Review on 🚰 Laguna Brass 1201CP High Arc Swivel Kitchen Faucet for RV/Motorhome - Two Handle, Non-Metallic, Chrome Finish by Chuck Shapiro

After less than 1 year (and infrequent use) the hot water valve is leaking when the handle is in the "on" position. I removed the handle (small hex screw on the side) but don't know how to remove the part (and hopefully find a replacement) - the product description says it's a washer-less cartridge. The Revain page does not contain any manufacturer warranty information and I cannot find the manufacturer via a web search. I will contact Revain for a warranty return.
