1. Cautionary note - some cyanoacrylics (at least the retail store variety) will soften and fail under long term water exposure, espec. hot water.

2. THREADED fittings work well with sealants, but press in fittings are marginal at best for use with sealants, you need some sort of mechanical bonding as well.

3. Melting different types of plastics together is generally NOT a good idea, especially since some plastics are not even intended to be melted (not sure if polyethelene is one or not) Hot glue is also not a good idea. Plastics should generally be bonded with a solvent type adhesive appropriate to the plastic type. The fun part comes when attempting to bond different types of plastic, as it becomes necessary to find a solvent that works on both types.

Hope this helps,
