Can PVC cements be used to assemble CPVC pipe / fittings?
No. The PVC cements are too aggressive and will cause probable failure to the CPVC pipe and fittings and if it was used, the joints should be cut out and replaced. If CPVC cement was accidentally used to bond PVC joints, it would not be necessary to replace them but future joints should be assembled with correct cements.
Will using Oatey Green Transition Cement to join PVC to ABS meet plumbing codes standards?
Oatey has developed this cement specifically for this application and it is UPC and NSF listed. In saying that; we do recommend that you check with your local building officials and see if they have any restrictions on its use. The UPC and IPC codes are a minimum guidelines and each city, county or health department can set forth tougher guidelines which may prohibit the use of transition cement.
What should be done with a plumbing system that was assembled using the wrong solvent cement, i.e., CPVC cement on PVC piping, PVC cement on CPVC piping or ABS on CPVC or PVC piping?
We cannot support these applications although a semblance of a bond may exist. It is a violation of all plumbing codes to use cements not specified for use with materials it is being applied to for bonding purposes. These joints should be cut out and the approved transition fittings used to finish the application.
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.
