Flexible hoses included

This shower pump comes complete with four flexible hoses, which are used to link your shower pump to both incoming and outgoing water pipes. These flexible hoses are anti-vibration which means the hoses are less prone to vibration from the pump, helping to reduce noise and prevent damage to the pump itself.

This shower pump is ideal for those who are tired of getting a dribble of water when they enter their shower when really they should be enjoying a powerful spray of water. If this sounds like something that you experience, this may be the shower pump you need. The pump feeds through the hot and cold water to deliver an equal flow, powerful yet relaxing. This pump should be installed on vented system and is best suited for both, negative and positive systems, meaning that you won't have to worry about it not being compatible with your plumbing system. This pump doesn't need a gravity flow of water to operate, therefore you don't have to worry about your shower being powerful enough. Once installed the pump will improve your hot and cold water supplies to your home, bathroom, kitchen or cloakroom.

    5/ 5

    Plumbworld had the lowest price on this Stuart Turner pump, and it was delivered very quickly. I wanted to replace a noisy pump, which had worked for 15 years before giving up. The plumber replaced this with a Salamander pump, which stopped working after 2 months!!. Although this is an expensive pump, it is well worth the money. It is completely silent in our bathroom, it works instantly and is adjustable. I can really recommend it.

    Well made and super quick delivery, works really well in boosting the water pressure to not only the shower but other outlets as well. A tad more expensive than others I looked at but in the end it does the job 100% so satisfaction guaranteed. Plus the immense satisfaction of a 5 year manufacturer guarantee so no need to look anywhere else.

    5/ 5

    This replaced an old Stuart Turner pump. OK, it's not that powerful, but it gives a great shower and is super quiet if you use the anti vibration mat. The last one was 17 years old when I replaced it, if this one lasts that long I'll be well pleased and it looks just as solidly built.

    5/ 5

    I’m highly deleted with this pump. I bought it to replace a very noisy shower pump which the neighbours could here. There was quite a bit of pipe work to change as this unit is quite a bit bigger than the old unit. It was well worth the hassle though, as it so quiet. A whisper in fact.

  • Steve S
    5/ 5

    Replaces a 2.5 bar pump that was noisy and eventually failed. This whole-house pump is so quiet and gives excellent shower pressure throughout house. Cannot fault it.
