Water pressure drops when neighbour's use theirs... At my wit's end!

[sammathias]

Does it happen to your neighbours flat upstairs also??

Could be faulty stopcock as tge guys have suggested.

I have had blocked pipework but that tends to run full flow then die off just when you run a tap.

Sounds like probably a 3/4 or 1" iron main feeding the 4 properties that has become furred over the years . Good static pressure poor dynamic presssure. Has the plumbers checked the dynamic pressure?

Your main could run through dowstairs propertie, probably will. But it may also have a valve of sort partially shut down in your neighbours property.

Have you got your own outside stop tap in the road/on the path?

Sounds like poor mains pressure,does ewch property have its own mains?could be shared..
You could solve it by using a break tank and then feed into a pump to pressurise all your outlets.

I've had the water board out twice who have said the mains pressure is fine and when I run my taps the pressure is good. It's just this thing about it dropping off when the neighbour's use theirs.

Your main could run through downstairs properties, probably will. But it may also have a valve of sort partially shut down in your neighbours property.

I am the upstairs neighbour. Think of a rectangle split into 4. I would be top.

No idea if the dynamic pressure has been tested. I'll have to go Google that.

The whole street is the same style of houses, so from one mains point outside my gate, that supplies 2 blocks, mine and the one next door. They all say their water is totally fine.... It's just me!

No it's shared with my block and another as far as I know. It's been tested and has no problems though

Must all be fed off the one mains,And when someone else uses a mains fed outlet yours is last on the line.
You can avoid it by using a tank and then pumping into your combi

Might be a good idea to video the water flow from shower and a tap to show it going from good flow to poor flow to show to water authority, if no blockage or nearly closed valve is found.
You are paying for inadequate water supply

I don't understand why it just affects me though, surely it must be something to do with my plumbing or pipes within my house?

That's a very good idea and im going to do that so I have evidence.

We don't pay for the water up here so unfortunately I don't have that argument with them!

Try your stopcock.
