It is just a standard shower over bath, not electrical. Distance - I reckon about 5 - 6 feet If I take the shower head off the holder and hold it lower, it makes a marginal difference to pressure, very marginal or may be none. Tank in loft is a small one. However in the airing...

Hi Guys, I moved in to this house an year ago and have been dealing with extremely low pressure in shower. It is a Y plan system with condensing boiler on ground floor. Hot water tank on 1st floor bathroom on 1st floor some other tank in loft Pressure in taps is fine just the...

Hi Guys, I have managed to fix a couple of issues myself with help from this forum and I would really appreciate some more help. My shower pressure is too low, I have tried changing the head but it made no difference. Is there anything else I can do, I am willing to call a professional on...

either. as soon as HW is off either through program or manual it will knock CH off as well

Is it worth replacing the valve itself or do you think taking the motor head out and putting it back again might resolve the issue.

It will be in the airing cupboard [assuming you have the same system as mine]. Mine has three pipes going in/out from it. Have a look and may take a picture and people can point it out. Note any numbers or model etc. it will help identify what is what.

Sounds similar to the issue I had recently. If you have the same Y plan system you might find this useful http://www.diynot.com/forums/plumbing/boiler-only-turns-on-with-hot-water-not-with-ch.299877/#2188650

Hi Guys, I had the classic case of hot water and CH but no CH on its own. After much research and useful helpful on the forum, I ended up replacing the motor Head. Now CH comes on its own :-) and stays on for as long as I want. However if turn HW on with the CH it goes off when HW goes off. I...

life saver mate, thanks. I do have a thermostat thing in the hallway. All radiators just look bog standard.

oohh dear, what would have happened had I left the valve closed for long. Could this be the reason that Grundfos pump is making a loud noise.

That attempt using the tape was an absolute waste of tape. It stopped the leak for may be 2 minutes.

Tom, much thanks, I have just figured out what you meant by gland nut and I have tightened it a bit, it did seem a bit on the loose side and turned easily for about 3/4 of the way. Feels all tight now. The valve is set full clock wise, shall I leave it like that ?

Thanks, what does it do and which way should it be normally ?

See the valve circled in blue. I am not sure what this valve is and which way it should be. This is the one which is going in to hot water tank and the other end is joining the pipe between pump and divertor valve. Its leaking since I turned it in an attempt to fix my other CH issue. Now...

Guys, thanks ever so much for all the suggestions. I received the valve today and I have just finished replacing the Motor Head Only. Turned CH on and boiler came on straight away, on and off a few times and it seemed fine working on its own. Then I turned the HW on along with the CH, now...

Hi, I am about to order a replacement for my divertor valve which says 4037A1039 at the back. Has it got to be 1039 or 1088 will fit as well ? Which one would be better ? any help, much appreciated.

thanks, I will have a go at changing it myself. I am hoping wiring will be straight swap, if not I am in trouble.

After following guidelines by Hailsham, I can separate Valve and Head, not sure if I can separate the motor part inside the actuator though. It is V4073A 1039, any ideas where I can source just the head from. I have checked screwfix and they seem to do the full thing. Also in a situation...

valve or just the actuator ? is it worth having a go at replacing the motor head ? When I remove the head, valve seems to be moving fine.
