I even ran a garden hose down the pipe and turned it on.

Then take your hose with a good sprayer attached and hose the mildew right off.

@Ibrahim S  know it as a sump pump. probably rent it from Home Depot or wherever.it looks kind of like a kitchen garbage disposal with a hose attached. works like a powerful vacuum. just run the hose to where you want the water to go ( choose wisely ) and plug in the pump.god knows why the water is there, that will be another issue.

And yes, it is common to have a leak originate in your unit, and flood out numerous floors below...I think my record is only six other units, but I have heard of even more extensive damage in local highrises.If you own a condo, you MUST replace washer hoses with no-burst stainless braided hoses, and not the cheap chinese ones either!

It has hose fed sink and power run with an extension cord from my basement.

Looks like you volunteering to get Hosed. 

Anything higher than $300-$400 on the first couple deals is just an attempt to hose the buyer that doesn’t read the contract.

I said, if my house is on fire and I have a garden hose around I think I knwo what I have to do..

My townhouse had some damage due to a leaking faucet hose.

Pretty easy.For electric:Turn off breaker, make sure power is off at water heater.Hook a garden hose to drain, open valve and let heater be draining.Disconnect power, 2 wires and a ground.Disconnect water lines.See if HD will give you a discount since your buying 4 of these.Once tank is drained removed tank with help from a friend or a dolly.Reverse the process.Don't turn power back on till tank is full of water.Check with your utility company to see if there are any rebates or incentives.I replaced the one at my VRBO lake house with a new water heater and my utility company sent me a check for $300.
