Lippert faucet leaks, replaced with Moen
poo
Lippert faucet leaks from cartridge. Plating in cartridge housing is flaking off and causing leaks around seals. Lippert would not fix this since their warranty is only 1 year. Replaced it with a Moen residential faucet and used sharkbite 1/2" to 3/8" faucet fittings on PEX water lines. This forum did not give me a field to enter conversation when originally posted.
