plumbing materials ?

this is the way I did mine with an external overflow. I came out of the overflow about 1 ft., I then put a t in the pvc. I went straight down to the sump from the t. With the horizontal section of the t I put a 4 inch piece of pvc, a 90 degree elbow up and a 6 inch piece of pvc (so at this point it's pointing straight up.) I took a cap and drilled a small hole in the cap and placed it on the end of the pvc that's pointing up. This allows air into the pipe and quietens the gurgling down a bit.

 

I hope that wasn't too confusing

 

i understand, ill try that thanks

 

I would do pretty much what was posted above But I'd toss the filter sponges totally unneeded and just trash and more work and cause /source of a problem .. The add a tee then a cap with a 1/8 in hole and if that is still making a sucking sound ? just insert a street 90 into the tees throat or center hole keep lines to sump as straight and direct as possible and making any right angle turns use long sweep waste fittings or 2 45's less back pressure and lessens the siphoning effects

 

I work on a golf course, and over 75% of my time is spent fixing irrigation leaks. What happened was 10 years ago the guys that installed all the pipes did so without using any primer, only glue... their logic was "you don't need to use primer on new pipe." Well, speaking from experience thats a load of BS. We get 2-3 leaks a week, all the same cause... leaking bell-house fittings, AKA where the two 20 ft length pipes are cemented together...all leaking for the same reason, no primer. Granted I'm dealing with very high pressure stuff here, and an aquarium isn't nearly comparable to that, but in my opinion with only experience to back it up, always always always use primer & glue. I will agree with Tangster in that the "Rain or Shine" glue, we call it blue glue, works best and is what I use on the fix jobs. It sets up very fast as he said, but is very very strong. It's up to you, but spend that extra few dollars on the can of primer, trust me you won't regret it.

 

thanks , i got the primer just incase, the purple primer.

one more question, i swear last one. were can one get acrylic from. do homedepot, lowes carry it. or do i have to go to a custom plastics place. i have a custom plastics place down the street, but im pretty sure they ask a fortune for cut acrylic.

 

Thats why by code we as plumbers can not use clear primer it has to be the purple stuff so when the inspectors look they see the pipe joints are all primed . The rain is shine has primer in it thats why it set up so fast and cost more.. ABS requires no priming but thats not ever pressure rated just DWV use only.. I guess the irrigation guys learned a lesson ? I have little use for that type of a crew had boy wanted a job and tried to impress me with his irrigation experience LOL They even use the thin wall stuff .. I'd never bury that .. Also thats why they recommend R&S for all the flexible PVC pipe the regular primer can mess it up under certain conditions with Temps and U/V lights outside in the sun.

 

All I have ever seen the have is the 1/8 ad 1/16 lexan window stuff at Lowes and H.D maybe your area is different ?

 

actually its best to to use a cleaner on all pressure lines oatey rain-r-shine calls for primer unless its a 4" or smaller non-pressure line. it has a 2 hour cure time at 60*f to 180 psi. but, that doesnt mean you have 2 hours to pull it apart lol like tangster said make sure u dry fit. if u want something thats really fast us ips weld on wet n' fast cure to 160psi in 10 minutes!!!!! home depot doesnt have it but almost all of your plumbing supply houses do
