Good spare for leaking shower
Reviewed 12 years ago

We have two 10kW Triton showers, both of which developed the same fault after about four years' use - cold water started dripping out of the base of the shower control and over a period of a few days the heat control had to be turned progressively hotter to maintain temperature. In both cases it turned out that the stabiliser valve assembly had developed a leak. Once the replacement valve assy was received (roughly four days from ordering), replacement was relatively simple (ie) electrical isolation of the shower, releasing the heater element to pull it away from the case sufficiently to take the stabiliser valve out (from memory, a matter of undoing six cross head screws). No o-rings are supplied with the replacement so I just smeared the existing o-rings with a touch of silicone grease and re-seated them. There is also a white plastic piece that you need to take off the top of the old valve assembly and put on the new one (this activates an under-pressure shut-off microswitch). Other than that, re-assembly was just a matter of doing things in reverse order. The only pratfall I spotted was to ensure that the outflow to the heater assembly is reassembled tightly against the heater or it will leak. In both cases the replacement valve assemblies did the trick and the showers are working well.
