I plan to use some flex PVC to re-plumb my hot tub. Of course, the couplings and such will be regular PVC.

Am I correct to assume that I use the PVC flexible cement on the flex, and regular PVC cement on the regular PVC? And I can prime both with the standard purple primer?

Thanks in advance !!

I recommend standard clear primer.

Heavy bodied pvc cement. Not the thin stuff that comes in the gold can.

Thanks Brian. I have 'medium' cement in the grey can, so I'll get a can of the heavy bodied stuff. Just to be perfectly clear, I apply the same heavy bodied cement to both the flex and the standard PVC?

How does the purple and clear primer differ? Just curious. I don't have many joints to glue and another can of clear primer is no big deal. Just trying to learn along the way.

Thanks again !

The purple looks ugly as **** when you're finished.

Medium bodied should do you ok.

If you have any way to heat up the area with all the pvc, then you should.... like a kerosene blower/heater thing. The pvc cement process does not like cold.

If you can't heat up the area, then you can do what I do... I heat up the components with a torch (AT A DISTANCE!!!) to warm them up prior to applying cement. But with anything potentially dangerous like this, (flame and pvc cement) you must always follow appropriate safety precautions.

Yes apply to both components. Do it quickly... assemble and twist if possible, hold the two components together for about 10-20 secs to prevent them from pushing apart.

thanks brian. I don't have a portable heater, but it will be around 70F when I do the work, so it won't exactly be cold. I've had good results with my sprinkler system at these temps so hopefully I'll be ok.

Thanks again !

70 is like perfect for pvc stuff. Just let it sit for at least an hour or two (12+ is best) prior to using it.
