Flushing Test

1 Toilet Paper Test

It shall then be flushed. This test shall be repeated four times and the pan shall discharge the full charge of the paper at last three out of four times.
2 Smudge Test
The whole of the interior surface of water closet to 40 mm below the flushing rim shall be smudged with quartz powder of contrasting colour passing through 1.18 mm IS sieve and shall then be flushed observing carefully the surface of the water closet during the flushing. Immediately after the flushing, there shall be no smudge left on the bowl.
3 Holding Capacity Test
The water closet when sealed at the outlet and vent (if fitted) with water-tight seal shall be capable of holding not less than 10 1 of water between the normal water level and the highest possible water level of the water closet as installed.
4 Ball Test
Single Ball Test :The ball shall be made of non-absorbent material. The relative density of the ball shall be between 1.075 and 1.080. The diameter of the ball shall be 43 0.5 mm. Place the ball into the water closet to be tested and then flush the water closet. The ball shall be discharged in the normal manner.
The outlet (trap) of the water closet goes into the floor.
The outlet (trap) of the water closet goes into the wall.
5 Fifty Ball Test
Fifty balls of non-absorbent material, having a mass each of 3.7 ± 0.1 g, and a diameter of 20 ± 0.1 mm
shall be dropped into the water closet bowl and flushed. Repeat the test five times. A minimum of 85
percent of all balls should be flushed out in the five tests.
6 Load Bearing Test
force of 4 + ° .05 kN shall be applied for period of one hour by placing it on a wooden beam with a cross
section of 100 mm x 100 mm positioned across the centre of the opening of the top surface of the WC.
There shall be no damage or defect which shall occur to the WC.
7 Saw Dust Test
Specification of the Saw Dust 20 g of dry saw dust test sifted through 2 mm sieve.
Procedure: Set up the WC, cistern or flush valve and flush pipe (if required) as specified by the
manufacturer. Charge the WC with water to its designed water seal level. Fully wet the entire internal
surface of the WC below the rim. Sprinkle 20 g of fine dry saw dust of above specification on the inside of
the WC between the normal water level and the flushing rim as completely and evenly as possible. Then
flush the WC. The sprinkle saw dust should be cleaned below 40 mm of rim of WC.
8 Splash Test
Procedure: Set up the WC, cistern or flush valve and flush pipe (if required) as specified by the
manufacturer. Charge the WC with coloured water to its design water seal level. Ensure that the floor area
is cleaned and dry where the splash test to be carried out. Activate the flush valve or cistern to the
discharge the WC. Observe and record whether flushing water splashed over rim onto the floor. Repeat
the test 5 times. Record whether the flushing water splash over the rim onto the floor. Isolated droplets up
to 10 Nos., shall not be the cause for rejection.

Installation & Instructions

Wall hung
1. A cast-iron chair bracket grouted into the wall and the floor is recommended for use while installing SONA Wallvit Pan.
2. Cantilever brackets with provision of 4'' of the brackets into the wall can also be used.
3. The cantilever brackets used should have the distance between the center of the back and front slots as 95 mm.
4. Ensure that while grouting the cantilever brackets into the wall, they are fixed in exactly the same plane. A distance between centers of the slots of one bracket to the other brackets should be exactly as per diagram.
5. For either type of fixing, please ensure that a rubber gasket is fitted between the bracket and the closet to provide adequate cushioning and protection from direct contact between the ceramic closet and metal brackets.
Wall Mount Couple suite
Under Counter
NOTE :Do not use adhesives or adhesive sealants.
Apply a continuous bead of quality sealant to the basin rim where it will contact the counter top.
NOTE : The screws should be used on counter tops with a minimum
1" thickness for thinner counter tops, use appropriate anchors and fasteners.
1. For wood, wood composite and marble counter top install the basin to the counter top with the clamps and screws for other counter top materials, refer to the counter top manufacture's instructions for recommended instructions.
2. Position the basin squarely under the cutout before tightening the clamps. Draw the basin rim up to the counter top until it is sunk. Do not over tighten.
