Difficult To Find Plumbing Pieces

[jlvs]

Hi, I've found nearly everything I need for plumbing our house but two items. I am looking for an 1 1/2" PVC trap adapter for that final connection between the sinks p-trap and the PVC drain pipe. The adapter comes with a rubber or plastic compression nut that tightens down around the p-trap outflow. This adapter glues to the PVC drain pipe. Also would like to find one way venting valve as I don't want to penetrate the roof tils for the vent. Any suggestions woul be appreciated.

I've never seen AAV's (Air Admittance Valves) over here. If you don't want to go through the roof, why not just exit through the wall at high level and then continue up and around the roofline.

Or get one sent over from your home country.

I recall a general hardware shop in Sukhumvit left hand side just before Robinsons as you walk up from Soi 11. Lots of this kind of stuff, widgets etc.
