I really appreciate the way you did this presentation. You said exactly what needed to be said and then backed up what you were saying. I am now well informed and have all my questions on this subject answered. Well done!!
Thanks explaining this and showing the results of your tests. I was confused about different opinion out there on ABS to PVC joints. Your explanation helped a lot.
Thank you for doing the different tests on the different pipes. the results show joining abs to pvc is not a "fatal" error and can be done in a pinch... very informative!!
Talked to a retired plumber at the hardware store and he said the same thing as you. Also he said you would basically have to repipe the house to get to code. It's expensive and he said he has not seen one failed.. So spot on..
I've used the green transition cement with no problems!! I've even used it in my own home. My drain pipes are ABS but I could not find ABS toilet flanges so I used a PVC flange and immediately connected it to the ABS. Been 7 years with no problems!!
With the ABS to PVC using the Oatey Green Transition Cement, did you use the purple primer just on the PVC or on BOTH the PVC and ABS. I have a broken ABS 3" to 2" Tee pipe inside a wall that has cracked. It's a wet vent stack with the 2" coming from a vanity sink drain into the 3" vertical vent stack. ABS is a difficult to get and PVC is both easier to get and stronger to boot, so I was thinking going this route. Thanks
Thanks for the informative video. I was worried about one connection I had from PVC to ABS for a shower drain. At least I know now that it should hold up
@StructureTech1 - Thank you so much for creating this video. Almost like Consumer Reports style of experiments with combinations of ABS and PVC parts (pipes and fittings). Quick question regarding the last part of this video where you had an ABS pipe joined a PVC coupler using purple primer and green transition cement... Did you use the purple primer on the ABS pipe or just on the PVC coupler? The instruction states just prime the PVC part and then use the transition cement for both PVC and ABS. Just curious. Thank you in advance.
I have a pool chlorinator with a 2" abs connect and have pvc pipe to glue it together. Do I need to use primer on the PVC side before glueing them together with the abs to PVC glue?
I'm just wondering what the actual justification is for prohibiting these connections. Aside from your testing which proved it's not a problem, if ABS cemented to PVC was so bad, then code wouldn't allow it at such a critical connection as a home's DWV system to the public sewer... 🙄 Under extreme conditions such as earthquake or structural failure, I would expect a Fernco to come loose well before a transition cement joint, no?
Great video! Audio and everything is great! Just tilt your cam down a bit. Simple rules of 3rd will make the video look more professional. But great info thanks
Wondering if the transition cement would be okay for a PVC Saddle Tee which is glued and secured with metal V-bolts on a vertical ABS sewage drain pipe.
(Early on the video I didn't watch the whole thing yet.) It depends on where you live, I can where I am but you need transition glue and you still need to use primer before applying the glue for the PVC and the ABS doesn't need the primer it can be just glue. It also depends what you're working on, ABS isn't fire rated unless you get the rated stuff which isn't common or cheap. PVC is self extingishing which is why its favoured more and for the price it isn't bad either. (End of video) OK, I can understand the reasoning and I am learning more about the code as I apprentance in my area of work. Great to know that as long as the instructions are followed then there's no real problem and it'll chemically fuse and melt as intended together.
Did you ever respond to a comment Re: 25 psi pressure or less it's ok per the standard (see text above what you called out)? So 25 psi is around 40 feet of water column. Your upper room would have to be 40 feet up before you violate this. Plumbing a first floor into the existing basement plumbing is only a few of psi ....no problem
Good information. ABS pipes and fittings are hard to find these days. I have ABS drains system in the house. I had to replace the sink and had to cut out the ABS trap leaving the ABS pipe sticking out the wall (none hub pipe). Based on code and this video, it is legal to use one of those Fernco style connectors to connect PVC to the ABS pipe if it meets code. Also, based on code, It is also legal to make a glued connection between ABS and PVC but only once at the end of a building drainage pipe and the beginning of a building sewer pipe (VA Code Section 705.16.4 Plastic pipe or tubing to other piping material). This is where I get a little confused and need help. To me it sounds like "at the end of a building drainage pipe" are the sinks, toilets, tubs etc. and the " beginning of the building sewer pipe" are where sinks, tubs and toilets connect to the building horizontal drain lines that drains into the main sewer line in the house. Am I correct? Or, are they referring to where the sewer system connects outside the house? If I glue PVC to ABS in this situation from the sink drain to the ABS pipe that leads to the sewer system am I within in code? I'd appreciate any insight on this.
@@Crustyfrank69 Nope. I was hoping this guy who knows this stuff would have answered my question. I searched Lowes and HD stores online and found 1.5" (10') ABS pipe at only 1 Lowes in MD. but no other ABS components. They had 13 and I ordered online for pickup to make sure I got one. They went pretty fast so there were others probably in the same boat. I found the traps and connectors on Amazon. They were price gauging, but still cost effective because I was stuck between a rock and a hard place. Check on Amazon. They have ABS components, but they were charging a lot for a small piece of ABS pipe and prices were always fluctuating, but that may be your only option. Good luck.
1/2 a small ‘detail’, the 1 that was tough to separate that you used purple primer with, did you put that primer on both the abs & the pvc?, or only on the pvc?- you’ve found what works, what was it(1/2 detail)?
Thanks a world for the info, I'm living in Quebec. I'm not a plumber, but I work in construction and I see most of the residential plumbing are done with PVC grey pipes. And sometimes for the small jobs I do for my self, I cant find transition materials from pvc to abs or vice versa in most stores such as HOME DEPOT, RENO DEPOT, RONA or fucking CANAC. most of the materials I find there are in ABS but not PVC grey pipes. I'm just wondering if ABS is so popular and very available , why the fuck they don't use ABS for all. I heard the PVC is more flexible and good for covering noise , but how come we cant find more parts in PVC in stores ? May be only fucking contactors are allowed ?
You're only talking about Plumbing Inspections. What about in other cases. Like 3D Printed ABS or ASA Parts to PVC Pipe or Fittings? Can you use Plain PVC Glue? The Clear stuff?
still I hand a plumber who I handed the transition stuff to but he used regular pvc cement(for pvc to abs fitting), he confidently said it wud work - but I donno if he’s the usual in this world👋😒
That’s for information I found this in a house I moved in to so I did it instead of spending a lot of money for a watching machine drain looks ridiculous dome
Thanks just made that leaky mistake in a tub remodel it's leaking just connecting abs to pvc to abs only one leaks but still it's a leak. Edited to clarify that the leaky fitting is a threaded female capture nut where you spin the female onto the male drain so I guess the torque involved broke the bond between abs and pvc not to mention it only had a 1/4" of abs into the pvc coupler.
