If you happen to have a 1.5 - 3 inch drain that somehow has become corroded despite the fact that water is being run down it constantly (meaning that's actually rare) then it's the landlords problem.

Depending on the area, the city may provide most of the utilities and in other cases they have to do multiple accounts. eg, one we're doing later this week: city provides water/sewer/garbage.

Find out how hard the water is and how often it needs to be checked and test as per EPA regulations..

Amazon Ebay.. all the time..I am talking furnaces, hot water tanks, lumber, light fixtures, drywall, siding...where you expecting to hear something different? 

It’s not the same as if the furnace or water heater stopped working.  

Within a week we had a major snow storm and water line froze and broke.

Is the outside structure damage from water , dry rot, or whatever.

I need to purchase a new furnace, AC and hot water heater.

I am not sure what you mean by private utilities, the park has to have water and electricity to the mobile home park.

That is why we have to water our foundations in droughts and landscape to water doesn't run into our foundation.
