Advice about a blocked drain please

[ABC]

I bought a house last year and had some building work done before moving in which included a new downstairs shower room with wc with the drain going under a new extension.
A couple of months after moving in the drain from this shower room (also serves the utility room) became blocked - I called the builder back who cleared it. After only 3 months it is blocked again - mainly only me living here and I don't put anything weird down the loo!

This time I have bought some rods to try and clear it myself. Working from the 'dry' end I have tried to clear the blockage but all I am being able to shift is what looks like garden soil and I'm wondering if the drain is damaged and just filling with soil - is that likely/possible?

I'm hesitating to call the builder again as I've lost faith rather (still have no building control certificate as building inspector not happy) and don't want to rush into getting in a drain unblocking company as I don't have much cash to spare.

Any words of wisdom welcome

they only way your going to find out if its damaged is to get a cam down and have an inspection done

Hi ABC and welcome to the forum , how long ago exactly was the work done as if there is damage then surely the builders garaunteed there work for a certain period ?

Get it inspected with a drain camera, any faults the builders liable if the work was completed recently

Thanks for your replies - drain cam sounds expensive but the only upside is the builders still haven't had their final payment as the Building Inspector still isn't happy
