Eight steps to determine the problem...
1. Gather Information
Ask the customer questions. Any information obtained can reduce your
time on the job. Many times, the customer’s response to questions will
allow you to skip directly to the next section.
2. Test the water
Test hot, cold and raw.
• Hot water, stored in the water heater, can tell you what the water was
like yesterday.
• Cold water, directly from the filter, tells you what the water is like
right now.
• Raw water, before treatment, tells you if the water to be treated has
changed and if the correct meter disc was installed originally.
Is there really a problem with the filter? Or does the problem lie elsewhere
at the customer site?
3. Observe the Installation
Look for customer-related problems.
• Is the by-pass open or leaking?
Look for obvious installation mistakes.
• Is the meter disc correct according to raw water?
• Is the by-pass disc correct?
• Are the inlet and outlet lines reversed?
• Drain installation – Are there any kinks, restrictions or T's from other
appliances using water?
Is the unit running water to drain?
Refer to the section for problems and solutions.
4. Run the filtered water faucet
Watch the meter disc.
• Is it turning?
Watch the no back pawl.
• As the meter disc turns clockwise, the no back pawl should drop into
the next tooth, preventing the meter disc from turning backwards.
Does it?
Measure the metering rate.
• Wait for the no back pawl to drop into a tooth. Let the meter disc
turn for another tooth or two. The approximate metering rate is
shown below.
