Hello! I just recently purchased a quantity of 4" PVC sewer & drain pipe to drain the water from my downspouts to a small drainage lake in my backyard. I asked the supply house for PVC pipe and fittings, but when I got home, I discovered that the fittings are stamped as 'styrene', while the pipe and pipe-downspout adapters are labeled 'PVC'. The glue that they supplied seems to be the standard glue that I've used for PVC in the past, but it doesn't say anything about using it for glueing Styrene. The supply house rep was new and seemed hesitant when I asked if the provided glue would work to connect the pvc pipe to the styrene fitting and he said that it would. I've found the same fittings in PVC at my local Lowe's, so I can use all PVC. I just wanted to know if Styrene can be glued to PVC and if so, does it take a more specific type of solvent weld glue than the general purpose PVC glue? Thanks for any info!

There are four types of plastic in general use. Black plastic, which is ABS,(Acylonitrile Butadine STYRENE) and white plastic which is PVC and CPVC,(Polyvinyl Chloride and Chlornated Polyvinyl Chloride) ABS is used for drainage. PVC is used outside the house for cold water feed from the pump or the meter Also drainage both inside and outside the house. CPVC is rated for both hot and cold lines and can be used to plumb a house on the inside and then we have Polybutylene pipe,(PB or Polly Pipe) which is flexible tubing on water piping.
I would use Oaty All Purpose Cement and purple primer to glue the joints. Good luck, Tom
