The PRD 'popped' in our Triton T50i today. Seems that I'd neglected to
descale the shower head for a while. Oops.

Is this a straightforward DIY job? It's the type that fits the bottom of
the 'can' (pn 83301330). I had a very quick look, and I can't see an
obvious way of doing the job without removing the can. Also can't seem to
find a download of service bulletin No.54 that would help me decide if this
was DIY or call in the tame plumber.

Thoughts?

IME you may find you need a new boiler as well (the electric heater
can assembly for the shower).

I used to think the brain was the most interesting part of the body
- until I realised what was telling me that

The can seems OK. Put a closed-off tube on the output from the PRD (there's
no real pressure there), did the installation procedure (not really
necessary) and the shower works fine. Apparently working much better than
it did before, but that's because the shower head was so badly scaled.

PRD ordered should be with me tomorrow AM. Can't see how much I need to
take off to fit it though. Hopefully the service bulletin will be
enlightening

If it's anything like my Triton (x300si IIRC) then it's pretty easy.
My surprise was that it was such a crude arrangement in the first
place ;-/.

You unscrew the cover screws, and then undo the nut holding the exit
pipe arrangement onto the boiler output. There are a couple more
screws to undo to get a fitting out of the way, and then the PRD can
be pulled out. Refit is the reverse. You need to be careful to ensure
that the o-ring fits properly, and that everything is snug so that
tightening up the screws causes it all to lock in neatly. Given the
design I was amazed it didn't leak in the first place.

I have also considered fastening the overflow pipe onto the PRD in
some way - it's a pretty loose fit and I have have water coming
through the ceiling below when it came off and the PRD ruptured.

Nowadays I keep a spare PRD handy as I've had them go a few times.
Teenagers having too many showers, shower head not being cleaned, that
kind of thing...
