Any mixer shower can be used with an electric pump from a gravity fed system to give higher flow rates and thus create a power shower. TAPNBATH.COM offer many pumps from manufacturers including New Team, Salamander and Stuart Turner giving a variety of pressures to suit bathroom requirements, thus a single shower can be fed or an entire bathroom suite if required. Pumps cannot be used with combination boilers, unvented or pressurised mains systems.

If you are in any doubt regarding your plumbing system see our Identify your plumbing system information page.

As a very general rule shower pumps and bathroom pumps are available to suit pressure ranges from 1.50 bar to 4.30 bar, with inlet and outlet connections of 15mm or 22mm (depending on model), they are suitable for gravity systems only and will require an electrical connection with a Double pole isolating switch. It is best to check the specifications for each item before you make a purchase as these do vary.

Points to note:

• Pumps can only be used in gravity fed installations
• Supplies to pumps should be dedicated and separate from other devices
• Individual pumps require a minimum head to operate automatically (varies from pump to pump, usually 200 - 300mm vertical distance from water level in tank to handset), if this is not achieved a negative head kit or negative head pump may be required
• Pumps will empty both hot and cold tanks more quickly than a standard system, please keep this in mind when selecting size of pump. You may want to check the capacity of both water tanks and think about how long and often the shower will be used
• Pumps must be installed to all relevant IEE Wiring Regulations (BS7671) and be protected with a Residual Crrent Device (RCD)
• A pull-cord isolating switch should be fitted, or a standard isolating switch which is out of reach of person using bath/shower
• It is advisable to fit easily accessible isolating and non-return valves to both inlets (where not already supplied). This will ensure future maintenance is made easy and compliance with Water Regulations. If in doubt consult your local water authority
