Most modern homes or homes that have been upgraded have Domestic water pumps. These can vary in strength and type depending on their usage and application. There are several different manufacturers of these pumps, usually 4-5 types in use in Ireland. Domestic Water Pumps are used where the usual gravity-fed water supply is poor and not suitable for good showers etc. Whole house booster pumps are fitted from the cold water supply connection in the attic. The Output of pump is then connected to a pressurised cylinder for hot water and cold feed pipes for the cold outlets. The use of a pressurised cylinder is a necessity due to the pump operating in the region of 3.0bar, this would burst a normal copper cylinder.
The most common Water Pumps in use would be:
