Product details

The Pentair 190043 is the inlet pipe assembly for the PacFab FNS Plus DE filter. It is the genuine OEM part, supplied as a complete assembly.

What it does

The inlet pipe runs inside the tank and carries incoming water from the port into the filter body. Getting that water delivered where the design intends is what keeps the flow off the grid faces, so a cracked or missing inlet pipe shows up as grids that tear or blow out far sooner than they should.

Service note

Because the part is internal, the tank has to be opened to reach it. That is the right moment to look over the tank o-ring and the grid assembly, since the labor is already spent on getting inside.

Questions and answers

What people ask about this product, answered by our pool techs.

Which filter does this fit?
The Pentair PacFab FNS Plus DE filter.
Is this a genuine Pentair part?
Yes. It is the OEM assembly, part 190043.
What does the inlet pipe do?
It carries incoming water from the tank port into the filter body, so the flow is delivered where the design intends rather than straight at the grids.
Do I have to open the filter to change it?
Yes. The inlet pipe is internal, so the tank has to come apart to reach it. Plan on inspecting the tank o-ring at the same time.
