MuPVC waste pipe should NOT be solvent welded to ABS waste fittings. Why?

[Ian101]

In reality though, it's done all the time. Most don't realise it shouldn't be done and the reasons why. So why?

What are the potential problems and the likelihood of those problems happening over time if an MuPVC to ABS joint is made and brought into service for hot and cold drainage?

Is there anything that can be used to joint MuPVC to ABS, to the strength and water tightness of correctly made solvent cement joints that is?

I was about to type a long answer to this but this website is essentially what I was going to say. It's an American site but physics and and chemistry is the same here...

I like that site because the author has actually done some simple tests.
