Solving Low Water Pressure: How Repiping with PEX Can Help

5 min read

If you're a homeowner dealing with low water pressure in your house, it can be an incredibly frustrating experience. Low or inconsistent water pressure makes everyday tasks like washing dishes and taking showers more difficult than they need to be. But the cause of this issue isn't always obvious – often, old plumbing systems such as galvanized steel and copper pipes are corroding away, leading to blockages that result in low water pressure. In this blog post we'll discuss what causes these issues and how repiping with PEX piping systems can help resolve them once and for all. Learn about the signs of low water pressure, why professional repiping services are necessary for homeowners experiencing these problems, and the benefits of using PEX plumbing.

Causes of Low Water Pressure in Your House

Low water pressure can be a nuisance and even a health hazard. It’s important to understand the causes of low water pressure in order to take the necessary steps to fix it.

Corrosion in Copper Pipes:

Copper pipes are susceptible to corrosion over time, leading to decreased flow rates and low water pressure. Corrosion is caused by acidic or alkaline solutions that eat away at the metal, reducing its thickness and creating pinhole leaks. This can lead to reduced flow rate as well as discolored or foul-smelling water from your faucets and showers.

Galvanized Steel Pipes:

Galvanized steel pipes were once popular for plumbing systems due their durability, but they are prone to rusting over time which can cause blockages that reduce water pressure. Rust particles created by these pipes will eventually clog up plumbing fixtures and other components of your plumbing system such as shower heads, faucet aerators, valves, etc., resulting in low flow rates and weak performance from your fixtures.

Polybutylene Pipes: 

Polybutylene pipes are one of the most common culprits of low water pressure in homes. These pipes are known to become brittle over time, leading to small pinhole leaks that ultimately cause slow or nonexistent water flow. If your home is equipped with this type of pipe, it’s important to identify and resolve any low-pressure issues as soon as possible. Most insurance companies will not issue new policies if polybutylene plumbing is discovered in the home making it necessary to repipe.

CPVC Pipes:

CPVC (Chlorinated Polyvinyl Chloride) pipes have become increasingly popular due to their affordability and ease of installation in comparison with copper piping systems. However, they are still susceptible to corrosion if exposed to certain chemicals such as chlorine bleach or sulfuric acid, which can weaken them over time and reduce the flow rate through the pipe walls resulting in low water pressure issues throughout your home's plumbing system.

Lead Pipes:

Lead pipes were once used extensively for plumbing purposes before being phased out due to its toxicity. However, many older homes still contain lead piping which has been known to cause serious health problems when ingested, according to the Centers for Disease Control (CDC). In addition, lead piping also corrodes easily leading to low flow rates through the pipe walls resulting in low pressure issues throughout your home's plumbing system.

The causes of low water pressure can vary greatly, from corrosion in copper pipes to galvanized pipes and beyond. To ensure your plumbing system is functioning optimally, it's important to identify the signs of low water pressure so you can take the necessary steps to remedy the issue.

Key Takeaway: Low water pressure can be caused by corrosion in copper, CPVC and lead pipes, rusting of older galvanized steel pipes, and pinhole leaks in polybutylene pipe. It's important to identify the source of the issue in order to fix it properly.

Signs of Low Water Pressure

Poor Flow:

Low flow from faucets and showers is one of the most common signs of low water pressure. If you notice that your shower or sink takes longer to fill up than usual, it could be a sign that there’s an issue with your plumbing system. Additionally, if you find yourself having to turn the tap all the way up just to get a trickle of water out, this can also indicate low water pressure.

Unusual noises:

Unusual noises coming from your plumbing system are another indication that something may be wrong with your water pipes. You might hear loud banging or gurgling sounds when running taps or flushing toilets which can signify air bubbles in the pipes due to insufficient pressure.

Rusty Colored Drinking Water:

Discolored water coming out of faucets and showers is yet another warning sign of inadequate water pressure. This could mean there is rust in the pipes caused by corrosion over time, leading to sediment buildup which restricts flow and causes discoloration in the water supply.

If you're experiencing any of the signs of low water pressure discussed above, it's time to consider a repiping solution. PEX piping systems offer increased flow rate and pressure, durability and longevity, as well as cost-effectiveness - all beneficial features for homeowners looking to improve their plumbing system's performance.

