Pressure Fluctuations
Pressure Fluctuations
(OP)
Our water system is having major pressure fluctuations. They are ranging from 85 psi to 185 psi in a 15 second time period. We have a pressure gauge measuring the pressure every 15 seconds, 24 hours a day and have moved this meter to other locations. We are seeing this fluctuation throughout the system and know that our meter is reading correctly. Also, we are getting alot of complaints about people's PRVs going bad at their home and pop-offs failing on their hot water heaters. Any ideas?





RE: Pressure Fluctuations
The pressures youve quoted are extremely high. Is this pressure reaching the end user?
There are gadgets that can absorb minor shocks in water reticulation piping, and these have been fairly successful in preventing potable piping system failures.

Can you correlate the pressure spikes to pumps turning on or off? Valves opening or Closing and the like? If you can, this could be a classic example of water hammer.

Sorry, I didn't read all of the entries before my first entry.

a "bad" PRV wherein the sensor lines may be leaking, plugged, or otherwise deteriorated, a malfunctioning valve actuator, a damaged soft start on a pump, or a number of other scenarios.
A quick solution would be to install a surge anticipator valve in the line and route the outlet back to the reservoir/tank until the problem can be isolated.
