I suspect that the answer to this one is to buy a new one, but I thought

It has periodically slowed down to a crawl when refilling the tank, and

best, by turning the feed valve on and off, I have gotten whatever
seems
to be plugging it up to clear. That's happened a couple of times, but
now I
can't get it unplugged.

I can't find any specifics on the mechanism, just installation
instructions. Is there a way to disassemble the valve and fix the
problem,
or isn't it worthwhile?


Yes, it's worthwhile.
If it's an 400-A the black top twists off 1/4 turn (water off!!).
There is a replaceable "seal" inside. This controls the flow.
The part is readily available.
While the top is off, gently open the shutoff valve; a stream will
shoot straight up-this will flush any dirt out.

Flushed it out, got a new seal and it's fixed!

Thanks for the help.
