Help with choosing the correct shower pump for the job.

A shower pump is probably the most important installation in a bathroom that you get right.

Bad installation can cause poor performance or even worse premature pump failure.

Shower Pumps Explained

Positive Head System fig1 Positive head pumps operate under positive head conditions and are suitable for installation into open vented hot and cold water systems. Positive head pumps require a minimum gravity flow of approximately 0.6 litres/minute.
Negative Head System fig2 Negative head pumps are fully automatic, will work under both positive and negative head conditions and are suitable for installation into open vented hot and cold water systems. Negative head pumps do not require a gravity flow of water to start the pump.
Twin Shower Pumps fig3a Designed for installation into both the hot and cold water supplies therefore boosting both.
Single Shower Pumps fig3b Designed to boost single water supplies: Premixed, Hot or Cold.

Pressure

Pumps are rated in ‘bar’ which is the measure of pressure – 1 bar pressure being equal to 10 metres static head of water.

The higher the bar rating the higher the pressure. The following is a general guide for applications:

Up to 1.0 bar pressure = Low boost

Up to 2.0 bar pressure = Medium boost

3.0 bar plus bar pressure = High boost
