Quick overview
- Genuine Pentair Factory part 156355, the upper piping assembly for Triton filters.
- Triton commercial side mount Listed for the TR100C and TR140C side mount sand filters.
- Internal plumbing The upper piping is what carries water inside the tank, above the sand bed.
- Sand in the pool Cracked or separated internal piping lets sand past and into the returns, which is the fault most owners notice first.
- Supplied as an assembly Comes as the piping assembly rather than as loose pieces.
- A tank open job Fitting means emptying the sand and opening the filter, so plan on fresh media and fresh tank seals at the same time.

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.
