Choosing the right pump - gravity fed 'vented' systems

Single Pump Head or Twin Pump Head?

The majority of pumps for boosting water pressure to showers or other appliances in gravity head systems are available with one or two pump heads.

'Single head' pumps can be used to boost either the hot or cold water supply, or in some circumstances the 'mixed' water supply. They can also be used in pairs if required.

A more economical and practical approach in most situations would be to use a 'Twin head' pump which can be used to pump both the hot and cold water supplies equally.

Single Pump Head

Twin Pump Head

Any application pumping the hot water only (use a 'Universal' type pump)

Pumping cold water to an electric shower

Any application pumping mixed hot and cold water, after the shower valve (use a 'Standard' type pump - sufficient flow due to gravity must be present)

Any application pumping both the hot and cold water supplies

For these systems, consider one of the following:

monsoon single (standard or universal)

showermate single (standard or universal)

showermate eco single (standard only)

techflo tp single (standard only)

For these systems, consider one of the following:

monsoon twin (standard or universal)

showermate twin (standard or universal)

showermate eco twin (standard only)
