Product details

This is the Waterway 873-E15S1, a 1/4 inch plug supplied with its O-ring. Waterway lists it for the SmartClean sand and Crystal Water DE multiport valve assemblies in both 1-1/2 inch and 2 inch sizes.

Where it goes

This is the small 1/4 inch port plug on the valve body rather than one of the main plumbing connections. Small as it is, it is a common source of a slow drip that gets blamed on the valve itself, because the O-ring hardens and takes a set long before anything else on the multiport wears out.

Fitting

Because the O-ring comes with the plug, the whole seal is renewed in one go. Thread it in and take it up snug so the O-ring compresses, then stop. The seal comes from the O-ring, not from torque, and leaning on a plastic plug is the usual way to crack the boss it threads into.

Questions and answers

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

Does the O-ring come with it?
Yes. The plug is supplied with its O-ring.
Which valves does it fit?
The Waterway SmartClean sand and Crystal Water DE multiport valve assemblies, in both the 1-1/2 inch and 2 inch sizes.
Is this one of the large drain plugs?
No. It is the 1/4 inch plug, a small port on the valve body rather than a main plumbing connection.
How tight should it go?
Snug, and no more. The O-ring makes the seal, and a plastic plug forced against a plastic boss is what cracks the housing.
