DISASSEMBLY
If the whole valve needs to be removed from the water
supply for servicing, please be aware of the cautions
below:
1. Be careful not to lose or tear the friction washer at the
outlet connection to the vacuum breaker tube nut. To
maintain a proper seal, replace the washer if necessary.
2. When re-installing the valve to the water supply, avoid
pinching the o-ring.
CLEANING PISTON ASSEMBLY AND FILTER
1. Turn the screw of the control stop clockwise to turn off
the water.
2. Take out the piston assembly (except for TEU1UA(R)(X))
or take out the filter for TEU1UA(R)(X).
3. Check the small hole in the piston to see if it is clogged
with debris. Insert a small wire to unclog hole if needed.
4. Check the filter to see if it is clogged with debris and
gently brush it clean.
5. Check the sealing area of the piston and clean it if it is
dirty.
6. Check the U-packing for cracks or damage.
