Quick overview
- Plug and o-ring together The 400-6601 comes with its sealing o-ring, so you are not hunting for the seal separately.
- Universal 1-1/2 inch fitting Sized for the common 1-1/2 inch drain port found across pump and filter bodies.
- Waterway part Sold under Waterway part number 400-6601.
- The part that goes missing Drain plugs get set down on the pad at winterizing and never make it back, which is how most people end up here.
- Seals a weeping drain port A hardened or nicked o-ring lets a plug weep even when it is tight, and a fresh plug and seal stops it.
- Hand tight is enough Snug it by hand against the o-ring, since overtightening is what cracks plastic drain ports.

Product details
The Waterway 400-6601 is a universal 1-1/2 inch drain plug supplied with its o-ring. It replaces the plug that seals a drain port on pump and filter bodies once the original is stripped, cracked or simply lost.
Why the o-ring matters
The threads hold the plug in place, but the o-ring is what actually seals it. Once that ring has flattened, hardened or picked up a nick, the port weeps no matter how hard the plug is turned, and the usual response is to crank it tighter until the plastic gives. Fitting a plug with a fresh o-ring solves the leak without any of that.
Fitting
Check that your drain port is the 1-1/2 inch size before ordering, then thread the plug in and snug it by hand against the o-ring. A light film of silicone lubricant on the o-ring helps it seat and makes it easier to remove at the next closing.
