following on from earlier questions about Triton Showers ... our model
(X300si) has a 'low pressure' warning mode. In this mode, a light
flashes and the heating element is switched off. Ours has started
going into this mode regularly in the mornings. The pressure hasn't
changed and it seems to be fine a little later in the day. I've turned
the stopcock up a bit without effect; also I replaced the inline
filter not too long ago, so I don't think it can be that that is
blocked.

Any suggestions as to the cause?

Thanks

PS:

The Triton 'filter' is just a small thimble-shaped 'bundle' or
brass-coloured wire held within the 15mm shower inlet fitting. Rather
like a small version of those those stainless steel 'brillo pads' that
you put inside the kettle to attract scale.

Triton charge a fortune for these and I'd like to source an
alternative. However I've no idea what they might be called. Any
suggestions?

Thanks

Why not drop it in some descaler?

The water pressure may be low in the mornings for reasons beyond your
control. Is the show significantly above street level?
Are you at the top of a sloping street?

It does sound marginal maybe the sensor is down on the shower. Is it
possible to hold you thumb/finger over the end of a MAINS tap?

Hi Ed
Thanks for your comments:

I would have done this with the original ... except it fell to pieces
as I tried to prise it out of the pipe. They really are made to be
disposed of ... which is why I want to find an alternative supplier.
Can't remember what Triton charge, probably about eight quid each ;-(.

No, we're 2/3rds of the way down a hill and the water pressure is
strong ... with no discernable difference in the morning.

I will experiment a bit with trying the shower during the day. Any
ideas how the low pressure sensor might work, anyone?

Probably a bad sensor.

Generally they are a tough rubber diaphragm, a spring and a micro switch.

Hi all
update on this:

I did a bit more checking and it seems that on some of the Triton
models at least there is a design fault which causes the micro switch
to loosen from the PCB tracks. Armed with this knowledge I took a
closer look. This wasn't the case on my sample, but the way the
diaphragm and connected plunger contacts the switch (actually a
miniature 'pushbutton' switch rather than a proper microswitch) is a
bit vague. I fitted a new stabiliser valve assembly (which
incorporates the pressure diaphragm) a few months ago and there may
also have been variations between samples here. Anyway, I added a tiny
dab of hot melt glue to the 'spigot' of the switch, to make the
pressing more certain. Since then all seems well, hurrah.

Why it was consistently failing in the morning, and why turning on
other taps made a difference, I'm not sure. I wonder if too much
pressure was causing 'off-centre' pressure on the switch. Or the
cooler temperature in the morning was affecting the flexibility of
part of the mechanism. Or something...

Anyway, worth knowing that it seems a common failure point and easy to
address. Triton must know this is an issue but were suggesting a new
PCB at £100 etc. Not impressed.
