She sold them a home with a faulty foundation, malfunctioning plumbing, and hidden mold behind a wall.

The process of winterizing will involve fully purging the home's plumbing system of water.

I have this on my lease: "Tenant accepts the cost of clearing the drain of any and all stoppages within the property except those caused by defective plumbing, tree roots, or act of Nature or God."

Got all my copper plumbing stolen.

If it is going down your plumbing system and clogs etc. that could be problemmaticI also hope you are on public utilities and not a well and septic.anytime you have more people coming and going it will increase wear and tear.

Also, there are common domestic hot water tanks (gas paid by the owner), and a single gas meter so all tenants' cooking gas is paid by the owner as well.

Plumbing?

Any help or advice would be much appreciated as always and hope you are all having a great Tuesday so far.Many thanks,A I would call the police next time you hear a potential domestic situation and get a police report. 

I do strictly HVAC so I'm not sure about plumbing.

What you can deduct are things like wiring, plumbing, window treatments, cabinets, windows, etc.
