·         Cut pipe straight (very important). This will allow pipe to bottom into the socket.

·         Remove burr (shaving), use clean dry cloth or knife. Do not use abrasive material.

·         Clean pipe and fitting & ensure no dirt, grease or any other foreign particle.

·         Check dry fit. Pipe should easily go into the socket 1/3 to 2/3 of the way before any resistance is felt. This is commonly referred to as interference fit. If pipe goes to the bottom of the fitting without any resistance (interference) ensure fitting is of correct size. In case fitting is loose, change fitting.

·         Mark the socket depth on the pipe with a marker.

·         Apply a thin coat of cement into the fittings socket and a full even coat on the pipe till the mark to the depth of socket bottom. Do not puddles cement in socket use brush & dauber at least 1/2 the OD of the pipe.

·         For sizes above 2 inch AJAY recommends jointing with purple primer & Heavy duty gray solvent cement.

·         Insert pipe into the socket quickly while cement is still fluid (wet), if cement has dried, re-coat pipe and fitting. Twist pipe turn, this will allow cement to cover any dry spot. Make sure pipe goes all the way to the bottom of the fitting.

·         Hold pipe and fitting together (30 second) to make sure pipe does not push out.

·         Wipe off excess cement with clean dry cloth.

·         Allow cement to cure before pressure testing. Cure time is dependent upon temperature, humidity etc. however under normal conditions, allow 24 hours curing time.



All the Ajay Flowline Plus (brass / plastic) threaded Fittings must be used with a suitable thread sealant to ensure leak proof joints. Over the years, PTFE (Teflon or equivalent) tape has been the preferred thread sealant is still the most widely accepted and approved sealant. Some paste sealant can also be used, therefore only sealants recommended for use with CPVC by threaded sealant manufacturer should only be used.

·         Don’t use strings or jute to seal threads

·         Do not over tighten plastic threaded fittings.

·         Ajay does not recommend use of plastic threaded fittings above 600 C.



·         Prior to testing, safety precautions should be instituted to protect personal & property in case of test failure.

·         Conduct pressure testing with water only.

·         The piping system should be adequately anchored to limit movement. Water under pressure exerts thrust forces in piping systems. Thrust blocking should be provided at changes in direction, change in size and at dead end.

·         The piping system should be slowly filled with water, taking care to prevent surge and air entrapment. The flow velocity should not exceed 1ft./sec.

·         All trapped air must be slowly released. Vent must be provided at all high points of the piping system. All valves and air relief mechanisms should be opened so that the air can be vented while system is being filled.

·         Once an installation is completed and cured the system should be filled with water and pressure tested in accordance with local code requirements. However, care must be taken to ensure the pressure does not exceed the working pressure of the lowest component in the system (valves, unions, flanges, threaded parts, etc.)

·         Any leaking joints or pipe must be cut out and replaced and the line recharged and retested using the same procedure.



·         Certain precautions are recommended to be undertaken while installation of CPVC pipes with solar water heating systems and gas boilers.

·         Venting or Thermo-regulating valve: It is strongly recommended that Solar Water Heaters be installed with Thermo-regulating valves. However if no thermo-regulating valves are provided then providing proper air-venting on the hot water outlet side is a must.

·         SDR 11 Pipes only: Ajay recommends that only SDR 11 pipes be used with Solar Water Heater main lines.

·         Expansion and Contraction Loops: Based on the height of the building, it is necessary to provide expansion and contraction loops in case of exposed piping being used with solar water heater installations. The design calculations of loops are available on (p-14) of our product manual and depend upon the maximum estimated water temperature difference and the maximum length of run of the pipe. For detailed information on expansion and contraction loops. Kindly contact authorized Ajay representative.

·         Pipe Insulation: All exposed piping leading from Water Heaters including the down-takes (vertical risers) should be insulated. Even though CPVC has the lowest thermal conductivity amongst all alternate plastic plumbing systems, however to maintain thermal efficiency, it is recommended that the pipes be insulated. Nitrile rubber or PE foam may be spirally wound round the pipe to provide adequate insulation. For longevity, it is also advised to cover the insulation with aluminum tape for protection against water and sunlight.

·         Support Spacing: Ensure that proper support spacing (pipe clamp spacing) as specified in the Ajay Flowline Plus product manual (P- 12) is followed. At the roof level, in case at any point proper support is not available against the wall or the floor, bricks should be used to provide proper permanent support to the piping.

