Description

The Pentair SWN is an inline well molded in nylon with a 1/2 inch thread. It is the Brand OEM part, listed as Pentair part SWN.

What it does

A well threads into the plumbing and reaches into the water so that a stem or probe can read the line without the line ever being opened. The well takes all the water contact, which means whatever it carries can be pulled out later without draining the system.

Material and fitting

Nylon will not corrode in pool water the way a metal well can. Its threads seal with tape or paste and will strip if forced, so tighten to snug and no further.

Before you order

This is the 1/2 inch size, ordered by part number SWN.
