Too much mains pressure...

[Bossfan01]

Hi
We had a combi boiler fitted a while back so the house is now all at mains pressure. Although this is great for watering the garden, all joints and taps are under a tremendous amount of strain I'm guessing.
It's a shared main which T's off from main and then T's off to mine and my neighbours house.
The bath tap started leaking recently and I'm wondering if it is becasue of the pressure. The tap is a bath mixer filler that takes a cartridge, but is hardly ever used as the seperate shower is used on a daily basis. With such seldom use this leads me to believe that it has been caused solely by the pressure on the tap. Is this possible?
Is it possible to somehow turn down the mains pressure by fitting something ?
Someone advised me to turn the main stop cock ''down a bit'' but I can't see how this would help as the pressure would still back up on all joints.
If a pipe or joint was to pop we'd be under several feet of water in no time at all. Any ideas or thought anyone ? Thanks

Most mains pressures are between 1-3 Bar.

A very few can go up to 10 Bar but thats unusual.

Most pipework, taps and boilers will stand 6 Bar. Particularly soldered copper. I always wonder about plastic push fit joints as they can come apart if not correctly installed. Washing machine hoses do sometimes split but should be able to stand that pressure.

If your pressure really was over 3 Bar then you can have a pressure reducing valve fitted.

Its not always done but I would couple that with an over pressure release valve.