·         Brass Transition Fittings: Use only Brass insert type transition fittings for all connections with solar water heaters.



·         Avoid direct exposure of plastic piping to fire or flue gases.

·         Ajay recommends that CPVC be used after 10 ft. from the boiler before which metallic piping be used.

·         Follow all other precautions as listed above.




·         Use Pipes and Fittings from same manufacturer.

·         Install according to Ajay's Installation instructions and follow recommended safe work practices.

·         Keep Pipe and Fittings in original packaging until needed and store pipes in covered areas.

·         Take correct precautions while installing pipes and fittings above 2" in accordance with Ajay recommendations.

·         Remove dirt from pipe & fittings. Clean pipe & fittings with clean cloth.

·         Cut off min. 25 mm beyond the edge of the crack in case any crack is discovered on the pipe.

·         Cut the pipe as square (perpendicular) as possible before making a joint.

·         De-burr & Bevel: Ensure no sharp edges in contact with the fittings surface while inserting the pipe.

·         Take correct precautions while installing with solar water heaters & boilers in accordance with Ajay recommendations.

·         Ensure proper alignment of pipe & fitting to avoid stress on the joints.

·         Ensure installation is done in such a way that there are no chances of air entrapment.

·         Provide Vertical & Horizontal Supports as recommended.

·         Use Teflon tapes only as thread sealant.

·         Insulate hot water pipes exposed to the atmosphere.

·         Always conduct hydraulic pressure testing after installation to detect any leaks and faults.

·         Wait for appropriate cure time before pressure testing. Fill lines slowly and bleed air from the system prior to pressure testing.

·         Provide expansion loops on hot water lines.

·         Paint pipe (water based paint) exposed to sunlight.



·         Do not Use Metal Hooks or Nails to support/hold or put pressure on the pipes. Do not use straps & hangers with rough or sharp edges. Do not tighten the straps over the pipes.

·         Never expose the pipe to Open Flame while trying to bend it.

·         Do not drop pipes on edges from heights. Do not drop heavy objects on pipes or walk on pipes.

·         Do not use Fusion Compound for PVC or any other plastics for joining CPVC pipes & Fittings.

·         Do not dilute the Fusion Compound with Thinners/ MTO or any other liquid etc.

·         Do not use air or gases for pressure testing.

·         Do not use any other petroleum or solvent-based sealant, adhesive, lubricant or fire stop material on CPVC/PVC pipes and fittings.

·         Do not use CPVC/PVC Pipes & Fittings for pneumatic applications.

·         Do not use plastic threaded fittings for hot water above 60°C.

·         Do not thread CPVC pipes.

Ajay doesn’t recommend such mix-n-match combination. In case. GI is used in a Plumbing Systems. All the advantages of Ajay Flowline Plus will be lost because of contamination from the rust and other issues with GI pipes. UPVC pipes are not designed and cannot be used for Hot water distribution. Many times during peak Summer, water from the overhead tanks becomes hot. Sometimes even the back flow of Hot water from geyser can adversely affect the UPVC system. Further there is always a chance or the heating device {Geyser/ Solar Heater}, which may lead to failure of the system. Another issue is a chance the solvent-cement for CPVC and UPVC might get interchanged, which will cause system failure. In case. Lastly there is the problem of keeping inventory of different pipes, fittings, Fusion Compounds, installation tools and dealing with different suppliers, which will add to the cost



CPVC has been in use successfully for the past 40 years. Flowline Plus Hot and Cold water Plumbing System has been designed for a service life of 50 years.



CPVC has been successfully performing worldwide for over 40 years and Flowline Plus has a designed life of minimum 50 years. The system requires low initial investment and lowest installation cost and hence has one of the lowest lifetime ownership cost



Repairing of punctured & damaged pipe due to drilling/chiseling can be done by removing the cement plaster and using the pipe repair piece supplied by the company. Clean thoroughly the area of pipe damaged and make it dry. Apply solvent cement on the surface of pipe at damaged portion in the entire circumference. Also apply solvent cement on the inner surface of pipe repair piece and snap on over damaged area. Tie a small piece of string/binding wire around the repair piece and pipe for some time to allow to set. This is an unique system available with CPVC pipe where the damaged pipe need not be cut or shifted back & forth for repair. Do pressure test before re-plastering.



Ajay Flowline Plus solvent cement is tested and certified by NSF of USA. NSF stands for National Sanitation Foundation and works for development of public health standards and certification programs that help protect the world’s food, water, consumer product and environment.
