Troubleshoot
The following guidelines are intended for troubleshooting simple and common issues. If you nd that you cannot
x the problem yourself please consult a local plumbing professional, or contact our customer service hotline at
1-800-928-7624. Please do not attempt to disassemble and repair the Purlette system, as such action could result in
damage to the system and void of warranty.
Issue Possible Cause
Recommended Action
The level of TDS in feed water exceeds
the maximum level permitted by the EPA
for public drinking water
Water yield decreases drastically
The water valves are not fully open,
resulting in a reduction in water ow
Expired lter life or clogged lter
Check to ensure that the three-way water ball valve
and the cold water supply valve are fully open.
Replace the damaged/expired lters.
Filtered water quality is poor
(High TDS level)
Filter not in use for an extended period
of time (over 3 days)
Possible expired lter or clogged RO
lter
Turn on the drinking water faucet and let it ush for
3-5 minutes.
Replace the expired/clogged lter.
Immediately uninstall the Purlette system to avoid
system damage.
Install a pretreatment device to the cold water supply
stop valve or main water shutoff valve.
Measure the source water TDS level with a TDS
meter to ensure that the feed water TDS is now
below 500ppm.
Reinstall the Purlette system after the pretreatment
device.
TDS is high, but lters have been recently
replaced
*If water source has a TDS of over 500 ppm, a pretreatment device is required to be installed before using the system.
