Twin pumps are designed using the highest standard of technology to boost your water pressure of both hot and cold water supply to a single shower, bath, shower mixer or mixer tap. Put a stop to low water pressure with this pump. It is perfect for transforming your unsatisfactory shower into a powerful and invigorating shower that you'll never want to leave.
Positive Head
A positive head shower pump is designed to be gravity fed, therefor it needs a 'head' of distance (at least a metre) between the pump and the bottom of the cold water cistern. The gravity feed 'kick-starts' the pump, pushing water straight through to your shower.
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.
Where an open vented positive head system exists with a minimum gravity flow of 0.6 l/min, then the Monsoon Standard is the perfect solution.
Standard twin pumps are designed for installation into both the hot and cold water supply - boosting both equally.
They can be used to:
Boost hot and cold water services to the complete home, bathroom, kitchen or cloakroom.
Boost hot and cold water supplies to a high performance shower system.

I decided to bite the bullet and pay the money. I use the ST 4.0 to power two showers and it doesn't disappoint. It is still noisy however not as loud as my previous pumps. I guess you're never going to get a completely quiet pump. The power is great even when using both showers. This uses 22mm flexi hoses so may have to do a little plumping as most households have the copper ends reduced to 15mm. Overall happy and got it at a good price from plumb world.

I bought this to replace an old shower pump that no longer worked.
Plumbworld had this 4.0 bar pump in stock and at a very good price.
Delivery was very quick - I could have had it the following business day if I'd wanted. This is a powerful and quiet pump and well worth the price

We were told our previous pump was caput and we would need a new one. I researched and quickly found this was cheapest so ordered. Website easy to use, ordering simple and before I could blink it was on our doorstep. Thanks plumbworld.

Pump arrived within a day and on time. Price was way better than anywhere else - my local bathroom supplier quoted me almost twice as much as Plumbworld for exactly the same item. Quality of pump first rate.

Good price. replacing identical pump. New one slightly smaller footprint
Also, sounds quieter, but this may be partly the insulating base - optional extra.

Our old ST pump lasted 15 yrs, so it a very easy decision to replace it with a new one.
