how can I unblock a 22mm narow bore saniflo pipe???
Discussion
Have had saniflo for all of 2 months. Worked great.
Recently blocked. Thought the pump itself may be blocked - so have opened it up, cleaned it out etc, only to find that the 22 mm outlet pipe must have a blockage - i filled the pipe with water and it overflowed instead of flowing.
There are NO vertical lifts at all - it goes down all the way. There are a few bends - but all are 135 degree bends.
I have tried some 3-core cable, but can only get it down about 40 cm.
I have tried a pipe unblocking hand pump to push the blockage thru with pressure - not work.
I have limited access in a ceiling void and as it is all solvent welded pipe, my only option will be to cut it, try to find the blockage in the void and then rejoin it with a straight coupler.
Any other ideas before I cut the pipe??

You need one of those spring things.
A pogo stick?
one of theseIf you have a way of making the end water tight try a jet wash ? I have done this at work before but as I say make sure you can get it sealed or you will get a back wash/spray from it 
Failing that you might get away with a drain rod without any of the connectors on ,but then you run the risk of just compacting the blockage further down the pipe,

one of thesecheers. I'm going to try the springy thing - I just tried good old fashioned lung pressure - after cleaning pipe etc etc. Not budging at all - more likely to damage my eardrums if I tried harder!
I was thinking mains water pressure - but if it blows off a connector in the floor void where I have no access, I am screwed!!

I see the problem with blowing. How about sucking? I was thinking mains water pressure - but if it blows off a connector in the floor void where I have no access, I am screwed!!

Well, I bought a spring steel pipe unblocker thing - 25 feet long with a metal soring thing on the end. Got through what seemed liek a difficult bit and could feed teh whole 25 ft in - and there is only about that much to the boss into the 4" drainage pipe. So I thought I had unblocked it - but it is still holding pressure!!
What the f
k!
