Plumbing

[Steven Hedley]

Hi, I've recently had a plumber come out to my rental and tell me that it was mainly "wet-wipes" blocking the drain - he said that it was clear, and it should be fine now (after it was cleared). However, the blockage continued as it was, so he had to come out again and have a look the week after. I saw a lot of weeds/grass/etc be removed and exactly 1(ONE) wet-wipe. 

My question  is: Will I be expected to pay for the service? Shouldn't this 1 wet-wipe have been removed the first time? Also, wouldn't it be more feasible that grass/weeds/etc. was actually the cause of the blockage? As opposed to the 1 wet-wipe. 

Feedback/answers to this would be greatly appreciated. The rental is also very old, if that at all contributes to my question.
