Water backs up into toilet
Hi,
I started renting this house in March and ever since I have had the same plumbing issue every other week. Basically every time I take a shower in the main bathroom it starts filling up with water and the toilet starts gurgling while water starts coming out from the base of the toilet and flooding the bathroom. Now in the other bathroom across the house, it has only done this once; however, when the main bathroom has this issue I can smell a sewer smell by the bathroom across the house. The landlord has sent a plumber out here numerous times. They snake the lines and say everything is good that when it rains it causes the city's main water lines to back up and there is nothing they can do. I just don't get how everyone can live like this; it's very frustrating and unsanitary! Granted just water backs up/comes out, but who knows what's in that water. Can anything be done? I can't take it anymore! Also, could this have something to do with the vent on top of the house (I live in Florida, not sure if that matters).
Thank you,
Elizabeth
