Anyone have any brilliant ideas about how to tee into a 3" PVC line with 4" corrugated drain tile?

Here's one that will feed 4" pvc. I'm sure they make a 3" version. If not you can get a 3 to 4 pvc adaptor.

Put a tee in the 3 inch line with a riser. You might be able to cut the back off the tee and fit it over the line and glue it on.

Your kinda doing it arse about face to what is common on the shelf to buy so keep it simple and reduce down to a 3 inch plastic line first and then the T in to the 3 inch will be easy.

Yeah, I know. Just playin' the hand I was dealt. This old house has been jerry-rigged for almost 100 years, so I'm constantly having to cobble together things in very untraditional ways.:sad:

Old houses are great in character until it's repair time lol....I would start with the T in the link and play from there...maybe a picture of the job at hand would help.

If this is what i think it is the 3 inch will push into the T and the 4 inch over the T if you know what i am saying....i have used similar before.

This might be just the ticket, Galvie. I could use band clamps to hold it on. Here's a pic of what I'm dealing with:

Use a flexible reducer 4 inch to 3 inch on the down pipe section...

And then use a 3 inch sweep pipe T to finish the job.

or vice versa using a 4 inch sweep bend and 2 x flex 4-3 connectors which ever is easiest to get access to i guess.

I went with one of these: http://www.homedepot.com/p/FLEX-Dra...MERCH=RV-_-rv_nav_plp_rr-_-NA-_-202745388-_-N

If possible, I subscribe to K.I.S.S.:

JPR, you might want to think about that set-up. In the above photo, if the drain line on the left gets clogged, the water from the downspouts will be forced into your foundation drain thereby defeating the purpose of the foundation drain.

I believe I would run another drain line beside the one that's there, or look for a back-flow preventer that will work on a foundation drain. I'm not familiar with a back-flow preventer on a foundation drain since they don't have much pressure, but you might be able to find one that will work.

Thanks for the tip Bob, but if that drain clogs, the next owner can deal with it. :wink:

That was a cheap solution .....I would before you back fill that with soil construct a cover to protect that flexi pipe....maybe use some bricks and a concrete slab on top then soil over the top.

Here in the UK i would have been forced by building regs to have done something along these lines with a inspection chamber...

That's a lot of work for a storm water drain!
