4 of the Reasons to Watch Out for Pex Pipe

PEX (cross-linked polyethylene) piping has become a popular alternative to traditional copper and CPVC pipes in plumbing applications. It has several advantages, such as flexibility, ease of installation, and cost-effectiveness, making it a popular choice for many homeowners and plumbers. However, it is important to note that PEX is a relatively new material compared to copper and CPVC pipes, and its long-term durability and reliability are being questioned as more homeowners experience leaks in homes built as recently as 5 years prior to the first leaks. Here are some of the drawbacks of using PEX:

Longevity concerns: While PEX piping is relatively new compared to copper pipes, its long-term durability and reliability are still unknown. Some experts have concerns about the potential for PEX pipes to degrade over time and cause leaks or other problems.

Potential for chemical leaching: Some studies have suggested that PEX piping may leach chemicals into the water supply, which could be a concern for those with chemical sensitivities or other health concerns.

Reactions to chlorine: PEX piping can be sensitive to chlorine and other chemicals commonly used in water treatment, which can cause the piping to degrade and become brittle over time. This can lead to leaks and other issues, particularly in areas with high chlorine levels in the water supply.
Susceptibility to damage: PEX piping can be easily damaged by rodents or other animals that may chew through the piping, causing leaks and other issues.

Water pressure limitations: PEX piping has lower water pressure limitations compared to traditional water pipes, making it less suitable for certain high-pressure applications.
Reactions to chlorine: PEX piping can be sensitive to chlorine and other chemicals commonly used in water treatment, which can cause the piping to degrade and become brittle over time. This can lead to leaks and other issues, particularly in areas with high chlorine levels in the water supply.

Water Pressure in the Home: High & Low

Check the pressure in your home!

One of the important checks plumbers can make at your home is a water pressure test. The test usually involves hooking a standard water pressure guage (see below for a picture of one) onto an outside hose bibb (spiggot). 

High water pressure in a residence is a common problem. Many of the plumbing problems people notice in their house such as pipe noise, dripping faucets, running toilets, prematurly failing water heaters, and high water bills can be related to higher than optimal pressure. In Georgia, the potable water system in homes is not supposed to exceed 80 PSI. Water pressure in the municipal water mains is typically much higher than 80 PSI – sometimes well above 140 PSI. In order to reduce the pressure from the street pressure into the acceptable range, a Pressure Regulator Valve PRV is installed at the point where a water service line enters the home. If you have symptoms related to high pressure, the PRV in your home may not be doing it’s job. The recommended repair for this problem is a PRV is replacement. 

When customer is experienceing low water pressure, their fixtures (faucets, showers, etc) do not perform well. Washing, showering, cleaning etc are unpleasant, annoying or more difficult. One common cause of low water pressure in the home can be caused by a clogged or otherwise malfunctioning PRV.

A low pressure experience can also be cause be an undersized or crimped water line. In this case the pressure at an outside hosebibb (spiggot) may test normal. Uncovering a crimped/undersized line requires measuring the water pressure after fixtures are turned on in the house. The pressure reading taken when fixtures inside are in use is called the residual (or flow) pressure. 

An additional cause of low fixture can be malfunctioning or clogging at particular fixtures. If certain fixtures seem consistently lower pressure than others in the home, fixture problems may be the culprit. 

Rinnai Tankless Service Flush: Yes you can!

Same Day Water Heater Service

Rinnai tankless water heaters work perfectly as long as they are installed properly and undergo an occassional “flush out” to remove mineral scale from the inside of the heat exchanger. The tankless flush is a simple procedure and if you are a slightly mechanically-inclined handy-person, give it a shot. 

Polybutylene Kills a Home Price

People who are considering buying a home with polybutylene pipe should be aware of the major and invetable problems they will experience from owning a home with gray poly. I spoke with a home inspector down in Columbus Georgia who claims to tell his clients that there is nothing wrong with polybutylene pipe and that, in fact, polybutylene pipe is very reliable and better than many of the materials currently used for polybutylene water piping.
