Why SWR pushfit yellow seal advantage?

Tough and reliable leak proof joints: First time in India, advanced co-moulding technology at par with international standards. The Yellow Seal, consists of a plastic reinforced rubber ring which sits in the groove of the socket and is permanently positioned ensuring a 100% leak proof joint, unlike conventional rubber rings, which have a tendency to come out during fitment.

SWR Fittings

SWR fittings manufactured by Ashirvad pipes are available in both Pushfit and Solfit range. Each fitting is tested for pressure of 5 kg / per cm² before it leaves the factory to ensure that every joint gives you a perfect leak proof joint.


Installation Guide and Tips

·         Horizontal suspended pipes

·         As plastic is subject to thermal movement, we recommend that the pipe sockets are held firmly by brackets to prevent them from moving.

·         This ensures that any thermal movement is taken up in the expansion coupling, preventing buckling of the pipe between the supports. Please note that intermediate pipe brackets are for support only and must not restrict movement.

·         The British Standard BS EN 12056-2:2000 recommends that pipe should be supported at the following intervals.

·         Ventilation of Soil and waste System

·         Ventilation of a soil and waste system is necessary to prevent water seals in traps being broken due to negative pressure or pressure fluctuations within the system.

·         Broken seals permit foul air and smells to escape from the system, contaminating the air in and around the building. There are two ways of ventilating a soil stack, either externally to the atmosphere, or with an Air Admittance Valve seated in a non- inhabited space within a building.

·         The termination of an externally vented system must comply with the dimensional requirements illustrated in the diagram shown below.

·         Testing of System: A smoke test or water test is generally done to ensure SWR systems are installed correctly.

·         Water Test:  A water or hydrostatic test is generally used to inspect a completed plastic piping system installation and is the testing procedure recommended by Ashirvad. It is also the most recommended test in most plumbing code standards. The purpose of the test is to locate any leaks at the joints and correct them prior to putting system into operation.

·         Since it is important to be able to visually inspect the joints, a water test should be conducted prior to closing in the piping or backfilling behind the wall/floor.

·         To isolate each floor or section being tested, test plugs are inserted through test fittings in the stack. All other openings should be plugged or capped with test plug or test caps. Fill the system to be tested with water at the highest point. As water fills a vertical pipe it creates hydrostatic pressure. The pressure increases as the height of water in the vertical pipe increases.

·         Ashirvad recommends testing at 5m of hydrostatic pressure (0.5 kg/cm2) or as per the local authority’s guidelines. Filling the system slowly should allow any air in the system to escape as the water rises in the vertical pipe. All entrapped air in the system should be expelled for proper test result.

·         Once the stack is filled to desired level of water column, a visual inspection of the section being tested should be made to check for leaks.

·         If a leak is found, corrective actions must be taken up to find the cause of leak and to repair or replace the joint. Fifteen minutes is a suitable time for the water test. Once the system has been successfully tested, it should be drained and the next section prepared for testing.


Preparing the pipeline for test

·         All joints should be inspected to ensure the correct location of the mark or groove to the coupling socket.

·         Check that minimum cure time has elapsed since the last solvent cement joint has been worked on.

·         Check the tightness of all ties and clamps and correct positioning of piping.


Dos and Donts


·         Ashirvad Co-Molded Yellow Seal Technology (rubber ring) consists of 2 parts- rubber ring (black) which provides the seal tight joint and polymer (yellow) which acts as a retainer giving shape and strength to the ring. The ring will never fall off the grove when pipe/ fitting is inserted. Neither is it easy for the plumber to remove the ring by hand. The ring is made in our own factory and not imported. These rubber rings can be procured as spares.

·         Always encourage the use of lubricant while inserting pipe/fitting. This makes the fitment very easy and the pipe/fitting simply slides inside without much effort. The joint can also be made without using lubricant but the same becomes much harder.

·         The purpose of the lubricant is simply easy installation and is NOT a glue.

·         A joint made with or without the use of lubricant has the SAME pressure withstanding capacity/life/joint strength.

·         The greasy property of the lubricant lasts only for a few hours in the joint, after which it will dry up.

·         Ashirvad pushfit systems are tested to withstanding capacity of 5kg/cm2.



·         DON’T try to remove rubber ring from pipe or fitting.

·         DON’T install pipe in pushfit fitting without rubber ring by trying to apply solvent and thinking it will become leak proof.

·         DON’T Mix ashirvad pipe/ fitting with products from other players as fitment may not match properly leading to leakages.

·         DON’T Mix Pushfit fittings and Solfit pipes.

·         DON’T Use solvent for Pushfit joints.

·         DON’T Use lubricant for Solfit joints.

·         DON’T Cut pipe and make socket by heating and bellowing pipe mouth (manually at site). Buy and use only company made socketed pipe for installation. Ashirvad has the complete range 2ft- 20ft.
