Why is a Horobin drain testing kit essential for site sign-off?

It provides a reliable, industry-standard method for conducting air and water pressure tests on newly laid or repaired pipework, ensuring compliance with UK building regulations and site handovers.

What pipe sizes does this drain testing setup accommodate?

The comprehensive kit includes adjustable expanding plugs and bladders designed to seal standard domestic and commercial drainage lines, typically ranging from 100mm to 150mm diameters.

How do you perform a standard air test using Horobin equipment?

Invert the expanding stoppers into both ends of the pipe section, inflate or tighten to secure a tight seal, connect the hand pump and U-gauge manometer, and monitor for pressure drops over the required test duration.

Are Horobin drain test plugs resistant to site chemicals and effluent?

Yes, the test plugs and stoppers are manufactured with durable steel or nylon center plates and high-grade natural rubber rings designed to withstand exposure to wastewater, chemicals, and gritty site conditions.

Does the testing kit come with a protective storage solution?

The complete setup is supplied in a heavy-duty, portable carrying case that keeps all manometers, hand pumps, nipples, and expanding stoppers organised and safe from damage between jobs.
