Best Chemicals For Partial Blockage.

[SimonG]

Never had the need for chemicals in the past but needs must with this one.

What's the best?

Have a customer with a bath and a shower that are draining slow. Not vent related and no blockages in the soil pipes.
It's push fit and inaccessible so don't want to push a joint off with the snake.
Suspect a build up of hair and soap.
Cheers.

Not one too harsh as it might damage the rubbers

Use a wet vac to hoover as much water out the drain as possible beforehand so it doesn’t dilute it

I have seen examples of it happening on push fit waste pipe never on solvent weld

I have used Drain Buster but find it won’t work unless it can get directly to the blockage.
There is a chemical that I have seen advertised that claims to be unlike other chemicals and pass through the water to the blockage. No idea what it is called
