Important:

• All plumbing is to be installed according to state and local

codes and regulations.

• Water supply lines need to allow proper water ﬂ ow for each

ﬁ xture.

• Flush all lines of any debris before making connections.

• Do not use pipe sealant or plumbing grease on any ﬁ tting other

then the control stop inlet.

The Aquaﬂ ush valve is designed to operate under various

water pressures with a recommended range between 10 and

100 psi (69 to 689 kPa). Each Zurn valve is tested for proper

performance at the factory before being shipped. Consult the

product pages of the catalog for available ﬂ ow options.

Most low consumption ﬁ xtures (1.28 and 1.6 gallon) require

a minimum of 25 psi running pressure through the valve to

obtain proper evacuation. Please be sure to consult ﬁ xture

manufacturer on minimum running water supply requirements

for proper evacuation.

When installing your quality Zurn valve it is rec om mend ed that

to protect the polished ﬁ nish you do not use a toothed wrench.

This will cause gouges and scratches on your valve.
