Do we use a glue or cement to join 2 PVC pipes. Its for the reticulation system which will be underground.
Bostik PVC Pipe Cement Green - Type P (Pressure) Fast setting, high bond PVC pipe cement for use in Pressure applications.
For bonding with PVC-U Pipes and PVC-U Fittings Suitable for pressure applications Suitable for use in contact with drinking water
No additives of any kind shall be mixed with this solvent cement. Priming fluids shall be used to prepare the jointing surface prior to the solvent cement application.
Is primer really necessary? Cleaning the joint with a cloth will work ? I checked and I can o my get 250ml from bunnings which I don’t think I am ever going to use. Seems like a waste for money ?
To put it in simple terms, the priming fluid sets up the PVC cement to do its job properly. The primer acts as a cleaner, removing grime as a PVC cleaner does, and it also softens the surface that it is applied on. PVC pipes are joined together through a change in their chemical composition.
(High) Pressure it likely matters, you want a strong bond. Stormwater/downpipes, probably not.
Not a plumber.
I just did a quick websearch for both these answers, try a deep dive on some Reno forums or similar, find a plumber or chemical expert as to why it’s important.
Another one:

You may as well just silicone the pipes together.
The primer softens the pipe to prep for the fusion process.
Without primer the glue is essentially just a gap filler.
That oatey cleaner you are talking about is for ABS pipe usually.
ABS doesnt require a primer but is often suggested to use that cleaner prior to application.
