## Features

- Package Contents: You will receive an antifreeze hand pump kit, which includes a red pump, a brass connector, a 31.5 inches long transparent hose, a 19.6 inches short transparent hose, and two clamps. With the kit, you can easily inject antifreeze into your RV's black tank, gray tank or city water system, effectively preventing freezing water lines during winter and extending the service life of your RV.
- Prevent Leakage: We provide you with 2 clamps to secure the connection between the pump and the hoses, ensuring that the hoses will not come loose and that the antifreeze will not leak, providing you with a better user experience. Note: after filling the city water connection with antifreeze, we recommend you turn on the faucet, as well as the flushing button for toilets and showers, ensuring that the antifreeze circulates through the entire water system of the RV.
- Easy to Use: Simply connect the hoses to the pump and secure them with the clamps, then connect the short hose to the interface on the black water spray pump of an RV, and manually operate the pump to transport antifreeze into the black tank(see instruction manual for details). Additionally, if you find the hoses too long, you can trim them to the desired length.
- Durable Materials: Our RV hand pump kit is made of high-quality plastic, which is highly corrosion-resistant, lightweight, and durable. The hoses are made of PVC material, which is soft, pressure-resistant, corrosion-resistant, and not easily prone to aging or cracking. This hand pump kit is an essential tool to prevent damage to camper water lines due to freezing during winter.
- Wide Applications: The water system antifreeze pump is suitable for RVs, campers, trailers and more. This kit helps you easily and quickly inject antifreeze into the black tank flush line or city water system, effectively preventing the risks of freezing and bursting of water lines due to low temperatures, and ensuring the normal flow and use of the water system.
