What ho one and all,

I posted some months ago regarding a 4" pipe kitchen waste blockage. I figured the 'fatball' was inside the ceramic U bend in the ground.

My tenant has cleared the blockage with a jet washer but I am going to do it again as I have a right angle fitting for car arches that will blast water directly into the U bend.

However, the owner of the g/f property where the issue occurs is quite adamant that I should get a 'professional' to investigate and clean / replace it properly, 'once and for all.' That is not going to happen unless he pays for the work, which would involve digging up a few meters of his patio!

My question is, what do 'professionals' use to clean a below ground 4" U bend? My drain shake kinda refuses to negotiated the bends, as does my 10m long sewer cleaning hose for the pressure washer.

Thanks and toodle pip

Thanks; pretty much as I thought but he is quite adamant that 'we need a professional' to tell him the same. WE certainly do not!

And maybe suggest not pouring fat/grease/oil down the drain.
