An easy caroma inlet valve repair.Welcome to my caroma inlet valve repair page. This valve is made with easy maintenance in mind so enjoy the steps and photos below. First you need to shut off the water supply. This will be next to the toilet tank. Test to see if water is shut off by pushing float down on inlet valve. If the shut off valve fails to shut down
Now take hold of the black nut and turn a 1/4 turn anticlockwise. Pull the nut away from valve body. This will reveal a rod and sealing washer.
Remove the sealing washer by prising it out with a fine screwdriver or fingernails. 
The black rod is connected to a rubber composite ball that pushes up against the sealing washer when the inlet valve shuts off. Most times you will find the reason the valve is not sealing is.... Dirt/grit on the ball or on the sealing washer. You need to clean both the ball and washer to enable a perfect seal. If the ball or washer looks perished, you will have to buy a replacement kit. You now need to insert the ball back into the valve body followed by the sealing washer. Replace black body nut. (Line up lugs and give a 1/4 turn clockwise to reassemble. Insert plastic circlip. Now turn the water back on and test. You can alter the water level by the nut adjustment on the side of inlet valve.
An optional filter clean is a good idea if flow rates have slowed down. Simply check the water is turned off to cistern. Undo nut that connect inlet valve to pipe. Pull pipe away from bottom of valve. Reach into the bottom of valve with long nose pliers and pull out filter.
Washer filter in bucket of fresh water and replace. Do nut back up and turn water back on. Congratulations, your caroma inlet valve repair is complete.
