Hi.
Before I start taking things to pieces I thought I would check with the experts.
I have a renovated cottage with all new plumbing from the cold water mains. The system is mains pressure. There is a stopcock, filter, check valve and pressure reducing valve with a gauge. The mains pressure into the property is around 5 bar. The PRV is set to 3.5 bar with no taps on.
When a hot or cold tap is turned on the pressure is good at the tap then reduces after a short time (about 5 seconds). The gauge on the PRV reduces to around 1 bar when a tap is on. On turning the tap off I can hear what sounds like the pipes repressurising for a few seconds.
2 questions...
Could this be the filter partially blocked or a PRV problem?
Normally, would the gauge on the PRV show set pressure of 3.5 bar when a tap is on or would it normally show less than the set pressure?
Thanks
