Low flow remedies
1)
Clear the quick coupling
Look under the sink and locate the yellow & black quick coupling. Pull down
on the yellow ring and the quick coupling will detach from the mixed water
supply tube.
Tap or rinse out the debris from the top of the coupling. The quick coupling can be
easily unscrewed from the hose if needed.
When the coupling is clean, screw it back on the hose. Hand tighten only.
To re-attach, slide the yellow ring back and press the coupling onto the tube. Test
the connection by pulling lightly down on the hose.
If the flow is not restored, go to step 2.
2)
Clean the spray head restrictor
Unscrew the spray-head from the hose and look into the connection end of
the spray-head.
Flow-restrictor
Inside of the connection piece, there is a flow-restrictor that can get filled with fine
sand or dirt. Rinse out the dirt. If the black rubber o-ring is removed for cleaning, it
must be replaced to meet federal flow requirements.
If the flow is not restored, go to step 3.
3)
Clean the aerator
Unscrew the aerator housing (X) using a crescent wrench on the “flats” provided.
The aerator (Y) will drop out, and use a toothbrush to clear debris from the inlet
screen or soak it in a descaling solution (e.g. 50/50-mixture of white vinegar and
water).
The aerator cannot be taken apart.
