Site Testing Specifications

VIPSeal® standard, extra wide, wraparound, adaptor and drain couplings are designed to withstand air and water tests in the construction and testing of drains and sewers as specified in BS EN 1610. These tests are required as part of sewers for Adoption (7th Edition) and Approved Document H of the Building Regulation April 2002.

Note: When used in conjunction with a water test, the end stopper should be securely braced.

Designed for life

When installed correctly VIPSeal® couplings have a design life of 100 years – exceeding that of the pipe. They are suitable for use above and below ground usually without additional protection due to the high quality of materials used in their manufacture. In certain circumstances where high levels of chloride are present, either a protective tape or a coupling made from 1.4401(316) grade stainless steel will give satisfactory protection.

Sealing System

In order for a coupling to perform well it needs to maintain an adequate sealing pressure between the coupling and the pipe. This is necessary to resist internal and external hydrostatic pressure as well as root intrusion. With VIPSeal®, this is achieved by a relatively simple system of applying pressure to the elastomeric sleeve through the use of tension bands. The use of a heavy duty single or multiple worm drive allows the radial sealing force to be equally spread around the circumference ensuring optimum sealing performance.

Performance

Pressure Resistance

Correctly installed VIPSeal® couplings will withstand the following maximum pressures:

RangePressure up to
Standard couplings with or without bushes (VSC/VBC)2.5 bar
Standard large and extra wide couplings with or without bushes (VLC/VLCW/VBC)1.5 bar
Standard extra wide couplings (VSCW)2.5 bar
Wraparound couplings (VWRC)0.6 bar
Drain couplings (VDC)0.6 bar
Adaptor couplings (VAC)0.6 bar
