Tips On New Installations
Tapping Into Your Water Source
Turn off the water at the meter. Cut into your household service line and install a brass
slip-type compression tee, after the meter. The cut can be done anywhere on the line,
depending on the layout of your system and the location of your first manifold. Unless
unregulated static pressure is over 80 psi, tap into the line before the household pres-
sure regulator. In freezing climates, you will probably be tapping into your source in-
side a basement.
Next, install a gate or ball valve to act as your system shutoff valve. House the valve
in a valve box for easy access in below ground situations. Once this valve is installed
and tested, the valve at the meter may be left open for water usage inside the house.
In freezing climates, your next step will be to install a manual drain valve so that the
water can be drained from the pipes between the zone valves and the shut-off valve.
Install Schedule 40 PVC, thick-walled pipe up to the valves. In basement installations,
you will need to drill a hole through the wall to direct the pipe out to the valves. For
convenience in "blowing out" the system for winter, access to the line by means of a
tee with a capped 1" riser may be installed at this point.
If a backflow preventer is to be used, install it outside at the proper height.
FLUSH, FLUSH, FLUSH. . .Turn on the water at the shutoff valve and flush the pipes
free of dirt.
