The mains water pressure in my 1930s house is shit, to the point where the toilet won't fill if the tap downstairs is on.

The water company have been round and confirmed the pressure to my house is fine.

My theory is that my stopcock is fucked, what do you guys recon? It's quite rough to turn and even when fully off a small trickle of water will come out the tap when on.

Is there anything else it could be?

Cheers

Yea all the cold taps in the house have the same poor pressure. The hot water runs off a tank and is fine, however the tank can be slow to fill if say the washing machine is on.

How you planning on changing your stopcock?

Would need to be turned off outside the building.

Yea it does. There's a shut of valve under a hatch in the front garden. Once turned off it looks fairly simple to change the stopcock.

The same as you would usually change one, by shutting the water off outside

Before you connect it to the rest of the house connect the mains end up and blow it threw for a while into a bucket

Well after ripping all the wood off arround it to get a good look I can see my house has the old school lead piping running into the house.

I asked a mate about it and although it should be ok to change, he said the old lead pipping may be abit if a pain to connect a new stopcock to so he is popping round at the weekend and giving me a kit to repair the stopcock whilst leaving the body in place.

Hope it is the stopcock as iv heard that lead piping can get blocked and I don't fancy spending a day or two digging up the front garden to instal a new water pipe!

Surely with the high pressure from the mains water, the bucket would be filled up in like 5 seconds?

Mains pressure is just what comes out of your kitchen tap.

When I was replacing a faulty valve and fitting a new one elsewhere recently, during my valve operation tests I'm pretty sure the pressure was much stronger at that point than from the kitchen tap.

the pressure is the same at all the outlets, you will loose a bit of flow rate through the pipes though so you will fill the bucket a tiny tiny bit quicker at the stop tap than you would at the kitchen

We must have a shit tap TBH (it's a bit fucked anyway) as when you open the cold tap completely you don't get gushing water coming out of it whereas you do from say the garden tap for example.

New stopcock fitted but it hasn't solved the problem.

Looks like I'm going to be fitting a new waterpipe through my front garden into the house.

On a brighter note another mate (sparky) popped round and confirmed my plan for wiring in an electric shower is sound. He's also offered to give me a hand doing it and said he will re-wire and install a new fuse box for the house whilst he is at it (it's only arround £100 for a new one)

Iv noticed a couple of threads in here about installing electric showers so if anyones interested I will take a few photos of how's it wired in to the fuse box and how the cable is routed to the shower
