Most Affordable

Winterize RV Quick-Connect Plug

Sure, it’s affordable, but the Winterize RV Quick-Connect Plug is also environmentally-friendly as it does not use antifreeze.

Made from brass, it is also lead-free. Lead-free brass is harder, stronger, and more durable than regular leaded brass so this product can last a lifetime. And even though manufacturing this type of lead-free brass costs more to make, the company has decided to absorb the cost to keep their customers safe as an added bonus.

We also love this winterization kit because it not only works on recreational vehicles but also boats, watercraft, campers, RV waterlines, and travel trailers. It can even work on your sprinkler systems, drip irrigation systems, soaker hoses, faucets, pipes, spigots, sillcocks, water garden hoses, RV waterlines, and siphon hose bibbs where applicable. It easily attaches to the city water lines or a standard garden siphon hose, making for a quick setup.

• Affordable price point

Best Pump Converter

Valterra Lead-Free Pump Converter Kit

This lead-free pump connects inside the RV next to the RV water pump and automatically enables your water pump to winterize your water lines. The price point is middle of the road compared to the others on our list, but it is simple to set up and easily converts your RV water pump into doing most of the work for you, which is why it’s our best pump converter on the list.

Small and compact, this winterization kit is easy to store in any toolbox and take with you. However, many users have complained that it can be difficult to set up because it attaches to the water pump, which in some recreational vehicles can be hard to get to and a bit tight.

In this kit the siphon hose and the fitting is brass, so you need to be careful when attaching them. Some users have stated they wished both pieces were brass for ease of connection.
