Overview
Construct the manifold system shown below, using only schedule 40 PVC pipe and fittings.
VERY IMPORTANT to always support the PVC manifolds or any long runs to prevent any
added stress on the filter bulkheads and glue joints. In general, use as short a length of PVC
pipe as practical, and do not add unnecessary fittings and elbows; this will prevent unnecessary
pressure losses and improve efficiency.

follow (See Figure 2):

Use a light coating of non-petroleum based lubricant, and slide the rubber gasket all
the way onto the valve body.
