Problem: something in pipe to mains but could be non return valve as council installed them due to flooding a couple of years ago. Liquid passes through but would solids? Hard to imagine it wouldnt get stuck.
Background: just bought house, Toilet blocked shortly thereafter. After many trials unearthed piping some leaking at bottom of stack so broke it up to replace, found massively clogged with toilet paper and crap. Cleared all, cut clay pipe, now ready to fit new plastic pipes and rubber connectors. But wonder about the above. Want to avoid further work as it involves much digging up concrete and is on the street so if itvis probably an NRV and solids can pass through it, i'll install the new piping but will delay filling in until ive trialled it for a couple of weeks.
Any thoughts?
