About a month ago we noticed smelly water coming from underneath the gravel on our drive. Water company came out and unblocked it, saying there were baby wipes down there (neither of us have ever thrown wipes down the loo so not sure how they ft there). Fortunately they didn't charge us as they did the work while we were out so we hadn't authorised it :-)
It is now happening again. We categorically haven't thrown any wipes or fat etc down the loo or sink since they last came and I really don't know how it's happened again this quickly. It is definitely coming from the manhole on our drive - we get a small river every time we use the shower. Is there anything we can do or do we have to call them out again and this time pay the £90?
