Plumbing... Ooh, What A Palaver!

One of the worst things in addition to the above is cement based products- tile cement, grout , plaster etc. buckets , tools get washed out and the remaining water goes down the sink and settles in any low spots or where the pipe has insufficient fall and slowly solidifies.

I was told many years ago that the pipes in india are smaller than here in the UK and the reason they avoid blockages is their diet !

Probably because in India they don’t use toilet paper so don’t block the pipes and many toilets are a hole in the floor. I speak from experience.

Many years ago I worked for my uncle whom not only installed septic tanks and fields, but also pumped them. I did get to play with FE loaders, back-hoes etc, but s I was the smallest guy, I got the job of going into the septic tanks to clear out the bacon grease out of the inflow pipes in the non-functional systems.

It did take me a few years to figure out why my uncle kept asking me if "I was OK"

Many years later, a client had out in low-flow toilets, in their offices, only to have to get their sewer pipes cleaned out annually, as the "low flow" was "insufficient" flow to clear various debris from their pipes.

Now, I know I'm too old to die young!

Grease will cause a lot of problems.

It fills up the P trap. Very common, When I had a crew they knew not to flush thin set and tile grout down in laundry sinks or toilets.

A brief post script to my original post - following is a photo of my cracked 40mm waste pipe. I think @Bingy man may have offered the most plausible explanation as to cause. It was located quite close to the sink. So, more than enough exposure to chemicals and of course all that hot pasta water.
