It is feasible to sign up with ABS come PVC, however it is only supposed to be done through a mechanically coupling, not glued. If you just came here for the answer, you can stop reading… but I think you want the entirety story, so here’s that.

You are watching: How to connect abs to pvc


There room two frequently used plastics for drain, waste, and vent pipes within of homes: ABS (black) and PVC (white, mostly). These 2 plastics are almost all that is ever before used in brand-new residential building here in Minnesota, and I suspect for the rest of the country as well. For many systems, a plumber will use one product or the other, yet not both. This makes every one of the relationships simple; the plumber uses a solvent cement (aka glue) made simply for the material, points stick together, and everyone is happy…

Until then the “handy” homeowner come along and messes it up.

The easiest ar to separate was the PVC to PVC without violet primer. Following was the ABS to PVC without violet primer. The ABS come PVC relations with violet primer were as solid as the PVC to PVC relationships with violet primer, if not stronger. That actually seemed to pull the surface of the ABS appropriate off the the pipe. The only link that refused to come apart to be the ABS come ABS; the plastic would most likely rip apart prior to that connection would fail.

Again, one ABS to PVC glued connection isn’t technically correct, however this connection is highly unlikely come fail. Ns think fail is close to impossible; if ns hadn’t used a vice, yes no way I could have be separated the two. Yes sir no need to lose sleep end connections prefer this.
