Changing push fit boss to solvent weld

[muppetman74]

Hi,

I'm currently DIYing my bathroom and have a soil stack with 3 waste pipes bossed into it (bath, basin and bidet) - all waste is currently push fit under the floors.

Before I tile the floor, I'm going to replace all the push fit waste with solvent weld - it's not leaking but seems prudent as it isn't well supported so will need attention anyway. I'm getting rid of the bidet so will purchase a push fit blanking plug to blank that boss off.

Question is - how would I easily change the remaining 2 push fit bosses to solvent weld? From what I've googled, it's likely the bosses are solvent welded onto the soil pipe so not sure how to remove without damage. I cant "just have a go" without a plan as the soil pipe has the other toilet connected to it further up so don't want to bugger it up! I appreciate I can connect the new solvent weld waste to the old push-fit via a compression fitting, but that seems like an extra joint for no reason?

Thanks.

If the bosses have push fit adapters you can replace them solvent weld adapters.

Any chance of a picture of the push fit adapter if it’s the type I’m thinking of no

Thanks for the replies - I'll lift the floor and take pictures later.
