Rated 5 out of 5 by from Seems to be a great choice I brought this as a replacement for my old leaking TREVI 45 TWIN and other than having to change the local pipework (location of outlets and change from 15 to 22mm pipe) it was easy to install. It works like a dream, quieter than my old one and even though it is supposedly 0.5 bar less powerful it seems much more efficient - perhaps that is to do with the age of the old one and the change in local pipe size - whichever, the whole family is really pleased with the result.

Rated 5 out of 5 by from YOU GET WHAT YOU PAY FOR This is the best pump by miles, my old cheap pump died, and I tried to repair it many times over a year until it finally gave up! I was recommended this pump and was a little put off but with the price, but wow I'm so glad a spent the money! I should of purchased this pump years ago! Very reliable, easy install and a 5 year warranty #jackpot

Rated 4 out of 5 by from Good pump Bought as a replacement for 20 year old Monsoon that had died due to rust. Very good pump as was the last one, only let down by the flexible hoses that collapse if not kept straight. The old pump had wire springs around the hoses that kept them firm.

Trevi 45 Replacement

The existing pipework to my failed Trevi 45 is 15mm. To change to 22mm would require major changes, Is it possible to simply use reducing couplings? I have approx 3 metre head.
Asked by: startingtopuff47
Hello Trevi, We specify 22mm pipework with the Monsoon pump to get the maximum flow rate performance possible. That said, using reducers to 15mm pipework should not present a problem, as long as the pipes are not excessively long.

Shower pump - pipe sizes

Looking to replace my existing gravity fed, positive feed, twin impellar shower pump it has inlet pipes of 22mm (to the pump) and outlet (to the shower) of 15mm. Will this pump be suitable?
Asked by: Janeo
Hi Janeo Yes, the Monsoon Standard Twin 3.0 bar should meet your needs very well. Just a couple of points to note: Firstly, a "Standard" pump requires a flow through the shower head due to gravity alone of at least 0.6 litres per minute. This is because a "Standard" (sometimes called a "Positive" or "Positive Head" pump) uses this flow to activate a flow switch to start and stop the pump whenever you start or stop your shower. Secondly, the Monsoon pump you refer to is supplied with flexible connection hoses with 22mm push-fit connections. These will connect easily to your existing 22mm pipes on the pump inlets. For the outlets you will need to use adaptors to connect the Monsoon flexible hose 22mm connector to the 15mm connection to the shower.

What is the difference between the MONSOON S and the MONSOON U apart from the price?

Asked by: Alspalsy
Hello! The difference between the Monsoon S (Standard) and Monsoon U (Universal) is essentially the mechanism that each uses to start and stop the pump as the shower is turned on and off. If the flow from the shower head is MORE than 1 litre per minute, due to gravity flow without a pump fitted then a 'positive head' situation exists and a 'Standard' pump type can be used. If the flow from the shower head is LESS than 1 litre per minute, due to gravity flow without a pump fitted then a 'negative head' situation exists and a 'Universal' pump type must be used. The flow can easily be measured by directing the shower head flow into a measuring jug and recording the fill level after 1 minute. If there is any doubt at all - especially if the shower has not yet been installed, opt for a 'Universal' pump type as it will work in either situation.
