Shower safety valve?

Also, It does it when the heater is on and when it is off.

When we had a similar thing (with a Triton shower) it was a safety overpressure cutout that had gone (just a diaphragm that ruptures). Had to get a replacement from their spares dept for the whole main heating unit and practically dismantle the whole thing to fit it. Luckily it was only a month old so they sent us it for free..

it's the safety pressure switch thingy i.e a piece of poly thet breaks down. can replaced easily

If they still stock them for my shower. It's a Triton T70i.

(Thanks to TLC for having the info easily to hand)

I had the same problem with a Triton shower from Wickes. I went to our local store, Wickes of Broadstairs, and asked they had a spare anti-scald device. I was told that they don't stock spares, but that I could use their 'phone to call Triton's spares service, which I did at about 3:30 PM on a Friday, and ordered the part, thinking it would probably be a week or more before it arrived. Imagine my surprise and delight when it arrived at about 10AM on the following day!

I have felt guilty ever since that I didn't publish my admiration of Messrs Wickes's, and the Royal Mail's, efficiency. Please accept a big THANK YOU BOTH!

Surely, more praise due to Tritons spares dept, who I have always found to be very, very good.

So too is Mira's.

Thanks for that. I have just ordered one.

Any tips on fitting one? Looking at the diagrams, it seems to be hidden in the can assembly somewhere...

It's about 15 years ago I did it... I recall taking the thing apart and reassembling it without anything more complicated than a Phillips screwdriver and a pair of pliers... no soldering, sealants or that sort of thing involved.

Remember to turn the power and water off to it first ;-)

Is just switching the red switch outside the bathroom safe?

Bob

Sounds like a double-pole isolator, in which case yes. As long as nobody else is likely to switch it back on! (It *should* be an isolator to meet the regs).

If you aren't sure, then in all likelihood there is a dedicated MCB (switch) in the main fusebox for the shower as well. It'll be a big one - 30A or 45A.

It arrived today (ordered yesterday) - I say "it", but they sent a pack of 2 with an instruction sheet. Basically a 10 minute job - Take the front off, undo 2 screws, pull the pipe assembly out, and swap the thing at the top of the clear pipe.

The valve is a small rubber coated plastic ball inside a plastic tube. I did find a small plastic ball floating around, so I put the old one in first just for laughs. It was OK, until I turned the pressure up, when it popped again. Must be a combination of the new shower head / riser (less/smaller holes = more pressure) and old PRD (softened rubber on the ball?) because the new one worked fine at full blast with the new shower head..

I also took the opportunity to put the power neon back on the front casing where it belongs. I wondered why there was an orange glow near the outlet when it was on. Didn't think the can got that hot...
