Shower Pumps

These are used in homes where there is a low pressure of water. A shower pump can increase the pressure of the water, if and only if, the water supply is 100% gravity fed from a cistern in your roof space. If you have a large house which has 3-4 Bedrooms and more than 2 bathrooms then its best to install a Twin Impeller Pump, which can increase pressure of water flow in your entire bathrooms.

When do you need one?

Most electric showers already include a shower pump and you cannot fit a second pump to further boost the water pressure. You can use a shower-pump with a gravity fed electric shower with a cold water only supply, and also if you have a mixer shower, as long as the hot and cold water supplies are both (directly or indirectly) from the attic header tank. Bathroom taps are normally gravity-fed, so installing a shower pump is usually feasible; a plumber can advise if you are unsure.


What are Positive and Negative Head?

Most people need a positive head shower pump. This is designed to boost a weak supply; to improve a dribble to a usable water flow. If your header tank is above your shower outlet then a positive head pump is required.

Negative head pumps are only necessary if there is no water flow, when the shower is turned on. This usually happens when the shower is installed at a greater height than the feed tank, for example if you have installed a shower in a roof conversion and header tank is in its original position. If your header tank is below your outlet then you need a negative head shower pump.

What are the Advantages?

Shower pumps will give you an increased flow of water, but can never be used if your cold or hot water is mains-fed. They can turn a trickling shower into a power shower if your plumbing is suitable.

There are two main disadvantages to installing one.

  • Increase water usage
  • Emit some noise

Water use is going to become a major factor for everyone in the near future when compulsory water meters become a reality. More water of course means higher bills for heating as well as the increased water charges.

The noise of this product may be a deciding factor against buying one, especially if the house has multiple occupants who take frequent showers. The vibration can be reduced by installing the pump on a solid wall rather than a studded plasterboard wall.
