Lubricate the by-pass valve o-rings on the pipe connectors only with some vegetable oil or silicone
grease and connect the bypass assembly to the 5700-E control by sliding the bypass valve firmly into
the body of the 5700-E. DO NOT USE OIL OR PETROLEUM GREASE ON ANY PART OF THE 5700-E
CONTROL VALVE. O-rings are OK to lubricate but not the main tank threads.
9.
Make sure the by-pass valve is in the bypass position (above) when starting the installation. Follow
the IN and OUT arrows on the bypass valve and control valve for proper connection of water piping.
Leave in the BY-PASS position for now.
10.
Now install your water pipes to the 5700-E 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 the inlet is installed to the 'In" pipe connector on the bypass valve and outlet is on the
“Out” connector.
Note:
Arrows on bypass valve should be visible from the top of the bypass valve.
11.
Connect some flexible tubing from the drain connection on the 5700-E 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 Softener,
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.
12.
Next, connect the solution tank to the 5700-E control valve with the black tubing, provided with the
brine tank.
