Watco 38410-CP drain stopper

The Watco 38410-CP is a chrome-finished brass bathtub drain stopper designed for residential bathroom repairs or upgrades. It suits homeowners and plumbers replacing a worn foot-actuated assembly in an existing tub.

Requires 3/8 in cross-bar drain

This stopper only fits drains that have cross bars measuring 3/8 in diameter so the 5/16 in pin adapter can thread securely. Without that exact cross-bar size the part cannot be installed and will not seal.

Foot-actuated install with pin adapter

Installation is performed by threading the supplied 5/16 in pin adapter into the drain cross bars, then seating the round stopper body. The most common issue is discovering the existing drain lacks the required 3/8 in cross bars, which makes the adapter incompatible.

Questions about this item

How does the 5/16 in pin adapter work once installed in a real bathtub drain?

The adapter threads into the cross bars of your existing drain, letting you press the stopper down with your foot to seal the tub and press again to release.

What drain standard does the 3/8 in cross-bar requirement cap in practice?

It fits drains that have 3/8 in diameter cross bars; drains without those bars or with a different spacing will not accept the adapter.

What physical clearance does the round stopper need to sit and seal properly?

The 2 in diameter stopper sits on the drain opening, so the hole must be wide enough for the flange to rest flat and the pin adapter to reach the cross bars below.
