We have a "normal" shower - just recently we seem to be having an issue with water pressure.
What are the options?

The shower is plumbed in with electricity obviously - so how easy is it to install a power shower or pump under the bath?

we went with an electric shower in the end cos a power shower needs 2 water feeds, hot and cold. The plumbing would have been a nightmare, involving an additional bit of hardware screwed onto the top of the hot tank and a long pipe run from the airing cupboard, drilling through walls, boxing off pipes etc.. Electric showers just need one cold feed, much simpler job and as long as your water pressure is OK, it'll work a treat. Also if an electric shower packs up, they're much cheaper to replace.

easiest way is get water board to check pressure to the house, if its on there side they will repair it.

Think i've decided to change the 7kw for an 8.5kw or 9kw in the New Year. Got £10 from B&Q today so that'll come in handy.

no bigger than 8.5 or it will need a re wire to 10mm,
unless its a long length it may need 10 mm for the 8.5 but unlikely. let us know the actual length and we can advise.

also rcd req, depends on shower to the size of breaker req

It's got it's own power from the main fuse board - big thick wire(although it's been in for years). Probably will be 8.5kw actually 'cos they're on sale @ B&Q and the unit is large enough to cover the hole from the existing one.:hihi:

If its low pressure all though the house, see if your stoptap will open further.If the pressure to the cold taps is ok but not the shower,electric showers have a fine mesh filter to stop muck getting into the heating can. It will either be, just after the isolator or where the final connection is inside the shower itself.Worth looking at.Turn off the shower MCB in the fuseboard before removing cover
