Bought this pump to replace a 5 year old Grundfos 2.0 bar. Plumbers I used replaced it quite easily.

The pump is very strongly built and should last for years. It is very quiet in operation unlike the pump it replaced and provides a good pressure for a shower. An excellent product

Delivery was very timely and within days of ordering.
I picked this pump as I wanted to provide additional water supplies to 2 showers. One in the main bathroom and the other in the ensuite bathroom.

Installation instructions very clear.

I installed the pump in the airing cupboard next to the hot water cylinder, so the hot water inlet supply from the cylinder was easy to rig in 22mm copper pipe.
The cold supply came from the header tank above, via a straight run down the wall. The discharge pipes from the pump were vertically up to the loft space and over to the bathroom shower. I installed 2 off 22mm "tees" to branch off to the ensuite shower.

Cold to pump and hot and cold from pump all in 22mm speedfit piping.

This pump certainly makes a great difference to the showers as we now have "power showers" in both bathrooms.
I can most definitely recommend this to anyone seeking a similar solution to poor water flows/pressures.

Really fast service from the web purchase. Well packaged delivery. Pump is so quiet! Bigger than our old cheap pump so needed to replumb the install to fit the old pipe configuration but no doubts we made the right choice!

At first glance one can see that this pump is beautifully made, with the purposeful design of the motor being augmented by beautiful brass water housing and connectors. It definitely looked a quality piece of kit - and performs as well as it looks, supporting the old engineer adage " if it looks right, it performs right" !
Pump is easy to fit and performs well - definitely the strong but silent type. The quality of construction promises many years of trouble-free service.

This pump was purchased to replace a Bristan HYPUMP100 which is no longer available, it is the same size and and was fitted without having to alter the pipework.

5/ 5

This pump was straightforward to install, it looks good, and functions very effectively.

Even the Grundfos packaging is well designed!

It comes with 4 push-fit 22mm flexible adapters. These don't have integral isolation valves, but this wasn't an issue for me because my installation already had adequate means of isolation and drainage.

The brass construction and continuous rating make this unit more expensive than plastic alternatives, but hopefully this will pay off in the long term.