Benefits of Repiping with PEX Piping Systems

Cost-effective solution:

Repiping with PEX piping systems offers homeowners a cost-effective solution to improve their plumbing system's performance and efficiency. PEX piping is highly durable, resistant to corrosion, leaks, and cracks, making it an ideal choice for repiping projects. The increased flow rate and pressure that comes with using PEX pipes can make a huge difference in the overall performance of your plumbing system.

Increased Flow Rate:

The increased flow rate means more water will be available when you need it most. This can help reduce wait times for hot water at the shower or sink faucet as well as provide better pressure for washing machines and dishwashers. Additionally, since PEX pipes are less prone to corrosion than copper or galvanized steel pipes they last longer which helps save money on costly repairs down the road.


The durability of PEX piping systems is an important factor to consider when undergoing a repipe project. Unlike copper or galvanized steel pipes, which can corrode over time due to exposure from elements such as oxygen and chlorine found in tap water, PEX has been proven to withstand these conditions much better. This leads to fewer issues down the line like pinhole leaks or pipe bursts, which if left unchecked could cause extensive damage.

Homeowners can enjoy normal water pressure, increased durability and longevity of their plumbing system, as well as a cost-effective solution with repiping using PEX piping systems. Professional repiping services will ensure that the project is completed properly and efficiently, so that homeowners can reap the benefits of this upgrade for years to come.

Key Takeaway: PEX piping systems are a cost-effective solution to improve your home's water pressure and performance. They are highly durable, resistant to corrosion, leaks and cracks, have increased flow rate and pressure, last longer than copper or galvanized steel pipes and can withstand elements such as oxygen and chlorine found in tap water.

How much does it cost to repipe with PEX?

The cost of repiping with PEX will depend on the size and complexity of the job. Generally, it can range from a per “drop” price or a lump sum. A “drop” is a hot or cold line that feeds a fixture such as a sink or toilet. However, additional costs may be incurred if there are any complications such as accessing difficult areas, wall patching or replacing existing plumbing fixtures. Additionally, labor costs should also be taken into consideration when calculating the total cost of a repipe project. All in all, it is best to consult a qualified and licensed professional who can provide an accurate estimate based on your specific needs and requirements.

Why is PEX pipe superior over Copper Pipe?

PEX pipe offers several advantages over copper pipe when it comes to plumbing applications. Corrosion resistance is one of the primary benefits of using PEX pipe instead of copper. Copper can corrode over time, leading to leaks causing flooding and property damage. PEX pipes are made from a plastic material that is resistant to corrosion. Temperature resistance is another advantage that PEX has over copper. Copper pipes can expand and contract with changes in temperature, which can cause them to break or become damaged over time. PEX pipes are much more flexible and able to withstand extreme temperatures without breaking or becoming damaged.

Should I Repipe if I have older galvanized steel pipes?

YES! If your home has older galvanized steel pipes then it may be time for a whole house repipe solution in order to replace them with more modern materials such as PEX (cross-linked polyethylene) piping which is much more durable than traditional copper piping. A full house repipe will provide better water flow throughout the entire home while also reducing the risk of future leaks due to corrosion from age or wear-and-tear on the existing pipes.

Why is PEX pipe superior over CPVC pipe?

PEX piping is a popular choice for home construction projects due to its superior temperature resistance, chemical resistance, and longevity. It is constructed from cross-linked polyethylene which makes it more durable than CPVC pipe. PEX also requires fewer fittings than CPVC pipe which makes it easier to install. Due to its strong construction and chemical resistance properties, PEX piping has a much longer lifespan than CPVC pipes. The cross-linked polyethylene construction of PEX gives the material superior chemical resistance when compared with CPVC pipes. This means that PEX can withstand exposure to acids, alkalis, oils and other chemicals without corroding or degrading over time like some other materials would do in similar conditions. Also, PEX does not require glue or solvents to combine them like CPVC.

Why is PEX replacing my Polybutylene?

Research suggests that polybutylene pipes are too fragile to withstand common disinfectants found in the public water supply and will quickly become brittle and crack from the inside out. Over time, once enough mini fractures have formed in the pipe, it will wear out completely, rupture, causing a leak or flooding of a home. This is why no insurance carriers will no longer cover a home with Polybutylene piping. Homes can no longer be sold in many areas without removing the polybutylene and repiping the homes water supply making it a requirement to repipe a home.
