My house was built in the 1980s and when I was in my crawl space, having to replace the leaky check valve ( vertical orientation, right above the sump pit, then the drainage line turns horizontal leading outside ), I realized that my washer drains right into the sump pit and, of course, the sump pump then discharges it outside. ( This is perfectly legal and acceptable where I live )
I had to replace aforementioned sump pump about six months ago ( installed originally five years ago ) and I had read in another forum that, over time, lint in the washer drainage water, could be the culprit as to why sump pumps fail. Recommended solution: pantyhose over the end of the washer discharge hose. OK, that makes sense, so I will do that.
So my question is this: can I just route the washer discharge right into the sump discharge line, avoiding the sump pit completely, thus avoiding more wear and tear on the pump? It just seem redundant dumping it straight into the pit and then having the pump do more work. Presumably ( and I'm no expert here, obvs ), but I assume that would entail .....
- Join the washer drainage line to the horizontal sump discharge line using a wye fitting
- Join the sump pump drainage line after the sump pump's check valve
- The washer drainage line, before joining the wye fitting, will need its own, preferably, spring type check valve in a horizontal orientation
I would positively love any input that any of you may have on this proposed ( and possibly completely erroneous ) schematic. I have learned so much lurking in this forum and hope this all makes sense. Many thanks in advance. JW
