Water pressure issue

[Emma Hegarty]

I replaced my immersion heating element yesterday and when I reconnected everything and turned on all the stop cocks, the water pressure is exceptionally low when it used to be very good and there is no water coming from the hot water tap in the kitchen. I wondered if anyone knew why and how I fix the pressure? Thanks in advance

Check all stop cocks are fully open.

might be airlocked - when you opened stop taps did you leave the taps open at the same time ?. if you have a mixer tap in kitchen block up the common spout and open the hot tap 1st and then the cold mains side and wait for it to rumble and it will eventually be ok. You will get wet I always do - let us know how you get on good luck

Chances are the gate valve that is connected to the bottom of the cylinder is not opening properly.

Ok ... how do i open it ?

Yes they are

 

[Harvest Fields]

Ok . how do i open it ?

If it has partially seized I would drain it all down and replace it.

I have two separate taps in the kitchen and the bathrooms... there is a trickle of hot water in the bathroom but nothing at all coming out of the hit water tap in the kitchen . The bathroom is downstairs btw . Not sure if you need to know this

Replace what sorry? The whole tank?

 

[Scott_D]

Is the loft tank full?

 

[Emma Hegarty]

Is the loft tank full?

Yes

 

[Harvest Fields]

Replace the gate valve in between the tank in the loft and the cylinder in the airing cupboard

Ok thank you! Will that sort out the problem with the pressure for the cold water as well or is that a separate issue ?

Probably just an airlock like rob said to be honest. You would know if the gate valve has snapped partially closed as the head will just keep spinning.

Ok sorry to be a dufus but is the gate valve at the bottom of the water tank in the kitchen or the loft tank? There's a thing on the loft tank that I think is meant to kind of Bob up and down but it's just spinning. .. is that it?

I'm heading out here .. Will check my messages in a couple of hours. Thanks!

Or be very stiff and not move much at all

Ok so I have turned off all of the stop cocks again and all on again and bled everything i can and I still have no water coming out of the hot water tap in the kitchen. I think I'll have to call someone out

did you do as I explained its dead easy and works

I stand by this statement

 

[Emma Hegarty]

Ok thank you. The water isn't going out of the cylinder tank to the kitchen sink ... and the bathroom water that comes from the loft tank is coming through but very softly and if I turn all the taps on then no water comes out of any of them.

I did that but the tap is making no noise whatsoever

 

[Emma Hegarty]

I blocked off the taps and turned them on but the hot water tap is dead as a doornail. It's making no noise at all

Yes you're probably right as I have used wd40 on the valve in the attic and it did screw down but then it hasn't really caught the thread and just spins so I think it hasn't opened. Do you know if it's an expensive job to get a plumber to replace this part?

 

[Harvest Fields]

That depends on the engineers hourly rate if I am honest. Sorry to give such a vague answer.
