As-Is House Purchase - Seller Misrepresented - Any Recourse?

[Tim Porsche]

Hello All, 

I am under contract to buy a duplex via a wholesale deal and have already given the earnest money deposit. The house is being sold as-is. I still intend to buy the house, but found out something rather annoying. The wholesaler and seller represented this duplex as having two separate water meters and two separate gas meters. I now come to find out that this is not the case, and it only has one gas meter and one water meter shared between both units.

My question is, since this is an as-is purchase, do I have any recourse in this situation? Basically, I'd like to ask the seller to give me a credit for the cost to submeter the gas and water lines during the sale. If he says no, is my only option to back out and lose the earnest money deposit ($6,000) or go forward with the purchase, knowing I'll have a $3,000 - $5,000 bill or more if I decide to do this later?

Thanks in advance for any guidance. If it matters, this sale is happening in Pennsylvania.
