“Working with subcontractors can be problematic, which is why we bring the Lunt-Marymor company onto our projects whenever we can. When they are doing the plumbing or hydronic heating, we can put our attentions elsewhere, because their professionalism makes that part worry-free for us.”

“Thank you so much for sending Michael! Not only did he fix the toilet, he noticed that the sink filter needed to be cleaned, and then took a look at the hot water handle in the shower which last time no one was able to fix w/ a minor repair. But Michael did with a simple washer, this handle had been leaking for well over a year because I thought it was going to be too expensive at the time. So keep him, give him a raise. Thanks!”

Pressure Regulating Systems

What is Water Pressure?

The downward force of water upon itself and other materials, caused by the pull of gravity. In other words: the energy that drives the water through the pipes. This energy is expressed in terms of pressure, and measured in “psi” (pounds per square inch). 55psi is considered in the mid-range of normal water pressure. The normal pressure for your property will depend on its physical relation to the water source supply (tanks and reservoirs). If your home is at a higher elevation relative to a tank’s location, you will have lower pressure. Conversely, the lower your home is located downhill from the tank, the higher the pressure. Water pressures in flatland areas are based on reservoir water levels, assisted by the use of booster pumps.  

High water Pressure:

Excessive water pressure (above 80psi) puts unnecessary strain on the water heater, water lines and fixtures, which can result in leaks. Higher pressures could rupture pipes, damage fixtures, and injure the people using them.

You may notice symptoms of high pressure:
