Reliable pump but noisy
The pump was so easy to install and is working well, the grundfos name should mean it will be reliable for years.BUT my only problem is that the pump, like most if not all shower pumps, is so noisy which is a big disappointment as when I shower at 5:30 AM it wakes the household up.Surely in the era we live in pumps should be very quiet for example central heating pumps, they don't wake people up in the morning.

Works well and pretty easy to install
Ok so it's early days as it's only been in service for a month (Oct 07 2020) but so far so good. This pump is what I'd describe as average as far as noise is concerned (I've installed a few over the years). I've mounted it with its feet on tiles on a thick rubber matt under the bath. The noise level is fine. Flow rate is good for a single shower (all 22mm copper with 1.5 m head) and OK with a typical thermostatic mixer - wouldn't want to run more than that off it. I found the right angle bends in two of the push fit flexible couplings were no use for my installation 4 straight connectors would have been perfect. So I had to buy two extra which I included the cut off valves needed to do the job properly. These replacement flexi's had 3/4" brass nuts. Was a bit worried they'd chew up the threads on the pump and fail to seal. But all is fine. Also the supplied cable is too short to make it out of the under bath area. So I had to replace the cable, which meant opening the box on the pump. Live and Neutral are simply connector strip screw downs but the earth is a crimp!! I guess Grundfos never throught you need to replace the cable..... lol

Great shower pump from the build quality and design point ...
Great shower pump from the build quality and design point of view, and it provides plenty of shower pressure, but its like being in a bathroom with a jet engine running, not acceptable noise levels as far as i'm concerned, will being waking the neighbours up with this beast at 5 in the morning. Have used 3 different pumps over the last few years, and all don't seem to last very long these days, this is far and away the noisiest. Update.....well it is still going strong 4 years later so despite the noise and now not having to use early in the morning, very reliable and still delivering good pressure.

1 Star as it stopped working after a month.
Motor burnt/stopped working after 1 month of use. It was professionally installed but still looked relatively easy to install. Its a little loud when running but thats expected.

But with sound and vibration base.
Very good value from Amazon. Had a professional fit it. All good and a quiet pump. I recommend you buy the sound and vibration mat to install it on. Really makes it quiet.

Good value for money
Good pump, not so noisy as my previous grundfos stc-2.0. Only rate it 4 stars because it seems the pressure is a bit lower when compared with my old grundfos stc-2.0 although this pump is rated 2.0 bar it feels like 1.5 or 1.8 bar.
