[Closed] Any plumbers in? Water pressure content.

mains tap or tank fed? (assuming cold?)

which taps have low pressure (cold? hot? kitchen? upstairs bathroom? downstairs bog?)

Do you have a cold water header tank?

Yes cold and main tap at the kitchen sink. We had the tank in the loft removed about 5 years ago.

We've not had any work done so this is just out of the blue.

toilet still filling quickly?

hot water ok (assume it's a combi boiler)?

Oh, and all the other taps in the house too. The pressure in the hot tap seems to drop very quickly. The cold one take maybe 20 seconds if it's been off for a bit.

Yes, combi boiler. We still get hot water but it's a trickle by the time the heat has come through. Toilets filling slowly.

It's like when all the taps are off the house pipes "pressurise" then when we run the taps it drops.

have you asked neighbours if they are suffering similar symptoms?

Do you have an inline filter after the main stop tap?

[s]Will need to shut off main stop tap, drain your cold water supply (should be a drain valve near the filter if you have one) then inspect the filter[/s]

Unlikley to be that if you get pressure for 20s. 1s maybe, but not 20s

Sounds as though the mains pressure has dropped for some reason in to your house. Neighbours having the same issue?

Sounds more like a blockage somewhere - the pressure rises to normal over time (which suggests that the mains pressure somewhere is ok) when everything is turned off but if you turn a tap on, the mains water can't feed to your house fast enough to maintain the pressure.

I've not asked the next door neighbours (at work) but my mate lives two doors up and said they're not having problems. No inline filter as far as I know (think it's unlikely as the house was built in the 50s and had the original oil fired central heating when we moved in). We're in Glasgow so no issues with hard water/limescale.

Been an issue since Sunday but we had a mains leak locally during the summer and I assumed they were just doing work.

has there been any digging up by any utilities going on in the road near you?

As above, check the neighbours first.

No digging that I've noticed. I'll drop round the neighbours tonight. The suggestions that there's maybe a blockage somewhere was kind of what I was thinking too. I find it odd that Scottish Water are saying "not our problem" as it sounds to me like something's maybe come in off the main and got blocked.

I'll maybe give them a ring back tonight too.

Turn off the water at stop tap, run all cold taps, and flush toilet, leave until all water stops running.

Then slowly turn on stoptap again and see if that clears the problem.

Also look for any unexplained leaks or puddle in the house or in the garden.

Place large screwdiver on stoptap and ear to handle of screwdiver listen for whoshing noise, it will indicate a leak if no taps running.

My in-laws had persistent low pressure. Water board swore blind it was nothing to do with them. In the end they paid £2000 to have the pipe from the main replaced which sorted it. Rusty iron pipe...

Thanks project, will try those suggestions tonight.

Anyone any idea where the water company's responsibility is to? I know telephone is anything before the master socket. Is the water boards before my main off? Or is it the T-handle one in the street?

[i]where the water company's responsibility is to?[/i]

the t handle/meter bit in the street. Normally anything under your property is your responsibility plus a spur to the main/on street stop.

+1 clubber - not pressure but a blockage/faulty valve.

@Murray thanks for that diagram, will be very useful. I've phoned Scottish Water again and they're sending someone out to take a look. Spoke to a nice girl in the call centre who was very helpful. I think if they've not got work in the area they just initially tell you to call a plumber.
