H 26 holding tank pump out fitting

[Don Shirm]

I own a 1995 H26 with a factory installed Groco toilet. The waste pump-out fitting is on the port side. The cap says Taiwan on the underside. The threads on the waste fitting appear to be between 1 1/8 and 1 1/4. Could this be a metric fitting? I sail on Lake Roosevelt in Washington state. All of the pump out stations require a 1 1/2 inch thread. I know there are universal fittings. These are messy. I would like the positive threaded connection. Has anyone else had this problem?

1.25" is pretty standard on most boats

If you check the marine stores, it's hard to find replacement caps any more for 1.5". You don't have to settle for a neoprene "universal" fitting, though...there are threaded fittings available--SeaLand has 'em...and THINK they're shown in the WM or B/US catalog. If not, you can one (buy two...they're inexpensive, and you'll still have one if it gets dropped in the lake). Specificy 1.25", 11 TPI (threads per inch).
