4/ 5

Pros: Does exactly what I wanted. Comes with flexihoses which connect to pipe with JG speedfit fittings

Cons: I'd expected an electrical cable to come with it.

Good quality pump, not quite up to my memory of Grundfos commercial pumps but still good for domestic shower

4/ 5

Pros: Good flow, easy to fit

Cons: Quite noisy,

The pump performs well it replaces a pump of the same type that started leakng through the shaft seal of the hot impellor after several years use. I believe this is due to air getting in the pump causing it to run dry. This is probably due to the fitting that takes water from the. Hot water cylinder rather than any problem with the pump

Pros: Good instructions,Simple to fit, Good build quality, good price.

Cons: No Electric cable.

This is the second time I have used plumb world in both cases next day delivery, Delivery driver very polite and helpful. Items well packaged, great value, web site very easy to use.
It took about three hours to fit including new pipework.
I had read reviews about the lack of cable so had this all ready.
Shower works great (no leaky joints)
