The Rothenberger RP30 (MPN 61130) is a compact, fully manual hydrostatic pressure testing pump built for quick pressure and leak testing of small-bore pipework and vessels in sanitary and heating installations — including underfloor heating circuits. It delivers a 0–30 bar test range from a 4.5 litre corrosion- and impact-resistant ABS tank, drawing 16ml per stroke through a steel mesh–reinforced test hose that keeps readings accurate even under sustained pressure. Light, single-valve operation and a footprint of just 440 × 200 × 240mm make it a practical bench-or-van tool for plumbing and heating engineers working in confined plant rooms, lofts and risers.

Pressure Safety

Never exceed the 30 bar maximum test pressure. Always release pressure fully via the shut-off valve before disconnecting the test hose, and wear eye protection during testing — a worn or damaged hose, fitting, or test point can fail suddenly under load.

Before You Order

The RP30 is rated for water (including drinking water) and Tyfocor. 420psi and 440psi for the bar-to-psi conversion — 30 bar is the figure confirmed directly by Rothenberger, so treat psi figures as approximate. Confirm you have the correct R1/2" BSPT male adapters for your pipework before the pump arrives.

Typical Use

The RP30 is sized for domestic and light-commercial pre-commissioning leak tests — new pipework runs, cylinder and vessel checks, and underfloor heating manifolds — rather than large-volume industrial systems. For higher test pressures or larger tank capacities, Rothenberger's wider RP and TP pump range (e.g. the lower-pressure TP25, 0–25 bar with a 7L tank) covers adjacent jobs.

Why It Works This Way

Steel Mesh–Reinforced Hose

The test hose is wrapped in steel mesh to stop it expanding under pressure. An unreinforced hose flexes slightly as pressure builds, which reads as a false pressure drop and can mask — or fake — a leak on the system under test.

Reinforced ABS Tank

The corrosion- and impact-resistant ABS plastic tank has a reinforced base, so it tolerates being set down on scaffold boards, van floors, and uneven plant room surfaces without cracking.

Single Shut-Off Valve

A single valve handles isolation, simplifying the fill-and-test sequence so there's less to get wrong when working solo on site.

Compact Footprint

At 440 × 200 × 240mm the RP30 fits where bulkier bench pumps can't — useful in loft spaces, risers, and tight plant rooms typical of domestic retrofit work.

16ml Stroke Delivery

A 16ml-per-stroke pump action reaches working pressure faster than smaller hand pumps, cutting the number of strokes — and the arm fatigue — needed to test larger pipe runs.

Wide Operating Range

Rated from 1–60°C, the RP30 stays usable across cold winter site conditions through to warmer heating-circuit test temperatures.

Frequently Asked Questions

What is the maximum test pressure of the Rothenberger RP30?

30 bar, adjustable in 1 bar steps, confirmed directly by Rothenberger's technical data for this model.

What test media can I use with the RP30?

Rothenberger's own specification lists water (including drinking water) and Tyfocor as approved test media. We wouldn't rely on it for oil-based testing despite some third-party listings suggesting otherwise, since that isn't supported by the manufacturer's published data.

How long can I test before refilling the tank?

The tank holds 4.5 litres, and the pump draws up to 16ml per stroke, so the practical run-time between refills depends on the volume of the system being tested and how much fluid is used purging air before pressurising.

What connection thread does the RP30 use?

An R1/2" BSPT male connection. Check your test hose adapters and pipework fittings are compatible with this thread before ordering.

Can the RP30 test underfloor heating systems?

Yes — it's commonly specified for pre-commissioning leak tests on domestic underfloor heating manifolds and circuits, alongside general sanitary and heating pipework.

How does the RP30 compare to other Rothenberger test pumps?

The RP30 sits in the lower-pressure end of Rothenberger's manual pump range. The TP25 covers a lower 0–25 bar range with a larger 7 litre tank, while higher-numbered RP models extend further up the pressure scale for larger commercial systems.
