NP i hope you get a good grade or whatever on your science, Id love to be able to have a spudgun for a science project.

Hotrocks, if your doing the building, you better at least go read the solvent welding how to. If you don't do it rite, your going to hurt yourself and someone else!

read this and don't solvent weld before you understand it.

[super spuder]

yea. if you hit the teacher with flying pieces of pipe. you might fail.

[hotrocks]

yeah i read it...basically coat inside with primer (make sure you dont get the threads on the cans with primer) then do it again, then do it with cement, then put the pipes together and twist, then press for a minutes then let dry....and do it outside.....right?


Apply to both male and female parts avoiding contact with threaded areas. Mask the threads with tape if needed beforehand.

what threaded areas? on the pipes?

[pyromaniac]

if you have female threaded adaptors all you need is teflon tape. you dont need to solvent weld adaptors.

a 2" pvc ball valve would have horrible performance.Like less than 100 ft
I would suggest a 2" sch 80 pvc union for burst disks for the best performance possible. Plus its cheap!(15$ at the high end 8$ at the low end)
