primer on male and female ends then cement on one. The primer is to ensure both surfaces are clean and allow for a good bond.

I much prefer cement on both pieces. Press together, and give it a twist to spread the glue out completely.

X2 on Bills method. I've seen them blow apart when only one side was glued up. It was at 150 psi. though and it was 30 minutes after it was glued.

+3 on gluing both sides -- I tend to go one step further and use PVC cleaner as my first step -- thoroughly clean, let quickly air dry, prime both sides, let both air dry, add cement on both sides and apply the parts together :)

I like the cement on both, because it seems to go together "slicker". And, you get that twist that seems to spread the glue and lock it in place.
In any case, at reef pressures, it really doesn't matter much. Some of my drains aren't even glued.

Agreed -- the only thing I don't 'like' about gluing both sides, is the internal pressurized resistance you get when applying some parts -- after you apply and do your twist, you pretty much have to continue to hold in place for 30 seconds to a minute... otherwise the part starts slowly extracting itself.

I deleted my initial response because I spoke to my husband and he said: "yeah we did apply the cement only on one part because I didn't read the instructions until after we were done and then I was hoping it would hold anyway."
So my advice is: read the instructions on the little cans BEFORE you start. Apparently on the cans it says to apply both - the primer and the cement to each piece. ;)

If its a slip fitting -- yes... otherwise, you wanna smear on some standard silicone... I usually do a thin ring all the way around the first few grooves on the male side, along with a wider strip that runs the length of all the threads in one spot... Think, draw a thin circle of silicone, with a wide strip in one part... as you thread it, the silicone will fill the gaps and seal..
If its slip though -- just clean, prime, cement both sides and apply :)

I'm convinced that THIS and this alone is the source of 95% of the ultra-convoluted plumbing that you'll find in this hobby :rofl:

oh yea how long do i wait before running water?

Tue, 15th Dec 2009, 09:38 PM
12-24 hours is recommended... sooner will work, but I like to give it time to cure :)

I waited about 12-14 hrs before I started flowing water to leak test on my 75.. but truth be told, it should be fine sooner. Its the cautious in me -- after doing fiberglass for years, I just prefer to give solvents their time to settle.. :)

It may be a bit late, but when I do PVC work...
If slip x slip then...
-light sanding each side
-wipe both sides with moist cloth
-primer both sides
-glue both sides
-let dry/cure for an hour before use (longer if possible)
-go get fresh air, lol
Read the can on the cure time, different glues/cement take different times.
Let us know how it came out.

The cement is harsh on the nostrils. I can't be certain but I'm sure I lost a few brain cells on my last CVP boj%

That's typically the way the cans of PVC glue work, don't feel bad, lol.

Looks like your not the only one that doesn't read/remember directions :angel:
