We're laying a septic line and for some reason I can't get my second pipe to bond. It's 4" pvc so it's a bit heavy and hard to work with. I line it up to the fitting and my husband pushes it in while turning. Is there a better way? We're not pros but we're not novices either. We've done this many times with smaller pvc. Help!

As I've already said, we've done this many times before with smaller pvc. The first one bonded. It should go without saying, we know how to use the primer/glue. We know "how" to do this. We just don't know why this one isn't bonding.

Zonerider, thank you so much!!! It's VERY humid here today (raining off and on). Also, we didn't clean it enough after the first try so it's no wonder it didn't work after subsequent tries.

Hello,
What schedule of pipe are you using? Schedule 40? Usually if you don't get a bond on the first try, it's best to pull the sections apart and reclean them. Depending on the bonding agent you are using, you may have to use Naptha or paint thinner, or something else, a cleaner should be listed on the adhesive container. When I want to be sure only to have to make the repair one time, I pull the parts apart, wipe up all of the adhesive I can, use a cleaner safe for plastic, GOO GONE works well. Once the both pieces of pipe have been cleaned and dried, take a good piece of fine grit sandpaper and go over both pipes, make sure your get all of the way into the receiving pipe. Now, coat both pipes with PURPLE primer, go an inch beyond the area that will be covered when the pipes are assembled and let it dry. Recoat both pipes with PURPLE, make sure you don't see lighter streakes through the top coat, if you do, continue coating until even. Apply liberal amounts of adhesive to the male pipe and a thin coat of adhesive to the female section. Use a continuous circular motion and make the coat even, don't let it goop-up or puddle, rotate the pipes as you apply if necessary. After both sections are evenly coated, push and twist. You should feel the two pieces wanting to seperate. Smaller diameter pipes are usually held for appx. 30 seconds, but be prepared to hold a 4" pipe 40 to 60 seconds. You may have to hold an additional amount of time depending on humidity. If you have high humidity, it is very important to apply the adhesive quickly and seat the pipes as quickly. AS a final precaution, make sure that the adhesive you are using doesn't require you to allow it to set up for a minute or longer before you make the connection. There are products on the market that require either making quick connection or need to set-up before connecting.
I hope this helps, I'm in the middle of reblumbing my parents house.

Smaller pvc is much easier to hold and control. With all sizes, especially 4",you need to chamfer (or taper) the end of the pipe so it will go into the fitting. Make sure that your glue is fresh and not thick. That can cause problems like you described. Good luck

You don't mention the use of the plastic pipe cleaner and the glue--this glue compound actually makes 2 pipes melt into one pipe---you can't just push the pieces together --you have to use the two steps cleaner and glue. The purple cleaner is a cancer causer--USE GLOVES. The glue is a strong petro chemical mix. Hint_--they both come in separate little cans.

If you _are_ using the correct PVC glue, make sure it isn't really old - the solvent that is designed to dissolve the surface of the PVC evaporates. Once that happens, it's nearly impossible to get a good bond, or the bond will come apart easily.

Use a piece of sandpaper to rough up the surface of both pipes to be joined. Use a primer on both surfaces then coat both pipes with the glue. Put the pipe together and twist a little while you push it in. That should do it. good luck.

sand the fitting to build up a mating service
when you glue the fitting be prepared to hold it tight together for about 4 minutes or do as we do
wrap the pipe about 8 inches away from the fitting with duct tape after gluing wrap the duct tape over the fitting and back down to the same place the first wrap was

Get some glue made espcially for PVC pipe at Home Depot or Lowes.

If you are using the proper PVC Cement, this could not be happening. It melts and fuses the PVC permantly in a matter of seconds!

Is it p.v.c. (white) or a.b.s. (black) they take different glues and primers.
