Test bladders with bypass for tightness testing to DIN EN 1610
Do you need to test a pipe or sewer for tightness? The test bladder with bypass is the right tool for this: it is inserted into the pipe and inflated, seals the line, and through the integrated bypass simultaneously allows the test medium to be applied in a controlled way, without you having to remove the bladder. This lets you carry out the shut-off and the tightness test in a single pass. Our test bladders are variable and cover diameters from 70 to 1,200 mm, suitable for all common pipe types and equipped with a compressed-air coupling. As a manufacturer based in Bad Abbach, we build them ourselves, Made in Germany. Free shipping within Germany.

Tightness testing to DIN EN 1610 with the test bladder
DIN EN 1610 prescribes the tightness testing of sewers and connection lines with water or air, both for new construction and for rehabilitation. The test bladder with bypass is designed exactly for this: the integrated passage guides the test medium in a controlled way to the sealed line, so that you can build up the test pressure and document the tightness without releasing the shut-off. Through the compressed-air coupling, you inflate the bladder safely. This way you cover testing tasks from the small connection line to the large collector with a single bladder.
Test bladder, shut-off bladder or shut-off disc?
The test bladder combines shut-off and testing in one and is the flexible, pneumatic solution for pipe testing across a wide diameter range. If you only need to shut off without testing, you will find the right variants among our shut-off bladders. If you prefer a rigid, mechanical test, our shut-off discs with bypass are the alternative. For frequent testing in the house connection area, we also offer the house connection test set EN 1610 as a ready-to-use complete kit.
Frequently asked questions about test bladders
What is a test bladder with bypass?
A test bladder with bypass is a pneumatic shut-off bladder with an integrated passage. It seals the pipe and at the same time allows a test medium to be applied through the bypass to carry out a pressure or tightness test without removing the bladder.
What is a test bladder used for?
Test bladders are used for the tightness testing of pipes and sewers, for example to DIN EN 1610 on newly laid or rehabilitated lines. The test pressure is built up through the bypass while the bladder seals off the line.
Which sizes are available?
Our test bladders are variable and cover diameters from 70 to 1,200 mm. Each bladder serves a whole diameter range and is suitable for all common pipe types.
How does the test bladder differ from the shut-off disc with bypass?
Both allow parallel testing through a bypass. The test bladder seals pneumatically and adapts flexibly to the pipe wall, while the shut-off disc seals mechanically and rigidly. For flexible testing across wide diameter ranges, the test bladder is the right choice.
