Plumbing Question

Waterfall bath tap/sink tap - what pump?

I use 22mm pipe throughout my property, tee-ing off to 15mm for each applicance unless it uses 22mm like my bath taps.

Having recently installed my cascade waterfall taps, as much as the cold flows lovely through them, the hot from a gravity fed cylinder on the same floor is a dribble.

What pump/bar would anyone recommend to provide a nice bath quick fill and enough water to flow correctly over my hands to wash them.

A future ensuite shower will also use a rain head shower ceiling mounted, so must be able to provide a powerful shower experience.

I also understand i need to fit a surrey flange to prevent bubbles/air getting into the pump ontop of the cylinder.

you would need to check your flow rate from the cold tap (is this direct from the mains) if so once you know the flow rate then you can buy a single impeller pump to attach to the hot feed under the bath, if you put it in the airing cupboard the all the hot water taps in the house will be pumped. Your shower if pumped will need a direct feed from the cold tank and be the first T off the hot water supply or surrey flange. Remember you need to check the size of your header cistern in the loft to make sure it holds enough water for the pump not to run the tank empty.(you can find how to work this out on the internet). Hope this helps

On selecting the correct type of pump to suit your system and needs, go to: these are very good residental pumps, a little pricey but well built and reliable, they also have a shower/hot water circulation pump guide if you need help.
