@@dan4659 as long as you got good slope to the sump inside yes

No we don't here in Saskatchewan, Canada

I would put gravel on top, the idea is to filter out the bigger fines from the backfill

30 years is easy to beat with PVC. That thin black plastic pipe sags over time and does not usually survive cleaning. Unfortunately, it often takes a change in building codes to force people to build things that last for generations.

@@vtrandal The material of the pipe is hardly the main problem. The only drainage that works easily longer than 30 years is having your house in a gravel pit or on top of some bedrock with slopes away from the house.

They can be built to last longer. It just takes more time, effort and attention. Using gravel, filter fabric and then 1&1/2" clean stone with smooth wall sdr35 or triple wall pvc with 1" pitch per 10' makes it last a long time and servicable.

@@johnjmariettijr5671 Only if you live somwhere where there isn't a lot of vegetation.. Otherwise you are bound to get stuff stuck in your drainage, gravel getting siltrd, roots growing in to pipes, ground shifting etc etc.

​@@vtrandal explain to me why it doesn't survive cleaning.

A bit more here, a bit more there. No one wants to hear it's cutting into their profits lol. Should be spec'd properly in the first place. This is standard builder fair and better than nothing. Lasts long enough that the homeowner forgets about the Builders' responsibility.
