Hydra-Stop’s equipment is perfect for when you’re lacking valves in certain areas and you want to avoid shutting down the entire water system. Their Line Stop Fittings allow us to isolate the section of the pipe we need to work on, which is extremely important when there are hospitals and nursing homes in the area. We made our initial purchase about 15 years ago and this year we invested in their Insta-Valve. Hydra-Stop provides excellent training and support.
