An improperly installed furnace lead to more plumbing problems than I’d like to have! The sink drains leak, the hot water supply line to the faucet leaks. The cold water supply line to the faucet leaks, the PEX fittings leak. The PEX clamps leak. I’m up to my eyeballs in leaks!!! Whats worse is the RV is 2 weeks old, the problem was caused by the factory installer and the RV dealership will not help me unless I bring the RV in so they can find the serial number on the furnace! BEWARE DOING BUSINESS WITH CAMPING WORLD BOSSIER CITY LA! You have been warned!
BTW, the serial number is under the exhaust panel.
