is it possible to replace a noisy Mira Power shower with a new one myself without the need for a professional plumber?

If the shower and pump are seperate and you can safely turn off the water and electric . then go for it.. please put your safety first at all times.

yes its very simple isolate water and electrics if needed then change over very easy make sure water is on and unit perged before electric on

All things are possible!! most items come with a set of instructions, check the pipe location and spacings against the new unit first as some adjustment may be requiered. If in doubt call me!! regards Ashley

yes you can !!!!!!! just make sure water and electric are isolated before removing anything also and i repeat also some mira and aqualisa cartridges are around £120 to replace so it is very important to flush any debris through after fitting and before use otherwise loose particles and even metal shavings inside when unit is made can clog and break the vital parts which are costly
