The drains from my house and the house next door connect/intersect before joining the main pipe, the manhole cover where they join is on the boundary between the two properties, both council houses.
Two weeks ago our toilet wouldn't clear when flushed and all of the plug drains in the house stank. Next door had the same problem. I rang the council who came and flushed the pipes out. The man who did it said there was a blockage in the shared drain consisting of wet wipes and tampons, he said that when he started flushing it through the mass seemed to come out of next door's pipe but also said he couldn't be certain and that if it happened again we would both be charged for the call out/blockage removal as it's a shared drain and therefore a shared cost.
I've been to the loo a few minutes ago and upstairs reeks of drains again and the toilet isn't clearing when flushed so I'm certain there is a blockage again.
Can the council really charge both of us when I know for a fact we're not causing the bloackage? I wasn't having a period when they were blocked last time and I'm not this time plus I use a mooncup so the tampons were 100% not mine. We do use wet wipes for the baby but they go in the bin along with the nappies and no packets of wipes, including cleaning wipes, are kept in either of our toilets so there's no chance the DC have mistakenly flushed any. I also have hotel receipts proving that the DC and I were away visiting family the back end of last week/this weekend and a work schedule showing that DH is working down in Manchester from Thursday until tomorrow so the house was empty from Thursday night until late yesterday afternoon when I got back. This is only the second time we've had a blockage and I'm presuming it'll again be down in the shared drain but next door has had blockages on their side of the drain (so pipe blocked before it reaches the shared drain) at least half a dozen or more times in the last year (they moved in a year ago). I don't even know if she would be intentionally creating a blockage, the pipes are rubbish anyway with slow refill on the toilet tank and poor water pressure, other neighbours have had problems with frequent blockages too but they're a mix of privately owned and privately rented so not maintained by the council.
