Will it solve my problem?

And if so - what's the best location to install it. The PVC exhaust that
the washer drains into has a vertical part that then flows into a
horizontal part. Is better to install the check valve is far down the
stream as possible? or the other way around? or six of one?

another thought, unless your stated 'horizontal line' is on the ceiling,
all you have to do is get above it. *The washer will pump several feet
of head without problem.


He said about 18 inches below the ceiling. There is NO problem Just
install as I recommended in an earlier post, as advised by my plumber.

Curious. You see no possibility that your one plumber might have an
opinion that is at variance with other plumbers, equally skilled, or a
building inspector, who may be very skilled or not but still has the
final word?

This is the typical washing machine hose to PVC connector:

Note the little holes. You seem to be saying make a tight connection,
no venting/equalization holes, no trap, and call it good. You're
saying that a washing machine doesn't need a trap. If that were the
case, why would anyone ever put in a trap? It's obviously simpler to
do it your way.

I don't necessarily foresee any complications in use doing it your
way, but I don't see how it would pass code. Code calls for a trap.
Some people don't care about code, many building (and home) inspectors
do.

Just saying...
