But most tenants will freak if you tell them you have this as no other landlord discloses because they don't test.If it had one of those really old gravity furnaces you should probably have it checked out as I know those had a lot of asbestos.

Besides possably being undersized with your heaters, gravity could be fighting you.

Take this thread alone; i read a person say another depression is soon to happen just because it's been a while from the last, inferring 08/09 as a depression.... never mind the obvious facts that there has been a grand total of 1 depression in the history of the us and 08/09 was not a depression but, fact's are apparently perceptual now, I am just curious if gravity is also just an opinion, lol.

They can ignore gravity but it won't ignore them.

You probably have a gravity system and it is pretty simple. 

To get rid of ground water, you can either provide a gravity drain to daylight, if it is possible and will drain, or you put in a sump pump.

I just want a nice way to illustrate the gravity of the situation.

Of course they are (and Gravity is the leading cause of airplane crashes too).But adding a few days to the process isn't going to solve that.Homelessness is caused by people not having a "Safety Net" in their personal lives, and by having borderline or no income.And by Section 8 not taking care of them in a timely manner, or at all.

I have a 4 unit (all 1 BR) that has a 1940's era "gravity hot water" boiler.
