Hydra-Stop’s Line Stop Fittings allows us to accomplish what use to take a full day in a half day. Instead of having to install two sleeves we just need one with the insta valve. The process is much quicker when using Hydra-Stop’s equipment. We’ve been working with them since the 90’s and exclusively use Hydra-Stop’s equipment for our water maintenance projects. Their equipment may be a little more expensive but they use better materials than most which lends to the longevity of the equipment.
