Test Equipment For Underground Sewer Systems

JDP offers a full range of test equipment for this purpose including the latest technology in super nylon. The inflatable and lever action test plugs in this section can be removed remotely without entering the manhole, the former can also be installed remotely - a great health and safety benefit.

Testing Bags

PVC Inflatable Testing Bags

Range available from 75 – 450mm Easily inflated air bag for trouble free testing of all types of pipe Inflated with a bicycle pump (available from JDP) Ideal for use in areas where access is smaller than the test diameter A large sealing area achieves a more effective test Testing Bags have a 1/2” through tube with a 1/2” BSP male thread Can be used for carrying out a water test, or air test using a ‘U’ air gauge Extension hoses are available to facilitate remote sealing

* Sealing Bags also available

Canvas Inflatable Testing Bags

Range available for pipe diameters from 50mm to 4000mm Ideal for use in areas where access is smaller than the test diameter Easily inflated for trouble free pipe sealing Inflated with a bicycle pump (available from JDP). Larger sizes can be inflated with a foot pump or small compresser Fitted with a brass air tap - for use with a brass inflator Larger sizes fitted with ball valve for inflating using a compressor Can be fitted with a pressure gauge to prevent over inflation. Extension hose available to facilitate remote sealing

Pipe Stoppers

Inflatable Pipe Stopper

Totally collapsible, lightweight to handle Available in size range from 300mm to 1800mm Manufactured to exact pipe size. Nominal bore + or - 6mm Car wheel type valve for air in vent, on/off valve for air out vent 5mm closed cell sealing surface, car wheel type - 1/4" BSP female valve for inflation and lever ball valve for rapid deflation Pre-set relief valve to suit stopper size connected by 1200mm umbilical tube. Pull out strap with hook and loop strip to attach U gauge

High Pressure Inflatable Pipe Stoppers

Wide expansion range will work in all types of pipe - 100mm up to 2,000mm Lightweight, most sizes can be installed by one person Reinforced synthetic rubber for maximum durability Available in Nitrile for Hydrocarbon applications Compressor inflation controller Special sizes upon request

Maximum allowable back pressure 3.0bar (30mtr head water). Maximum inflation pressure 6.0bar. Applies for stoppers fully inserted into the pipe and mechanically braced against slippage.

Test Plugs

Steel Test Plugs

Available from 40mm-450mm Roller bearings fitted as standard on all plugs 9" (225mm) & above to make tightening up of the plugs even easier. Zinc plated – corrosion resistant to 90 hours salt spray test. Combines the economy of price with the strength of steel

* Also available with lever action CAMSTOPPER® design

Aluminium Test Plugs

Available from 40mm up to 600mm diameter, larger sizes available upon request Roller bearings fitted as standard on all plugs 9" (225mm) & above to make tightening up of the plugs even easier Aluminium plates combine strength with lightness Chemical resistant seals can be supplied to order Steel components are zinc plated to 90 hours salt spray test

* Also available with lever action CAMSTOPPER® design

Multi-lock Steel Test Plugs

Multiple compression points around the perimeter of the plug enable the seal to expand in localised areas. Strength where it matters – at the compression point. Steel components are aluminium coated against corrosion The Plugs are fitted with handle bars, to make it easier to locate the plug in the pipe Can be supplied with twin outlets – lower outlet allows complete emptying of water from the drain before removal of the plug Chemical resistant seals can be supplied to order. "Double Seal" plugs can be supplied to order

End of Pipe Testing/Sealing Plugs

For temporary sealing of new pipework on construction sites Easier to use than traditional test plugs – fit flush onto the end of the pipe Available from 50mm up to 300mm diameter Zinc plated – corrosion resistant to 90 hours salt spray test

Bypass Test Plugs

Available as a CAMSTOPPER® lever action design or as an inflatable stopper. For use in sewer renovation or repair when it is necessary to over pump the flow. CAMSTOPPER® sizes 400 – 1000mm Incorporating a 4"/100mm or 6"/150mm Bauer connection. Inflatable sizes 100 – 1200mm incorporating 2"/50mm or 3"/75mm or 4"/100mm or 6"/150mm or 8"/200mm Bauer connection.

Camstopper Test Plugs - Nylon

The fast action lever modern design brings many benefits 20 times quicker to install and retrieve Non man-entry retrieval Improved sealing pressures Longer lasting durable pressures Labour cost reductions Allows improved compliance with Confined Spaces Regulations 1997

Test Kits

Camstopper Remote Installation Device

Non man entry installation and retrieval Stops flow in 4" & 6" pipes, up to 3m deep No confined space entry needed No contact with effluent or sewage

Air Test Kits

A basic air test kit for checking drains and sewers.

A range of test kits for drains & sewers in accordance with BS EN 1610 Air Test Kits contain 'U' air gauge, hand bellows, approx. 2m (6'6") rubber tubing, 13mm (½") nipple cap, 'Y' piece and full operating instructions

Smoke Testers

A smoke kit used for detecting broken or cracked drains

Smoke Testers produces a dense grey smoke for approx 4 minutes Use for detecting broken and cracked drains

Standards

All new drains and sewers laid in the UK must be subjected to an air pressure test in accordance with BS 8005. For sizes above 300mm in accordance to BS 8000 or BS EN 1610.

Tests should be carried out before back filling or bedding on or surrounding in concrete. Tests should be made manhole to manhole. The tests should be carried out by inserting drain plugs at each end of the pipe and assembling the 'U' Air Kit as illustrated.
Air is pumped in by hand bellows until the pressure of 100mm is indicated on the gauge. Provided the air pressure does not fall below 75mm in a 5 minute period, the drain is deemed to have passed the test.
