Going to get some good seat time burying a few of these babies in the low spots and building a swale halfway up the hill to re-direct the flow which currently runs right down my bulkhead.
the input line should Dead end into the T so that the 2 drain feilds get equal water. your current setup will only divert water to the second field once the first one fills up somewhat.
no cleanout for the pipe? i would have incuded a T at the bottom of the gutter downspout for a cleanout
good point about dead ending the t connection, I'll have to think about opening that up and adjusting. The connection at the downspout is just pressure fit, i.e. no glue so easy enough to pop off for cleaning access.
I assume you mean the chambers. The chambers are from Infiltrator systems. they come in 4' sections. and the end units are seperate as well. Here's a pic of the parts. My units are each 3 4' sections and 2 end caps.
