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 below).
Models
HS12-30HT1 & HS18-30HT1
HS12-40HT1 & HS18-40HT2
NOTE: The above pressure limits
also apply to well pump boosting.
Davey Water Products Pty Ltd can not accept responsibility
for loss or damage resulting from incorrect or unauthorised
installations.
Abrasive Materials
The pumping of abrasive materials will cause
damage to the pressure system which will
then not be covered by the guarantee.
BELOW GROUND WATER SOURCES
Whenever the installation position of the pump
is higher than 3ft above the lowest water level, a
foot valve must be used on the end of the suction
pipe as illustrated in (A). Ensure that the foot
valve is at least 1
1
/
feet below minimum water
2
level.
(DRIVEN) POINT INSTALLATIONS
When a Multistage Pressure Boosting System
is installed on a (driven or well) point, a check
valve must be fitted immediately on top of the
driven point itself, as shown in (B). DO NOT
INSTALL THE CHECK VALVE AT THE PUMP OR AT THE TOP OF THE WELL. DO NOT RUN THE
PUMP WITHOUT WATER. NOTE: Be certain to select the driven point to suit the well conditions and
regulate the flow rate from the pump accordingly.
