Yes, a leaking toilet can use a surprising amount of water.Make sure that the tenant is not putting one of those bleach tablets in the tank.

Don't use bleach.

With bleach.

On day one I took a garden sprayer and mixed a heavy concentration of commercial bleach and water.

I guarantee you, depending on the tenant, the invoice will be higher the there deposit, let them challenge it, they will lose every time.As per the urine smell, I bought a run down 8 unit apartment building, each unit was so bad the 1st thing that burned where your eyes, the 2nd was your lungs from the smell, each and every unit.Pull the carpet and padding, then go take a shower, its grouse, then wash walls with heavy bleach water, then pour and scrub heavy bleach water in to sub floor until it is soaked. open windows let dry and air out for a few days.

Do i bleach, replace, or hire a pro?

Spray bleach is a great solution to this "noisy fan".

A bleach solution will eliminate the problem.

Hi Gunnar, I wouldn't expect a lawyer was involved, because a lawyer would probably tell them that most mold is not toxic, that they should just get out their bleach, and just ask you to have someone check it out.I think you're right, that they may have some other agenda, like trying to get out of the lease.  

You’ve got a lot of folks from the suburbs coming in, expecting a bleached-clean version of a city where everything’s clean and the streets are free of any loiterers.
