My son moved into a house with overhead drain in the basement about 10 months ago. The line is just under 8’ from the floor with a brass check valve at about 4’ high. His 27 year old Kenmore has been working fine with it for that time. It does have a P-trap in the line where it connects to the main feeder.

This post is not a question.

What is the question? Because of thread drift, one cannot at all
assume the question is the subject line.

Assuming the subject might be the question:

My understanding is that washing machines will indeed pump 8 feet above
the floor but if you're not sure, get a guarantee in writing from the
store selling you the machine that you can return it for cash. Or maybe
one replacemen4t and cash if that one won't work. No extra delivery or
installation charge, in writing.

If you already own it, connect an output hose that goes 8 feet up and
then back down into the laundry sink or a big garbage can and see how it

I guess in his case there is no laundry sink or he'd just use that.

works. If it works, connect it permanently.


That only tests whether it can pump into that height for a moment, not
long term. As soon as the siphon effect starts, the pressure the washer
is providing drops again.

You have a point.

So make the output hose end just after it rounds the top at 8' and have
a second hose with a mouth big enough to catch all that comes out of the
first hose. That ends the siphon effect and more closely resembles what
will happen when the output is connected to the existing drain.

Or maybe just use one hose but put a substantial hole at the top, for
air, to end the siphon effect, maybe with a tube stuck in it to resemble
the air vent that all the drains in the house have, usually going up
through the roof. Of course if he's as high as the ceiling already, I'm
not sure where the tube will go. (It's purpose was to keep water from
splashing out of the hose. Otherwise a hole would be enough.)

I also see the hard-to-read subject line implies he wants to go more
than 8 feet high, to inside the ceiling. I guess he could knock a hole
where the hole will eventually be if this works and go up 8.5 feet for
the test hose.


I've mentioned in the past that the stream next to my house backs up
into the laundry sink when it rains the right way, so I have to keep it
plugged except when using the washing machine The 3 houses next to me
have the same problem. When my next door n'bor wanted to put a bathroom
in his basement, there is already (a light and) a drain under the
cement, but for some reason I looked into upwardly pumping toilets and
found that most washign machines also could go up 8 feet (and probably
8.5 feet.) His 27 year old kenmore does. So maybe he should write to LG
and ask them if 8 feet is the limit or what?
