Are you wondering if line stopping and insertion valve costs are worth it? The actual costs associated with system shutdown include lab fees, the cost of treated water, the costs of advertising the shutdown, the costs of re-chlorination, and the loss of water revenue. Plus, there are the intangible costs, which include negative publicity, possible health risks and more. Valve insertion saves up to 100 percent of the costs associated with system shutdown. When shutdowns are avoided with Hydra-Stop, the cost of the valve is your only equipment expense.
