How to Transition from Metal to PVC the RIGHT way

Chris shows you the proper way to transition from Metal to PVC connections.

We are a distributor of pumps, packaged pumping systems, on-site wastewater treatment equipment, on-site wastewater treatment systems, and custom electrical control panels for water and wastewater applications, water well supplies, drilling supplies, and water treatment equipment.

Wow, this man knows his stuff. Nice insights and detailed knowledge.

[BenKistner]

Such good information here! I've been doing plumbing projects for years and can say that I've run into all of the issues he describes here.

Your right on the fist two fittings . I been transitioning into this type of pipe and yes I been discovering this things .

best well videos on the web. hands down.

These recommendations are extremely important and often ignored even by plumbers who should know better. Having just completed a water system for a well and filtration, we have had four leaks at transitions from PVC to metal. THe reason is because this sound advice was not followed. All such transitions will now be redone.

Great video! I wish everyone doing this kind of work would follow these instructions…I’ve found every one of these mistakes on my property from previous work😅

[woolval]

Excellent explanation. Thanks! Now I can plan my work with the knowledge that what I'm doing is correct. Well, at least one part will be correct...

With the ideal connection the nipple is longer than the male threaded x socket connector so the moves the stress point farther away from the metal transition. Good tip on the hose clamp on the pvc side of the pvc to metal connection.

Thank you, your information is very through and useful.

This helped me replace a leaking 1" PVC adapter that had sprung pinhole leaks at the seam.

Interesting, I have seen each of the failures mentioned here. Totally makes sense

[matttafakt]

I've done these in the past and wrapped the entire joint with liquid steel :)

Great ideas for my pull up bar extension :) diy gym for the back yard

Great way to meet code, buy using a male thread!
Under the uniform plumbing code, you can't joint plastic to metal because of the difference of materials will expand and contract at different rates, causing a leak in the long run. They do sell proper PVC to copper threaded adopters or even shark bites with a PVC to tube fitting.
UPC 605.12.3 Threaded joints "...female PVC threaded fittings shall be used with plastic threads only." doing this will also cause the pressure rating to be reduced to 50% per UPC 605.12.3

We like to use the Schedule 80 nipple for connecting our backflow preventers to the irrigation system.

Like all the other comments, great info for DIY people. Good to follow with the taping video, too

With 20 years experience I 100% agree with this video. Avoid male/female adapters if at all possible.

[GrouseHiker]

Your recommendation at 1:39 regarding the adapter made from a coupling and cut nipple is a great idea, but it doesn't seem to work for the Schedule 80 nipples I can find. The nipples all have casting protrusions and the exterior of the nipple is not true... they have a casting seam. I wouldn't trust these to seal properly to a coupling.

Edit: Happened to be in Lowes today, and found the 1 1/4" nipples seem to be cut from pipe while the 1" nipples are cast and have the seams and protrusions I mentioned above.

You can also use a mechanical joint like a Dresser coupling

My own preference would be to avoid, if at all possible, any metal to plastic transition which cannot be inspected. Personally, I avoid them everywhere I possibly can. Primarily, this is because metal and plastic have much different thermal properties and repeated changes in ambient temperature, over time, can weaken the joint and eventually cause it to fail.
