Fault finding

When i turn my Triton Rapide 3 on it starts fine but after 30 seconds the water starts to come out in splurts like a pulse and the low pressure light is flashing. Sometimes its fine sometimes its not and normally works ok again after a few days but then the problem comes back. Any ideas on whats causing the problem?

The things to check firstare:

1 That the main valve cominginto your house is fully open.

2 Then check that the valve on the line to the shower isfully open.

If these valvesare not fully open then there may not be enough water getting to your shower.

Make sure that the shower head isclean and clear, that the hose isn’t kinked (this can happen just behind thehand set where it is difficult to see) also check the inside of the hosealthough it can look OK on the outside it could have collapsed internally

The other possibility is a faultyflow/stabilizer valve not allowing the correct amount of water into the shower.

A rough check is to remove theshower head turn temperature control to fully hot the water coming out of thehose should be a bit more than a dribble then turn to fully cold and it shouldbe coming out at full flow.

Ifthere is not much difference between the two then you could have a faulty flowvalve.

Carry out this checkafter you check the inlet valves.

Also as it is a Triton have a look at the outlet TCO

The outlet Thermal Cut Outthis is a black disk with two wires going to it and it is mounted on the out letpipe (The bit between the heating tank and thehose)


Examine theconnections closely if you see any discoloration / signs of overheating then theTCO needs replaced.

Open / close the safety device that allows power throughto the elements.

The low pressure light coming on usually indicates the solenoid, you can check it if you have a multi meter, you shouldhave a reading of at least k3.5 ohms, across the two terminals any less and youneed a new valve. (Check the valve in the failed state.) (When it has stoppedworking!)

If thereis power getting to the solenoid and it is not operating then there is a goodchance that you have a faulty solenoid.
