Step 4 · Assemble the Filter and Bypass Loop
It's best to assemble the filter and bypass loop before installing it. First, wrap the threads of the male pipe nipples with 3-4 layers of Teflon tape in a clockwise direction. Screw one nipple into the 'IN' port and one into the 'OUT' port of the filter housing, tightening them securely with a wrench. Attach the filter housing to its mounting bracket using the provided screws. Mount the bracket to a secure surface like a wall stud or floor joist. Now, build the bypass. This will consist of two tee fittings and three ball valves. Using short pieces of 3/4-inch copper pipe and compression fittings, connect the tees to the main line connections and then build a parallel line above or around the filter with the third ball valve in the middle. This allows you to shut off water to the filter and route it through the bypass for maintenance.
