To protect your system from damage caused
by back pressure from hot water systems. You
should always have installed on the hot water
inlet an approved non-return valve.
NOTE: Always ensure hot water systems are installed in
compliance with manufacturers recommendations and in
accordance with all local regulations.

Connection of Mains Scheme or Town Water
Supply to either Suction or Discharge of Pumps &
Pressure Systems
Most Water Supply
Authorities have strict
regulations regarding direct
connection of pumps to
mains water supplies. 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.
