new tenant plumbing issues

[Ron Singh]

So new tanent moved in couple weeks back, and today they reported that both toilets in the house are backedup and clogged. They tried plunging but no luck.

no kids, and he was swering that they didn't put toilet paper or anything which can clog.

its weekend and they feel plumber need to snake in from outside of the house.

bathtubs are okay but some glumping sound when shower in use, they said.

bath sinks are fine.

what do you feel, what could be the issue ? I was staying in that house for 3+ years before them, and had no plumbing issues.

So...get it done and pay the bill. You have no proof it is their fault. 

Send a real letter on paper with signature service stating that the line is now clear and any and all issues down the road are at their expense

I would strongly suggest having the line camera-ed to ensure there is no break or sag or any other issue with the line
