Water is one of the most basic necessities for life. It can also be one of the most destructive forces in nature. That is why it is so important to make sure that the water piping and fixtures are protected.

Potable Water

The “drinking water” that is delivered to your home, either from the city or a private well, is known in the industry as “Potable” water. This term implies that the water is safe for drinking. Many of our customers benefit from Anti-scale devices and water filtration systems to improve their water quality. Clean water does not only benefit your health. It can also prolong the life of plumbing fixtures such as your water heater, toilets and faucets. Call Cathedral Plumbing for a complimentary water quality test to ensure that your family is safe.

The pressure that the potable water is delivered to your home varies depending on the municipality that you live in and can also be affected based on the time of year. The municipality in which you live has to adjust the pressures based on the expected demand of the community. For example, during the summer, most municipal water departments will increase the pressures to accommodate higher usage during the day. This can play havoc on your piping connections as well as your fixtures. Pressure that is too high can cause problems such as rattling pipes, dripping faucets, running toilets or even premature rupture of your water heater tank.  

Most fixtures are designed and rated for pressures ranging from 40psi to 60psi. Any pressure above 60psi is considered Excessive. Pressure above 70psi is considered High. Pressure above 80psi is considered Extreme.  There are some areas around the Dallas/Fort Worth Metroplex where the water pressure is as high as 110psi – 120psi. 

Install A PRV

One solution to control these pressure spikes is to install a Pressure Reducing Valve (PRV) on the water service line. This is an adjustable valve that lets you regulate the water to the desired pressure. As with most repairs to the potable water system, if not performed properly by a licensed and insured Plumber, your property or even health can be at risk.

There are several types of material that are used to make up your potable water distribution system. Some examples are galvanized pipe, copper, PEX, PVC, CPVC, and Quest. Each of these piping types has specific methods that must be performed in order to maintain the integrity of the entire system. From Brazing to soldering to solvent welding, rest assured that your Cathedral Plumbing of Texas licensed service technician is a trained and certified expert.

How To Check for Leaks
