Now install your water pipes to the 7800 bypass end connectors. Our preferred method is to
wrap the pipe threads with 2 or 3 wraps of Teflon tape, then apply a thin coating of white non-
hardening Teflon joint compound paste (available at all hardware stores) before attaching the
pipe fittings. Make sure inlet is installed to the 'In" pipe connector on the bypass valve and
outlet is on the “Out” connector.

Connect some flexible tubing from the drain connection on the 7800 control valve to a suitable
drain such as a septic tank or drain to a sewer. It is OK to run the drain line up and over the
7800 Birm filter up to 4 feet above the top of the tank. If the drain line will be more than 20
feet, and especially if your system is a 2.0 or 2.5 cubic foot size, use larger diameter tubing such
as ¾” or 1”. Note that it is desirable to be able to run the drain line into a bucket in order to test
the backwash flow rate in the future. This is why hard piping the drain line is discouraged,
however, if you do use hard PVC piping for the drain line, and you are able to remove the hard
PVC drain piping and attach flexible tubing should you ever desire for testing purposes, it is OK
to use rigid PVC pipe for the drain. Make sure the drain tubing is firmly clamped to the barbed
fitting with a hose clamp to prevent leaks.
