I managed to get it all together and I think I got high from the fumes while doing it..... this stuff stttiiiinks! I even had the exhaust and windows cracked open. lol.
Any way I followed some advice on a youtube video on how to cement pvc pipe together, and I think it came together pretty well. The primer was purple and it made a bit of a mess by running down the lengths of some of the pipes so I went out and got some krylon fusion like most post recommended and spray painted it black. I finished it about a week ago, and today I put in the check valve and siliconed it. Now waiting for it to cure so I can do a test.... *crosses fingers* I hope it works!
Well I became impatient and couldn't wait for the silicone to fully cure, and i had to test it. lol
Good news is it works!
DIY PVC overflow
I'll probably have to re-silicone if it comes loose due to my impatience.
