Changing a Storage Tank

DennisWP

Any thoughts on extracting a 1000 gallon storage tank from an undersized penthouse located on the roof of a nine storey older motel and replacing it all the while keeping the hot water system in service?

Before you pull the trigger....

DO you actually NEED 1,000 gallons? If its an older building that has undergone energy conservation, the load may dictate a smaller tank.

Whatever the storage capacity comes out to, I would recommend replacing it with multiple storage tanks, piped in parallel. Design and install them like batteries, so if one fails, you can valve it off, pull it out and replace it without shutting the system as a whole down.

Regardless of what you decide to do, I'd recommend running the whole idea past a structural engineer and get his blessing/recommendations. 1,000 gallons is 8,340 pounds, PLUS the tank.

If properly designed, your "down time" should be minimal, probably not more than 3 to four hours, and then when you bring the new storage tank system on line, transition should be seamless.

Proceed with caution. You're dealing with some pretty hefty weight.

Battery idea sounds best, make sure you open a vent while draining, (Rivets?) What about Subbing out the demo to an expert. Can you keep me posted on this one?

How about a helicopter? It's either that or cut it up Pc by Pc and hawl it down by hand or push over the edge when no one is looking. Make sure you put a mattress on the ground to deaden the sound when it hits. Good luck.
