SAGAR SWR System
SAGAR SWR systems includes following:
uPVC SWR Pipes
SAGAR uPVC SWR pipes are as per IS: 13592 specifications. They are available in type A and type B. They are also classified with the types of pipe end.
One end is plain and the other end has either sliding socket or grooved socket. Sliding socket end pipes can be joint with solvent cement forming a
permanent water tight joint and recommended for horizontal lines as these lines are mostly buried in the flooring while grooved socket end pipes can be
joint with rubber ring forming a detachable water tight joint which allows thermal expansion and contraction.
Advantages Of Rubber Ring Joint
- It can be opened and closed as per requirement means it is flexible joint.
- It permits axial contraction and expansion and also angular deflection.
- Using of pipelines is immediate after laying without any curing time.
uPVC SWR Fittings
SAGAR uPVC SWR fittings are as per IS: 14735 specifications. They are available in selfit type which can be easily joined with SAGAR uPVC SWR sliding
socket end pipes and also with grooved socket end pipes with the help of uPVC SWR Ring Seal Adaptor.
uPVC SWR Ring Seal Adaptor
SAGAR uPVC SWR Ring Seal Adaptor is specially designed to convert the sliding socket end joint to grooved socket end joint simply by snap fitting.
Rubber Ring
Sanitation lines are not concealed and are exposed to sunlight; hence there will be expansion and contraction due to temperature variations. Rubber rings
are used to accommodate these expansion and contraction. Rubber rings are available as per IS:5382.
Solvent Cement
SAGAR PVC solvent cement is to be applied for jointing sliding socket end pipes and fittings. It is also cost effective without affecting the performance.
Rubber Lubricant
SAGAR rubber lubricant is to be used to help easy insertion of uPVC pipes and fittings into rubber gasket. It also prevents growth of microorganisms like
bacteria, fungi etc.
Pipes should be stored on level ground with maximum up to 1.5 meter height. More weighted bundles should be stacked on the bottom. If the pipes are
stacked in rack, the spacing of the supports should not exceed 3 feet. Fittings should be stored in cartoons. Rubber rings should be kept tension free.
Rubber rings, solvent cement and rubber lubricant should be protected from direct exposure to sunlight and kept in proper ventilated area.
Reasonable care should be taken to handle the pipes and fittings. Throwing around or dragging or pushing or severe contact with sharp objects of pipes &
fittings should be avoided.
Support Spacing of Pipe Clips
For vertical lines, pipe clips should be spaced at intervals of 1 to 2 meters depending upon pipe diameter but for horizontal lines distance should not be
more than 10 times the outside diameter of the pipes.
Installation Methods
UNDERGROUND INSTALLATION
For underground installation, SAGAR uPVC SWR pipes should be laid in trenches. The trench width should be minimum pipe diameter plus 300 mm and
width should be 600 - 1000 mm, depending upon the pipe size and slope for gravity flow. Check the dirt is not entering from the joints and pipe lines are
not laid on submerged rock. Leakage testing is to be carried out before filling back the trench.
ABOVE GROUND INSTALLATION
Use pipe clips as mentioned in the topic - support spacing of pipe clips. Cleansing pipe and fitting with door should be used at proper places to provide
access for inspection and cleaning.
CONCEALED INSTALLATION
For stress - free concealed installation of drain lines, slots should be made in the wall or concrete avoiding sharp edges. To prepare good base for proper
cement fixation while inserting SAGAR uPVC SWR pipes & fittings into the slots without a cement base, apply light coat of SAGAR PVC solvent cement,
then sprinkle medium sized dry sand. Leave till dry. In case of jointing PVC material to C. I. or A. C. material, these process is to be repeated. Before
concealing the system, leakage testing is to be carried out.
By using Y or Tee fittings and repair couplers, subsequent branch lines can be provided to existing SWR systems.
Testing Before Use
All openings below the top of the section to be tested should be sealed hermetically. Then water level is to be increased up to minimum 3 meters height
above the highest point of the section being tested or height is to be raised as per requirement. Every joint should be carefully examined for leaks.
Joining Technique
Solvent Cement Application For Sliding Socket End
Cut the pipe from plain end, make its end square
Using a chamfering tool or file, the end shall be chamfered to an angle of approximately 15°, to the axis of the pipe.
Remove burr, wipe the pipe end and fitting socket to remove all dirt, moisture and grease like lubricants by using clean rag.
Check dry fit of pipe and fitting and mark the distance length of pipe which goes into fitting socket.
Apply even and heavy coat of SAGAR PVC solvent cement on the external surface of the pipe and medium coat to the fitting socket.
Assemble the cemented parts quickly up to the mark by twisting pipe 1/8 to ¼ turn . To avoid push out, hold the assembly for about 60 seconds. A continuous bead of SAGAR PVC solvent cement is the evidence of proper joining.
Rubber Lubricant Application For Grooved Socket En
Cut the pipe from plain end, make its end square
Using a chamfering tool or file, the
end shall be chamfered to an angle of
approximately 15°, to the axis of the
pipe.
Remove burr and wipe the mating
surfaces to remove all dirt and
moisture
Apply SAGAR rubber lubricant on the
external mating surface and rubber
gasket.
Check the proper mounting position
of rubber ring and push the pipe into
socket. Mark the distance of pipe
depth in the socket.
Withdraw the pipe from the socket by
approx. 10 mm away to allow for
thermal expansion / contraction.
Converting The Sliding Socket End Joint To Grooved Socket End Joint
Solvent Cement Application For Sliding Socket End
Clean rib of sliding socket end fitting and internal surface of Ring Seal Adaptor.
Ring Seal Adaptor should be snap fitted firmly over the sliding socket end fitting with a uniform pressure.The click sound of snap fit is the evidence of perfect assembly. If required, the Ring Seal Adaptor can be detached by following same reverse procedure.
Joining Technique Insert the rubber ring into Ring Seal Adaptor.
Maintenance
MAJOR
If the damaged portion is above 300 mm, cut the pipe in total length of damaged portion plus two times diameter of the pipe. Use two repair couplers and
both side chamfered pipe in such a length of cutting. Slide one repair coupler to upper pipe and the other to lower pipe. Place the pipe in the gap and slide
both repair couplers over the juncture in opposite direction.
MINOR
Cut a piece of pipe having vertically unequal half cuts and bigger length than damaged portion. Apply light coat of SAGAR PVC solvent cement around
damaged portion and inside of half cut pipes and stick it over the damaged portion. Before use, dry them properly.

Types Of Sanitation System
Two Pipes System
This is the best system and suitable for large housing schemes. Here, four different vertical pipelines in terms of two sets are to be laid, one is for draining waste matter and the other is for draining night soil. The silage fixtures such as baths, sinks and wash basins are all connected through the branch pipe to the vertical waste pipeline of 75 mm size and the soil fixtures such as latrines and urinals are all collected through the branch pipe to the vertical soil pipeline of 110 mm size. To prevent accumulation of foul gases, a separate vent pipeline is recommended to ventilate both these lines.
One Pipe System
This system is suitable for small housing schemes. Here, only one main vertical pipe line is to be laid which drains waste matter and night soil from the respective branches. Even though a vent cowl is provided on the top of the main line for ventilation, it is recommended to provide an additional vent line.
