Installing a diaphragm Valve

• First you need to isolate the tank, when there is no valve turn off the main water supply.
• Now drain the toilet's tank by flushing the toilet.
• For water storage tanks, lower the water level by at least 6 inches first.
• Then disconnect the inlet pipe from the valve.
• Use 2 spanners to disconnect the float valve assembly from the tank.
• Now remove the float from the worn valve and connect it to the new one.
• The assembly should go through the hole in the side of the tank.
• Screw the nut onto the threaded shaft.
• Connect the float valve assembly using 2 spanners, and reconnect the inlet pipe.
• Turn the water supply  back on and watch closely for leaks as the cistern fills

Replacing a diaphragm valve

• First you need to isolate the tank, when there is no valve turn off the main water supply.
• Disconnect the retaining cap from the valve inside the tank at the end of the float arm.
• When the retaining nut is located at the front of the cistern then you should see the diaphragm behind the cap.
• When the retaining nut is at the back of the tank then you need to move the cartridge assembly to get to the diaphram
• Now before  you place the new diaphram make sure to clean all the parts in cold water first.
• Then reassemble the float valve and turn the the water back on.
