The availability of fresh water is arguably one of the most appealing features of RVs. It means hot showers, delicious food, and using your private toilet – in other words, on-road comfort at the highest level. For this reason, it is crucial to ensure that the whole system is well-kept, and that everything functions properly. Checking the system beforehand is recommended to avoid any possible issues when you are parked in remote areas and far from a spare parts supplier. If you need to replace some fittings or valves of the RV's plumbing system, consider the Pro-Line trademark by BK Products.

Founded over forty years ago, the company sets the bar for flow control solutions in the plumbing industry. Pro-Line fittings include a vast choice of specialized connectors and valves to repair or upgrade home and RV plumbing systems. We offer a wide selection of brass, brass chrome-plated, and PVC valves. Common designs include washing machine valves, ball, and foot check valves. You can also find various connectors, adapters, and hose bibb locks to ensure that your RV's plumbing system works properly. As they say at Pro-Line, the quality of people's life at home or in an RV depends on the dependability of the plumbing system and the parts they choose.
