Product details

The Pentair 156355 is the genuine upper piping assembly for Triton commercial side mount sand filters, listed for the TR100C and TR140C. It is supplied as an assembly.

What it does

The upper piping is the internal plumbing that sits above the sand bed and distributes water across it. Everything the filter does depends on that water being spread evenly. When a joint splits or the assembly works loose, flow short circuits down one path, the bed stops filtering properly and sand can find its way into the return plumbing.

What the job involves

Replacing internal piping is a tank open job. The sand has to come out, which makes it the right moment to put in fresh media and renew the tank seals rather than reusing tired ones. While the filter is open, look over the laterals and the rest of the internals, because whatever aged this piping has been working on them for the same number of seasons.

Questions and answers

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

Which filters does this fit?
It is listed for the Pentair Triton commercial side mount sand filters, models TR100C and TR140C.
Why would the upper piping need replacing?
Internal filter piping cracks, splits at a joint or works loose with years of pressure cycling. Once it does, water bypasses the bed or sand escapes into the plumbing.
I am getting sand in the pool. Is this the cause?
It is one of the two usual causes, the other being a damaged lateral or underdrain. Both mean opening the tank, so inspect the whole internal assembly once you are in there.
Is this a genuine Pentair part?
Yes. It is the Pentair OEM upper piping assembly, part number 156355.
