Very Little Hot Water

[charliejamesuk]

I'm enquiring for one of my customers. They recently had a new cylinder installed (not by me) and since then they get very little hot water from any taps (just trickles out). All valves are correctly open. All I can assume is that the system was not correctly flushed when the cylinder was replaced. Could this be the cause?


Cheers

Hi. Check for air in the hot distribution pipe and cold feed.

Thanks for the reply. I'll check this when next over that way. Wont be easy as all pipework is burried in the walls/floors.

are you positive that the C/F valve hasnt snapped in the semi off position?

Prob airlocked, get a plumbers mate bung and cover the outlet of a mixer tap in the house. Open the hot water tap and then open the cold, let it back fill, close cold tap and remove bung. Repeat this until hot water comes thru

I just use my hand instead of a bung ....... and get soaked.

Hi Mbear - Do you mean to create a bung from the Plumbers Mate putty? Sorry if sounding dumb!

Hi Emerald - It was very stiff but did turn. I will check. Thanks

No, he means use a bung that comes as part of a radiator valve change kit. It is made of rubber and has a pointed male end and an open female end. Slip the female over the mixer tap and bingo. Try buying the Regin ones.

I know the ones you mean. I'll have to source a set. Hopefully from local merchant as don't want to wait for delivery from an online seller.

Thanks!

Try Parts/Plumb Centre, a little pricey though!
