What is Positive and Negative Head ?

Positive Head

This type of pump needs a minimum head pressure of at least 3ft 3ins (1000mm) between the base of the cistern and the shower head. This is because it relies on a gravity feed of water to kick start the impellers and start pumping hot and cold water. This type of shower pump ‘pushes’ the feed of water to the shower. See diagram for positive head shower pump.

Negative Head

In this situation the height between the base of the cistern to the top of the shower head is Less than the required 1000mm head pressure to trigger the pump - For example the cistern may be 500mm above the shower head. In this instance you will require a Negative Head Pump

Positive Head Pump

Ever wondered why your cistern is on a platform up in the loft ? This is to allow the minimum 1000mm head pressure to operate your shower. These days we don't have to build platforms in the loft when we use a Negative Head Pump.

Not sure which pump is suitable ? Send us a video of your hot water cylinder and location of your cold water storage tank ( above the cylinder in same cupboard or in the loft/attic ) Also a video of your existing pump if you require it to be replaced.

What is Up 'n' Over ?

Up 'n' Over means taking new pipe connections from your boiler or taps - Up into the loft and Over above new shower and down the wall connecting to the bar shower finishing in chrome pipe. Or if the shower location is on the ground floor the pipes would go up the wall then under bedroom floorboards and back down to bar shower where feasible. Extra charges would apply for under floorboard installations.

What is local to boiler ?

Local to boiler means that the boiler may be inside a cupboard next to your bathroom where we can go directly through the wall and pipe up direct to your shower, or we may draw off a new hot and cold from a hand basin or from under the bath.

We recommend fitting a thermostatic mixing valve to your EXISTING bath filler tap shower, this will be fitted to the pipes under your bath - Thermostatic mixing valves give a constant even temperature, also only the hot tap has to be opened giving the ideal set temperature every time. Supply and fit thermostatic mixing valve only - £249 When already fitting a pump. Must have access to pipes under the bath. 

Must be able to turn off hot and cold water supplies.

Alternatively we can supply and fit a new thermostatically controlled bath tap shower at the same time we fit your new pump - Taps here >
