⚡ At a Glance
- • Sealing Performance: Tough PVC bladder creates an effective temporary seal when inflated via the fitted valve
- • Best for: Plumbers, maintenance teams and DIYers needing quick, repeatable drain pressure checks
- • Not ideal for: Permanent repairs or long-term pipe sealing where a fix rather than a test is required
Inflatable drain test air bag made from tough PVC, supplied with a fitted valve and a 1.2 mtr fitted hose. Designed for temporary sealing during pressure and leak testing.
Secure temporary sealing – With tough PVC construction
Tough PVC forms a flexible bladder that expands when inflated, pressing against pipe walls to block flow. The material resists punctures and repeated inflation cycles while retaining shape.
Reliable temporary seals make pressure checks straightforward and reduce water loss during tests.
Controlled inflation – With the fitted valve
Fitted valve allows regulated air entry and prevents sudden deflation during a test, so pressure can be held steadily. Valve design supports repeatable inflation and adjustment on site.
Accurate inflation keeps tests consistent, reducing false negatives and the need for repeat inspections.
Extended reach for awkward access – With the 1.2 mtr fitted hose
The 1.2 mtr fitted hose connects the inflatable bladder to the inflation source and gives extra reach from recessed or awkward inlet points. Hose attachment is ready-fitted for immediate use.
Added hose length helps complete tests in tight or recessed fittings without improvising connectors.
