Removing a strap on boss - solvent welded

[mouk]

I need to remove and replace a boss which is solvent welded on.

I have seen advice on the net that for solvent welded ones you can try using a chisel and a heat gun.

Has anyone managed to do it successfully without ruining the pipe?

Also I would image the solvent weld originally would have damaged the pipe - how do you clean the pipe up to make another connection? Sand paper?

 

[rules&rulers]

What size is the boss ? can you leave it in position ?

Tried that and gave up PDQ the plastic is welded together,you may be lucky thou.

If you get it off,then clean soil pipe with sand paper,consider a larger strap boss to cover any pipe damage and glue it on with gap filler,it fills gaps and defects.

just a standard size with a 40mm adapter - it is an OSMA one I believe

No it needs to come off but be replaced in place.

maybe i will try and demo it out on a scrap piece of pipe first and see what happens.

It's called solvent WELD for a reason - it's a permanent joint which cannot be unmade
