Abrasive Materials
The pumping of abrasive materials will cause damage to the pressure
system which will then not be covered by the guarantee.
For Automatic Pressure
Pumps Installed with a Mains
Pressure Hot Water System
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. In some
cases an expansion tank may be
required. Please consult local codes
for expansion tank requirements.
NOTE: Always ensure hot water systems are installed in compliance with
manufacturers recommendations and in accordance with all local regulations.
8
Models Maximum Inlet Pressure
BT14-300 60 psi
BT30-30 & BT20-30 50 psi
BT14-45 40 psi
BT20-40 20 psi
NOTE: The above pressure
limits also apply to well
pump boosting.
Connection to your Water Source
FLOODED SUCTION - FROM CISTERN OR
STORAGE TANK
Installations with ooded suction require a gate
valve so water supply can be turned off for pump
removal and servicing.
FLOODED SUCTION - FROM MUNICIPAL
WATER SUPPLY OR WELL PUMP
Connection of Municipal Water Supply to
either Suction or Discharge of Pumps &
Pressure Systems
Most Water Supply Authorities have strict
regulations regarding direct connection of pumps to municipal water supplies. In
some cases an isolating tank is required between mains supply and pump. Directly
applied municipal pressure can exceed pump operating pressure and damage
pump (see table overleaf).
