PVC extension question

[89th]

My sump pump discharge pipe on the outside of my house has a 1.5” PVC elbow like above. I’d like the add a flexible extension pipe (maybe 5 feet long?) to it so I can funnel the water into a drain nearby.

Question: what would be the best part(s) to attach to this elbow, preferably something I can remove prior to each winter?

For reference, the black corrugated pipe is what I need to connect to (insert into). Last spring when we moved in I threw a quick fix onto the discharge pipe using the lay flat tubing you can see macguyver’d here. It was meant to be for a few weeks while I was away but has done the trick until now where it’s leaking a bit.

Intentionally trolling for a copper, steel, PVC, CPVC, or PEX plumbing war? I hope this time it doesn't work. Your camera thread has done enough damage already.

Flex PVC. With a clamp.

You're welcome.

Cool thanks! And hopefully we have avoided the Great Pipe Material War that Horace was wary of.

If it were mine, I would put a T fitting on the black corrugate that allows you to dump into the top. Then put an end cap on the open end and find a fitting that works for you like a downspout adapter. Then you can bury most of the black corrugated and it will look a lot better.

Good advice, normally that would work but the existing black underground corrugated pipe (which I can’t remove easily) has a crack near the exposed end so I need to insert a (flex pvc?) pipe into it about 2-3 feet to bypass the cracked section. Appreciate the idea!

[Mik]

Just cut it out and replace it. Corrugated is cheap.

If you don't do it now, your wife will make you do it later. You want that crap buried.

I have seen mice get through the smallest gap in the sealant.

You will eventually get yard debris in the corrugated. If it blocks or slows, you'll be getting sump discharge right next to your foundation. Seal it and bury it.

I have sealed off the opening of the corrugated pipe, project done! Thanks again, good advice.

[Mik]

Pics please.

Probably all kinds of critters too.

I'll go and take a picture later... I used "Aqua-seal" tape to close off the corrugated pipe opening. Although to be honest, the opening has always been there for probably 15 years and leads towards a street drain about 30 feet away, but the idea of critters/debris getting in the pipe(s) there was inspiration enough to close off access.

Here you go @Mik

[Mik]

OK. But you'd still be better off to have it all PVC of some sort and fully buried. Not sure how long that tape will last.

Don't skimp on the duct tape. I've seen off-brand duct tape ruin more than one large construction project.
