In most cases an isolating tank is required between mains supply and pump. Davey also recommend this method. Directly applied mains pressure can exceed pump operating pressure and damage pump.

Connection to your Water Source BELOW GROUND WATER SOURCES Whenever the installation position of the pump is higher than 1m (3.3ft) above the lowest water level, a foot valve must be used on the end of the suction pipe as illustrated in (C) below.
Allow water to flow for 10-20 seconds to expel air then close outlet. Never operate your Davey Dynajet pump for more than a few ® seconds without discharge flow. Maintenance The only regular attention your new pressure system requires is to check the pressure tank’s air charge every 6 months.
4. Motor not free to turn eg. a jammed impeller. 5. Internal motor fault. *NOTE: For protection, the Davey pump motor is fitted with an automatic “over temperature” cut-out. Constant tripping of this overload device indicates a problem eg. low voltage at pump, excessive temperature (above 45 C) in pump enclosure.
