You can do a lot better than a piece of hosiery wrapped around the end
of your washer's discharge hose.
Any place that deals with agricultural spraying equipment will sell
"inline strainers" like the kind shown in the photo below:
Basically, you simply splice the inline strainer right into your
washer's discharge hose, and clean it every so often. To clean it, you
simply unscrew the cup off the bottom of the strainer and remove the
cylindrical strainer screen. Clean the screen in a pail of water, or
just let it dry out and brush the lint off of it with an old toothbrush
when it's dry, put it back into the inline strainer and screw the cup
housing back on.
The advantage of an inline strainer are many:
1. it has much more surface area than you'd get by simply putting a sock
over the end of your discharge hose, so you wouldn't need to clean the
strainer nearly as often.
2. the cylindrical strainers come in various mesh sizes and the wire
mesh is made of stainless steel, so each strainer will last much
3. You can buy replacement strainers as parts, so you can have one
inside the inline strainer while the other one is drying out for
You don't need to be a plumber to splice an inline strainer into the
discharge hose of your washing machine, and anyone at the agricultural
spraying store that sells you the strainer will also be able to supply
you with the necessary fittings to splice the strainer into your
washer's discharge hose.
If you choose the go the hosiery route, I'd use one whole nylon leg.
Drop the nylon into your washer's standpipe, fold the top of the nylon
over the top of the stand pipe so the nylon mesh is on the OUTSIDE of
the stand pipe and put a clamp on the stand pipe and tighten it up to
hold the nylon in place. I'd be concerned about using the nylon because
if it tears, it could end up clogging up that drain pipe. That would
never happen with an inline strainer. Also, if you get an inline
strainer with a transparent cup, you'll be able to see how badly the
strainer needs cleaning.
