Right I’ve got it working!It now pulls itself through a 4” drain. I’ve had about 30ft down a different drain so far.
Will let my dad muck about with it down the sewer, that’s 6” so might not pull well at all.
I have a Nilfisk pressure washer, it came with a drain cleaning attachment about 15 m long, It has no problem pulling itself forwards. What you do have to watch is pulling it out of the hole too far when its running.
Couple of boxing days ago we had had a big Xmas dinner the night before with all the family & the drains backed up big time. Out with the gear & blockage cleared in no time. Just thought i would go in from behind the house & clean that end too. The trap at that end is quite shallow & with the washer going full bore i pulled the hose out tht little bit too far. In an instant it had blasted the trap clean with most of it coming straight upwards. It was in my eyes, all over my glasses, up my nose & in my mouth. As i stood there spluttering & spitting out unmentionable brown liquid i was trying to wipe the inside of my mouth with the inside of my jumper. At this point my trousers fell down round my ankles. My son nearly died laughing. Even i had to laugh.
shhhh happensSaw something similar on TV a while back, one bloke had just put the jetter into a full manhole and the other guy turned the pump on early, cue massive brown eruption....
