Product Identity

The Watco 38516-CP push-pull tub drain stopper is a brass fitting with a chrome finish designed for standard bathtub drains. It includes a combination pin adapter that threads into cross bars with either 3/8 in. or 5/16 in. diameter. The unit suits homeowners or plumbers completing a repair, upgrade or direct replacement of an existing stopper.

Thermals Noise Power

This mechanical drain stopper has no electrical components, so it produces no heat, noise or power draw during normal operation. Its brass construction resists corrosion from water exposure and cleaning agents. The push-pull mechanism operates silently without any moving parts that require lubrication or external energy.

Upgrade Context

The stopper replaces worn, corroded or missing push-pull assemblies in drains that already have compatible cross bars. The jump is worthwhile when the existing drain body remains sound but the stopper seal fails or the finish deteriorates. It is not for drains lacking cross bars or those with thread sizes outside the two adapter options provided.

Questions about this item

How do I install the Watco 38516-CP stopper and which pin adapter should I use?

Remove the old stopper, then thread the included 3/8 in. or 5/16 in. combo pin adapter into the drain cross bars — the step most people miss is matching the adapter diameter to the existing threads before tightening.

What maintenance or replacement will this brass push-pull stopper need over time?

The chrome finish on brass resists corrosion, but the rubber seal underneath the stopper head will eventually wear and should be replaced when water seeps past the closed position.

What is the first limit that appears under sustained daily use of this drain stopper?

The push-pull linkage and pin adapter threads endure repeated mechanical stress; the seal typically fails before the brass body shows any wear.
