Shower Mixer Doesn't Cut Off Hot Water When Turned Off

[DavePrior]

Need your help please guys.
Friend of mine has a mixer shower that he bought 2-3 years ago, make unknown. About 12 months ago it stopped cutting off the hot water when he turned off the shower. I've popped round to check it out, and I suspect it can be fixed, hence my plea to you guys !
I have a picture of the innards, which I am attempting to load.
Many thanks in advance.

Sorry, not a very good description ! The right hand-side as you look at it has what looks to be a shut-off valve. The plastic internals seem to have some form of pressure shut-off (?), and my guess is that there are some rubber seals or similar in thre that I can replace, but obviously with my utter lack of knowledge on what's going on I'm loath to dive right in.

Any ideas at all guys?

Email showerdoc.com. They'll probably
a)recognise it and
B) sell you a reurb kit

It's a venturi shower, the old Croydex one. I don't think you can get it, or parts, anymore. You might want to look at replacement venturi showers - only two on the market, the Treviboost and the New team Jetstream.

Thanks Chris - that may also explain why they are having trouble with the temperature, since they have a combi. Mystery solved - nice one!

Many thanks....
