If our apt flooded from the toilet,should the apt pay us for some things that were damaged like mattres etc?

our apt got flooded wit water coming from the toilet.i live in a fourplex and same thing happend to my neighbors,it happened thrice in november,everytime the apt gets flooded we always report it to the manager,they say they will fix it the first time then the second,the third time it happened it was way worse,the water reached our bedroom and since i sleep on matress only,my mattress got wet,my roommate who sleep off the floor got his foam wet,we also bought new bath rugs everytime after it gets flood,since it happend thrice,we threw several rugs already since its nasty to keep them,also we used our towels and blankets to absorb the water and now they are all thrown in trash, plus all the sacrifice of sleeping while smelling bad odor from water.so after the health dept got it fixed i went ot the apt office to ask if i can get some form of credit for all the stuff we had to buy and dispose later on, they said no since i shud have rent insurance,my point is all was their fault not mine

No luck. You should have renter's insurance...the land lord is only responsible for making sure that stuff works. You using your towels to clean the mess isn't the landlord's problem - you could have just tossed them in the washing machine. Having to sleep while smelling bad odor is not something the land lord would be able to compensate.

However, if the toilet keeps flooding, your landlord is responsible to look at it and get a plumber. If he hasn't then he may be responsible.

However, I wouldn't make a tizzy about the towels, because when it comes time to move, he might retaliate and be a jerk about giving you your full deposit back.

Demand a plumber, and if he doesn't follow through, I suggest moving...and buying renter's insurance.

(Really, in my old apartment we had water heaters. If the water heater in the unit above us froze/burst and water started leaking through into our unit, then we would get no compensation for damages to our unit without insurance. So, if you have valuables, then I recommend the insurance.)

Did not read your whole post, but the answer is NO. That is what RENTER'S INSURANCE is for.

Can you prove the water damage was due to negligence by your apartment complex?

Most toilets overflow due to tenants. You could have washed your towels and blankets. All complexes encourage tenants to purchase renter's insurance for personal belongings.

I don't think you'll ever get money for the items you trashed.

Nope. That's why you should ALWAYS get renter's insurance (I pay $17 a month for it). It's really inexpensive and it PAYS to have it.
