Stuart Turner Monsoon S Positive Head Twin Shower Pump 3.0bar is rated 4.4 out of 5 by 27.
Rated 4 out of 5 by from Quiet Had to replace a ten year old Grundfoss shower pump. Installation was straightforward - a bit of plumbing needed changing but once done the pump was plumbed, wired and commissioned in about 45 minutes. Much quieter than the Grundfoss. Very pleased.

Rated 5 out of 5 by from Early days but....... Only installed yesterday but easy to do and is noticeably quieter than its predecessor. The pump appears very sturdy and having a 5 year guarantee gives confidence. Only time will tell but an auspicious start

Rated 5 out of 5 by from Great shower pump I purchased this as I direct replacement for a previous version that had seized up (no idea how old it was). Once the old one was fought away from the seized up push fit connectors and the existing pipes were cleaned up the new one was simple to install and worked perfectly.

Rated 5 out of 5 by from Excellent Quality I bought this pump to replace a Stuart Turner Trevi 45 model, which had lasted for probably 19 years. I chose this model because of the increase to 3 bar pressure, the fact that the pump assembly was made of brass and that the inlets and outlets were both 22mm. My shower is 8 metres away so I needed a pump that had the capability of getting the hot water to the shower head quickly. I was not disappointed! It was easy to install as I already had isolating ball valves in place. The flexi connections similar to tap connectors are easy to fit to the pump. The other ends are push fit so you need to make sure the pipe is not damaged. The pump has built-in strainers for the hot and cold water inlets, which is a great feature.. The pump is slightly quieter than the one it replaced and provides excellent pressure. I am really pleased with my investment.

Rated 5 out of 5 by from Great shower pump I purchased this as a like for like swap as the last monsoon pump gave up the ghost after a good 10 years. Feels a quality model and with a 5 year warranty hoping it stands the test of time. All fittings good quality and easy to fit as a replacement diy job. One small tip would be to simply cut off the old push fit valves as after a good 10 years without moving they were not going anywhere :). New ones simply slide on. Easy click and collect ad always from Screwfix and great pricing.
