I've got a job with a saniflo that's not put pumping away, the cause of which being the waste pipe downstream of it being blocked. Not entirely, but only letting mains pressure through at maybe 1ltr/min say. It's run in copper right out to the stack as far as I can see, so it should be able to take a bit of pressure. I've disconnected the saniflo from the copper pipe so it's not involved and I'm alternating pouring drain acid down it (yes I know they won't recommend this) and linking it to the shower hose to run mains pressure hot water down it, which has improved it slightly but it's still clearly restricted.
I'm wondering if it's not a 'blockage' as such and more a build up of something restricting the size of the entire pipe, has anyone got any ideas of what to try and clear it with? Would it be scale, in which case I have DS-3?
Thanks for any help
