boiler pressure keeps dropping

[aftermath]

Next time you bleed the rads, bleed from the highest radiator, down to the lowest

heres the latest update - since bleeding the radiators it lasted a month before i noticed on friday the pointer was out of the green section but not down to 0 but when i opened the taps to send the pointer back up in the green section it took longer for the pointer to move up,we still have the workmen fitting new water pipes in the streets and have been working directly to the side of our house and since friday our water hasn't been coming out with the same power/pressure so i dont know if this is something caused by them or the boiler/tank ? and the workmen have not shown up this morning to ask them. will hopefully get a plumber out this week but i need to find out if the water problem is caused inside or if by the workmen outside. is it worth bleeding the radiators again this time starting top to bottom?

You will get lower pressure while they are working on outside pipe work and this will cause filling through the loop to be slower. Its turned down for safety reasons.

i just caught a foreman as he was checking the works and he told me to try the stopcock with the water running i could hear a slight change in the water pressure but when i checked the taps in the bathroom and the shower they are still not working properly so he's going to get somebody to come and check,he said they have been changing the pressure in the area as they'd found a few leaks.

Hi quite an interesting thread all of the info should be useful but if you don't have leaks and water pessure still dropping more than likely you will be needing a pump soon. When you fill system it is sealed. Workmen outside has nothing to do with central heating losing pressure just coincidence. Best get your boiler checked winter can be cold.

we had our boiler serviced approx 1 week before all of the problems started, a workman was sent to sort out our low water pressure and he said that when they turn off/down the pressure to the property a pin has dropped out of the stopcock he fiddled with the stopcock for approx 1 minute and got the water pressure back up so we'll wait and see how the boiler peforms before getting a plumber out.

as i was going to bed noticed a noise from the toilet cistern and its filling with a steady trickle of water but it has what looks like an overflow pipe in it so its not looking like it will flood,when i lift the ball just out of the water it stops filling but i cannot rest the ball on anything and as soon as its in the water again it continues to trickle is this likely to be with having the stopcock adjusted today or is it yet another new fault? 2 a.m now so i'll check on it in the morning.

trickle stopped but now luke warm water

the water in the cistern was still a steady trickle but managed to catch one of the workmen who said maybe the pipe had sucked up some dirt with the change of pressure but he did manage to get it down to a drip,20 mins later i ran the bath and the water was only luke warm and the shower wasnt much hotter but the radiators are still nice and hot when they come on so its just one thing after another at the minute including a broken oven.

Hi Steve you are not having much luck are you. with water pressure going down because of outside work you will get dirt in your freshwater supply. If your toilet cistern does not shut off fully it's probably small rubber washer that's worn at join of pipe and ballcock arm 20p worth.The slow filling is purely down to water pressure or dirt at nozzle where washer goes. All of this is still unrelated to problem your having with heating. As for oven if it's electric and not heating up probably the element easily replaced. the element will have number or code use google or ebay. Always turn water off before attempting washer inspection same goes for electricity at oven. If your not good at diy please use professional. Better safe than sorry Good luck.

[footycard steve]

yes its an electric oven and did think it was likely to be the element but i dont have a clue what i'm looking at, had the heating on a bit and the hot water in the bath was definately warmer than earlier, have been in touch with council for list of approved tradesman, found out today our insurance company no longer in business and its due to be renewed this week so also have that to sort out now,

Check the thermostat in the cooker first.

Holy Thread revival. I have same problem butI've traiseld it to the pressure release valve as the pipe outside has watter dripping from it. Time to call the warrenty folks I think. As said its a sealed system so pressure outside dropping would not have had an effect on the pressure in your system.

[cablefreejunkie]

i just had the pressure relief valve changed at home,,the bath would take an hour to fill,now it fills in under 5 mins,,anyway my pressure in the system drops aswell,got no leaks as far as i know and ive bled the rads and pressured it up again etc,,not sure why it keeps dropping,,any ideas from any plumbers on here ?

[gizmo.1484]

Check the pressure relief pipe outside to make sure it is not dripping as the pressure relief valve might not have sealed properly when fitted.
If not dripping then there is defiantly a leak in the system. Check all joints around the rads.

the clown that plumbed this house before we moved in did not vent the pressure relief pipe outside,,he was a complete tosser with no skills whatsoever (dont start me off ive got a list as long as my arm) of total ~~~~ ups he has made in this house,,,anyway the vent pipe is in the cupboard with the immersion tank,,nothing is leaking well not above the floors that i can see although he has used easifix pipe to plumb the whole house and a coupleof the joints leaked at the kitchen taps
in all honesty it probably needs ripping out and replacing
