Tank bolts eventually rust out, and because the water to the tank is constantly replenished (unless the shut-off is turned off), this can lead to lots of water being put onto the floor (and flowing through flooring wherever it is not water-tight).

You want to protect the rest of the asset and spending money anywhere else without a water tight roof to protect it is a waste of money.2.

Because of shared wall and roof etc.....even potentially electric depending on how lines are run etc....can I make repairs as needed to both sides....common wall framing, roofing etc that need to be done to keep my units water tight and structurally sound and then put mechanics lien on that unit?  

Any leads on where I can get a boiler plate semi water-tight application like that to further refine?

I selected it based on the thick wear layer, water-tight field, the relative flexibility (to go over an imperfect floor), the floating system and not the least, the color option (lol).

Here are a list of things you should probably be checking quarterly to maintain a good safe unit that also appreciates.​Interior:​Exterior:​Holes in walls, ceilings or floorsInsect/rodent infestation (including bed bugs)Weather/water tight (weather stripping)Hot water (minimum temperature of 110˚F)Peep hole/keyless deadbolt lockMissing electrical switches or cover platesExposed wiringInoperable A/CInoperable Heating Water tight sink, water closed, tub or shower (missing tile, etc.)Water LeaksSmoke AlarmsImproper sewage discharge​High weedsLitter GraffitiJunk Motor VehiclesPot holes in parking lotBroken windows/doorsDecayed/exposed woodUnsound stairs, rails or balconiesTrip hazards Holes or cracks in wallsInadequate security lighting

Which looks better and is more air/water tight.

when it comes to shower enclosure I am looking for water tight.

The have overlapping sections that have factory glue on them so they appear to make a fairly water tight connection with each other.

Can you recommend me a service or real estate attorney that can help me make a water tight ( as a wrap) can possibly be?
