Will this City Water Adapter for Shurflo Faucet fit my Vanagon with an aftermarket faucet or only the stock setup?

This City Water Adapter for Shurflo Faucet is specially designed for Vanagons (1980-1991, all trims and both automatic and manual transmissions) that have been upgraded to a Shurflo faucet. It's also compatible with Westfalia, Campmobile, and Vanagon conversions using common Delta Six faucet replacements. It’s not intended for stock faucets, so please confirm you have a Shurflo or similar modern faucet before purchase for best fit and function.

How does the check-valve tee in this adapter kit protect my water system, and what does it mean for daily use?

The included check-valve tee is a crucial safety feature. It prevents high-pressure city water from backing up into your onboard water tank, protecting your system from leaks or overfilling. When you’re hooked up to city water, the in-tank pump won’t push water to the faucet—so you’ll always pull from whichever source is active. This means safe operation without accidental mixing or pressurizing the wrong part of your water system.

Can I install the City Water Adapter for Shurflo Faucet kit myself, and what’s included to help with DIY installation?

Absolutely! The kit comes complete with the city water adapter, check valve tee, hose clamps, and step-by-step installation instructions tailored for DIY Vanagon owners. If you follow the included guide, most installations take under an hour with basic hand tools. Handy tip: Make sure to verify your water lines are free of debris before connecting the kit for the first time to ensure optimal performance.

Does using this adapter affect my ability to use the onboard tank or pump? What if I accidentally run the pump dry?

When city water is connected, the adapter automatically directs water only from the city hookup—your onboard tank and pump aren’t being used. If you try to run the pump while the city supply is connected, it won’t push water, but the good news is the Shurflo pump is designed to handle running dry safely (per manufacturer certification), so accidental dry operation while on city water won’t cause damage.

How do I winterize my Vanagon water system with this city water adapter installed to avoid freeze damage?

Before freezing temperatures hit, just drain your water system—make sure to run your pump to empty the onboard tank and open the city water adapter to ensure no water remains in the lines or fittings. This helps prevent cracking or damage from ice expansion. The adapter kit’s robust construction will keep your Vanagon’s water system protected season after season when properly winterized.

Once you have updated your original (and failure-prone) Delta Six faucet with a modern, super reliable GoWesty faucet, grab this kit to enable the city water functionality. This special check-valve tee prevents the city water hookup from pressurizing your onboard water tank. The check valve that is in the hookup itself ensures that the water makes its way to the faucet, and not to the outside of your van when the in-tank pump is activated.

When you activate the faucet with the city water attached, it DOES NOT allow the use of in-tank water. You will hear the pump running, but don't worry: it won't damage the pump at all (we contacted the pump manufacturer to be sure!).

Kit includes:
• Adapter
• Check valve tee
• Hose clamps
• Simple installation instructions

Above and beyond always killer service and shipping. I ordered a faucet and installed it and the switch had a short. They rectified it by shipping a replacement asap. Never a bad transaction with them
