energy. Let’s examine each of these parts to gain a better understanding of how refrigeration cycles function and how they can help with our daily lives and professional endeavors.
On call for refrigeration, the compressor (read more) sucks in superheated refrigerant vapor through its suction pipe and starts to compress it. As the compressor squeezes the vapor, its pressure and temperature increase while its specific volume decreases. This is what’s known as a phase change, as the vapor transitions from a liquid to a gas. After reaching its maximum pressure and temperature, the vapor moves into the condenser.
The condenser is a coil of tubing, typically copper, with metal fins and fans that remove the heat by dispersing it into the surrounding air. As the vapor from the evaporator moves through this coil, it absorbs the surrounding heat and changes back into a low-pressure liquid. The evaporator also serves to cool down the vapor.
Once the vapor from the condenser is in its low-pressure state, it is fed into an expansion valve, which reduces its pressure. This quick reduction induces the vapor to transform back into a low-pressure liquid-vapor mixture. The refrigerant then moves to the evaporator to repeat the cycle.
In the evaporator, the low-pressure liquid reverts into its vapor form once again and absorbs more heat from the surrounding environment. The evaporator is designed to amplify this process, by blowing hot air over the coil to speed up the rate of absorption and create more visible cooling effects. Once the evaporator is done absorbing heat, the liquid returns to the compressor for another round of compression.
Evaporator
The evaporator, or cooling coil, is where your refrigerator really gets cool. It takes the refrigerant that runs through copper tubing that’s connected to the outdoor unit and brings it into your home. The refrigerant passes through the evaporator’s coil and absorbs heat from the air that blows over it. The resulting condensation then flows into your drain pan and the cooling cycle begins again.
Immediately after the condenser, the refrigerant is sub-cooled and moves to its next step, the metering device. The metering device may be adaptive, such as a thermal expansion valve, or fixed like a capillary tube or an orifice. Its job is to “meter” the sub-cooled liquid into the evaporator. As it does, it creates a flash gas due to the drop in pressure as it enters the evaporator.
Once in the evaporator, it begins to evaporate or change state from liquid to vapor. This is accomplished by a combination of the heating medium (typically steam) and the refrigeration system’s low temperature. The evaporator comes in different types, including falling film, capillary, and flooded, each designed for a specific application.
In some systems, the evaporator is followed by a receiver. This is used to control the amount of refrigerant needed for the load. It also provides a storage tank for excess heat removal during normal operation.
Depending on the type of evaporator, it will have a large opening or multiple small ones. The larger opening allows the refrigerant to move into the cooler air as it vaporizes. This provides a very efficient method of heat transfer, as it’s like a heat pump in a sense.
It’s important to note that your evaporator coil must be kept clean. Even a fine layer of dust on the coil can prevent it from absorbing heat as effectively. This causes your refrigerator to use more energy and produce less cold, so it’s a good idea to keep the coil clear of dust and debris. In addition, be sure to maintain the proper airflow through your home’s vents and check the defrost timer and thermostat for problems.
Condenser
The cooling process starts in the evaporator, where cool air is blown across coils of low-pressure refrigerant gas. The vapor absorbs heat and rises, but because the air blowing over the coils is cooler than the vapor, it rejects that heat and cools down. This is why the evaporator is in your house, where you want the best cooling possible.
That cooled vapor then goes to the compressor. The compressor increases the pressure of the working gas, which causes the vapor to give up its heat in a different way by boiling into a hot liquid. The hot liquid then changes state again and is discharged into the condenser.
There are different types of condensers, with a few key differences in how they work. First, a condenser is usually made from metal, which helps to keep the vapor from losing its heat in the cold air blowing over it. Secondly, the condenser is typically designed with a fan in the top to pull cooling air into the unit and help the heat to release. A third important step is a metering device which controls how much vapor is released into the evaporator and helps the system maintain the desired temperature.
When the vapor enters the condenser, it will be at a higher temperature than either the air (in an air-cooled condenser) or water (in a water-cooled one). The difference in temperatures causes the vapor to give up its latent heat by changing back into a liquid, and because of the lowering of temperature, it will also experience a decrease in pressure.
Once the vapor changes state, it will pass through a heat exchanger, which may be either an unjacketed condenser tube or, more commonly, a flow-cooled condenser. The cooling system is a series of tubing that connects the various basic major components in the refrigeration cycle, with a suction line connecting the evaporator to the compressor, a hot gas or discharge line connecting the compressor to the condenser, and a liquid line from the condenser to the metering device (Thermal Expansion Valve).
The metering device ensures that only a certain amount of high-pressure liquid refrigerant is released into the evaporator. This is important to limit the loss of heat energy, which can cause other components in the cooling cycle to have to work harder.
Compressor
A compressor is the heart of any refrigeration system. It is considered to be the most important machine that can be used on any production site because it enables manufacturing to continue even when air pressure is lost. It is the compressor that makes or breaks the vapor compression refrigeration cycle. Without it, the cycle is not able to run and all of the work at that production site is suspended until the compressor is restored.
The compressor starts the refrigeration process by taking cold liquid refrigerant and absorbing it with heat from the evaporator at low temperature. This refrigerant is then pumped into the compressor where it is compressed and pressurised. It then goes into the condenser where it is cooled down to very low temperatures. As it cools down in the condenser it turns into a gas and absorbs heat from the cooling medium (usually air or water).
Once it is a hot gas, the refrigerant is pushed back into the compressor. It continues to be compressed in the compressor until it is at a high level of pressure and temperature. The compression of the refrigerant in the compressor is ideally isothermal which means that internal energy of the system is removed at the same rate as it is added by the mechanical energy of the compressor. However, due to mechanical limitations of the compressor it is not possible to achieve perfect isothermal compression.
There are five types of compressors commonly used in refrigeration systems. They include reciprocating, rotary, screw, centrifugal and scroll compressors.
Reciprocating compressors use pistons that move in a cylinder to pump up and compress the liquid. They are used in domestic and small commercial fridges.
Rotary compressors use a rotating blade inside a cage to trap and compress pockets of refrigerant. They are commonly found in industrial refrigerators.
Axial compressors are the largest and most powerful compressors. They have a cylindrical body with a hub and rim that contains impellers or disks. The rotating impellers spin to generate thrust and to increase velocity of the refrigerant. A diffuser section converts this velocity energy into pressure energy.
