What is interference fit?
Interference fit is the pre assembly test you apply to the pipe and fitting. After pipe is chamfered you will dry fit the pipe into the fitting and you will want resistance between 1/3 and 1/2 way into the fitting. This will allow for a good bond when cement is applied. If there is no interference fit, you should not try to cement the pipe and fittings together.
Are Oatey cements safe to use on water lines that carry drinking (potable) water?
All Oatey PVC and CPVC solvent cements have been tested to NSF standards and are approved with use on drinking (potable) water systems.
What should I do if there is a taste and odor in the CPVC water lines shortly after installation, how can I solve these issues?
Oatey cements and primers have outside lab approval for lines that carry drinking water (NSF). The plumbing system carrying the water should be drained by first shutting the water off at the water meter, which is most commonly found in the basement on the front wall facing the street. If you have a home on slab, it should be in the mechanical room with the furnace and water heater. Open all faucet valves and allow the interior piping system to air dry overnight. This will allow most of the remaining vapors from the cement and primer to dissipate and escape, air movement is a huge plus.
How long do you allow CPVC pipe to cure before introducing fluids and or pressure?
You can use the online charts to calculate the cure time for your specific application. Please review the documents below and read our blog for more helpful information.

Can you use All Purpose Cement when assembling PVC and ABS pipe?
No. Oatey has NSF approved cement for this application called ABS to PVC Transition Green Cement. This transition cement is for applications where the interior building drain and the exterior sewer drain are made of dissimilar plastics, generally ABS and PVC. Check with your local building officials before attempting this application to insure it is approved in your municipality.
What cement is used to bond flexible pipe and fittings?
Oatey Rain-R-Shine or PVC Flexible cements can be used for this application.
Does Oatey manufacture cements that can be used on lines which carry high and low pH chemical solutions?
Yes. Oatey Industrial Grade CPVC and PVC low VOC cements can be used in this application. Please contact the technical department for chemical compatibility for the cements that would be appropriate for the application.
Can I use Oatey CPVC cements for lines which carry Deionized water?
Yes.
What is chamfering the pipe?
Chamfering is the act of beveling the outside end of the pipe, which you will be inserting into the fitting. This keeps the cement from being pushed out of the fitting and causing a weak bond in the joint.
Can you use PVC cement to solvent weld electrical conduit?
Yes. The Oatey Heavy Duty cements can be used as long as the application instructions are followed.
