⚠️WARNING: All Aqua Plugs must be properly installed and used only for their intended purpose of static and low-pressure testing. NEVER exceed 10 PSI when pressure testing with any Aqua Plug. Exceeding this pressure limit can cause plug failure, rupture, or serious injury. Debris or protrusions in the pipeline can damage a seal or rupture inflatable plugs. NEVER use an inflatable plug when its failure could cause injury or catastrophic damage, or as the only means of protection for personnel working downstream. NEVER stand in front of any pipe plugs (inflatable or compression) while the pipe is under pressure. Aqua Plugs are designed for TEMPORARY use only and should not remain installed for extended periods of time. Actual conditions vary so user must accept full risk and responsibility for the selection and use of any product. Please review our Warranty, Terms and Conditions.

Note 1: Aqua Plugs are specifically designed for static and low-pressure testing applications in pool and spa plumbing systems. These inflatable plugs provide reliable sealing for leak detection and isolation testing when used within specified pressure limits.

Note 2: We are constantly upgrading our products and while we try to keep the website up to date, it is possible more current specifications may be on a quote or confirming order. Images are typically representative and may not be an exact representation, especially of the item size.

Note 3: Always wear proper eye protection, gloves, and any other recommended personal protective equipment (PPE) when installing, removing, or working near pipe plugs under pressure. Additional protection such as face shields, protective footwear, and long sleeves may be advisable depending on the work site environment and risk of pressurized fluid release.
