Shower Pumps

Shower pumps are used in homes where there is a low pressure of water, and it can increase the pressure of the water, if and only if, the water supply is 100% gravity fed from a tank 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 to your entire bathroom. Many modern bathroom fixtures require sufficient water flow to functional well. So choose the right one, and boost water pressure and make the full use of your bathroom fixtures.




More Info

When do you need one?

Most 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, as it 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 flow of water into a powerful flow, 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.

Items ordered arrived promptly. Minor problem with one of the flexible hoses having a hairline crack in the plastic joint; replacement sent by return. Otherwise fine.

Pump supplied rapidly but when fitted one of the plastic push on connectors had a hairline crack causing a small leak. Replacement hose supplied with 4 days but plumber had to make return visit. Pump is very noisy however despite sitting on an insulating pad.

I purchased this unit to replace a previous 20 year old Aqualisa model. Unit arrived really quickly and was a great price compared to direct from Aqualisa. Installation did require some re-plumbing due to different positions of the inflow and outflow pipework. I am a DIYer and completed the job easily in around 2 hours. The unit is very quiet in operation (rubber feet help insulate any vibrations) and it provides great water pressure. It has been used now for over 6 months and absolutely no problems.
