  • Mixer shower Vs power shower, talk to me.

    Our electric power shower recently shorted and no longer works, which was a (literal) shock. We're considering changing to a mixer style for safety and to hopefully avoid this happening again. Does anyone know of a way to test the water pressure before committing to the time and money involved in installing a mixer shower/decommissioning the electric jobbie?

  • If your boiler or hot water (pressurised by mains or by motor) is nearby then your pipe work shouldn't have too many restrictions, I favour aqua lisa for mixers that work well and flow a lot of water for years with no issues (new lower end Mira aren't as reliable as they used to be decades ago when they built their reputation).
    As above, do the cup or bucket flow test, the bigger the test sample the more accurate.
    Do the hot and the cold seperately, and then both together to see how the system performs under demand.
    Bear in mind most mixer on a combi boiler fall over when anyone turns on any tap anywhere else, so maybe see how that affects it too. Worth paying a plumber £50-80 call out fee for their advise though.
    Electric showers actually shocking people is a seriously rare occurrence*

    *Happened to me on our latest project, previous bathroom installer had pinned the 10.5kw shower cable (6mm2+ I think of copper) in various places through the tongue and grove ceiling so if you'd touched these whilst the isolater was in the 'on' position, many interesting things would have happened. When I fully removed the old installation (new shower fitted in 2019!!!) found that the insulation on all 3 wires was cut down to copper when they'd cut back the outer insulation, and was coiled up at base of inside of shower, where it gets wet. Fucking unbelievable.
