I'm using Spa Flex and connecting to PVC , I sanded my PVC so that the Spa Flex would go all the way into the PVC, I will use PVC Cement and Primer in the PVC and Cleaner on the Spa Flex with a thick layer of PVC Cement?
I need some thoughts? Did I go wrong when I sanded the PVC?
and is PVC Cement good for Spa Flex in the long run {years}

{Oatey Medium.Clear PVC Cement}

Hi Ink,

IME/IMO no need to sand the pvc.

I do the following:

1. Wipe both parts with clean cloth.
2. Apply primer to both connections. I apply the primer to the spa flex as deep as it will go in the PVC connector. If you see primer, you know it may not be connected deep enough if this makes sense.
3. Apply glue to both sides.
4. Push together and HOLD for 15 seconds. Spa may recoil out of the PVC.
5. Wipe excess from connection. It will ooze out..

Remember that it is not really 'glued'. The glue causes a chemical fusing so to speak and the pieces fuse together.. Not glued so to speak. It better last years... I have connections over 1 year old and no issues so far.

I use heavy duty Oatey, but the med should work as well.

That's it.

Good luck.

I recently had to replace a swimming pool pump and redid some of the older 2" plumbing with flex PVC which may be the same thing. Sanding to fit will cause no problems at all, but you may find the adhesive adds a little lubrication which will make it unnecessary. Do hold firmly for a few seconds to let it set, or it will push right out.
