Reducing water pressure (domestic)

[Cos-enfrance]

Hello,

I am an individual and want to put a question concerning the water system in my own house (in France).

I had an Actaris Isobar pressure reducer installed at the head of the water system by a professional plumber about 4 years ago. The pressure gauge on it reads 2.4 bars and I want to bring it up to 3 bars. For the operation, all taps are closed. I find that 3 complete turns of the adjuster screw (3 x 360°) has no effect on the gauge reading. That surprises me.

What I now wonder is whether 3 turns on such a device is very little or whether I can already deduce that something is not working properly?

If anyone here can give me a steer I would be very grateful.

Thanks in advance

It's an old valve and gauge and either could be faulty, or maybe your incoming water pressure is only 2.4 bar.

Thanks, Mountainman for your quick reply. The pressure reading has always been at 2.4 and I know that the incoming water pressure is not always at that level (if it ever is).

I understand you to mean that 4 years is "old" for a valve or a gauge. Is that right? How often should they be changed, in your opinion?

Kind regards,

Pressure reducing valves generally need to be installed with the head NOT downwards cause
crap from the main can jam them up. Even so they actually a device that requires servicing
from time to time. You can generally open them up and clean them out or just go and get
another. Honeywell do4 is the best we have used - very smooth adjuster and not too
pricy compared to far eastern copies which are only £5 less.

The useful life of a PRV or gauge depend on several factors.

Quality of gauge/PRV.
Hardness of water supply
Quality of water supply (silt etc)
High usage of water (wears out)
Very low usage of water (seizes up)
Extreme variations in incoming pressure.

And probably many other factors I haven't thought of.

It might be worth disconnecting it and seeing if the filter (if any) is partially
blocked.
