It's not recommended. The easiest thing to do is get some plastic fittings and tubing at your local home center to adapt the torch water connection to your garden hose. This will be a total loss system where you drain the water away from your shop. It only takes a tiny bit of water to keep it cool. Many commercial shops use this method.
