Why is there no water coming from my AquaSure AS-PR75A Water System faucet?
- J
  Jessica MullinsSep 14, 2025
  If there's little to no water at your AquaSure Water System dispensing faucet, first check if the water is shut off at the stop valve (open it). Also, ensure the Flowlok is in the open position (lever should be lowered). Other potential issues include a crimped output line (reroute it), a tank that isn't pre-charged (empty and recharge it), a defective tank (replace it), a tank that hasn't filled yet (allow it to refill), insufficient water pressure (install a booster pump or permeate pump), or incorrect installation (check the installation guide).

Why does my AquaSure AS-PR75A Water System tank take a long time to fill?
- B
  Bradley ChangAug 27, 2025
  The AquaSure Water System tank might take a long time to fill due to: * Insufficient water pressure: Ensure incoming water pressure is above 40 psi. Install a booster pump or permeate pump. * Lower water temperature: Cold water affects system performance. Install a booster pump or permeate pump to compensate.

How to fix drain water overflows at the air gap faucet in my AquaSure AS-PR75A?
- A
  andrewbutlerAug 27, 2025
  Overflowing drain water at the air gap faucet in your AquaSure Water System can be caused by: * A clogged air gap: Clear the air gap. * A clogged drain line: Clear the tubing. * A drain flow rate that is too high: Replace the flow restrictor.

Why does my AquaSure AS-PR75A have taste and odors in product water?
- C
  Carlos GoodmanAug 29, 2025
  Taste and odors in the product water of your AquaSure Water System can be caused by: * An exhausted carbon post filter: Replace the filters. * Foreign matter in the holding tank: Clean, flush, and sanitize the holding tank. Replace filters. * Reversed product water and drain water lines: Correct the plumbing. * Dissolved gases in feed water: Pre-treat feed water to remove gases. * Increase in product water TDS: See “Product water is high in total dissolved solids” for troubleshoot.

What causes my AquaSure AS-PR75A Water System to make a humming noise?
- R
  Randy CabreraAug 30, 2025
  The humming noise in your AquaSure Water System is caused by: * An air bubble trapped inside the housing: Purge the air by tilting the system on one side, shut off the tank ball valve, and turn on the dispensing faucet for about 1 minute. Repeat 3 or 4 times to purge out all the air.

Why does my AquaSure Water System faucet leak or drip?
- M
  Marie ColeSep 1, 2025
  Leaks or drips in your AquaSure Water System faucet can occur due to: * Water leaks from faucet spouts: Adjust the faucet by turning the tee bar located under the handle to provide a small amount of free play in the handle when shut off. If this doesn't work, repair or replace the faucet. * Water leaks from beneath the handle: Repair or replace the faucet.

Why is there not enough water from the holding tank in my AquaSure AS-PR75A?
- E
  Earl HerreraNov 21, 2025
  Several factors can cause insufficient water in your AquaSure Water System's holding tank: * A plugged feed water valve: Open or unclog the valve. * Clogged sediment/carbon pre-filters or carbon post filter: Replace the filters. * Low incoming water pressure: Ensure pressure is above the recommended PSI level, and install a booster or permeate pump if needed. * A fouled reverse osmosis membrane: Verify incoming water pressure is within limits, ensure the drain line isn't clogged, and replace the membrane. * Incorrect air pressure in the holding tank: Empty the tank and ensure the air pressure in the valve stem is between 5-10 psi. * A ruptured air bladder: Replace the holding tank. * A closed holding tank valve: Open the valve. * A clogged drain flow restrictor: Replace th...

What to do if my AquaSure Water System product water has high in total dissolved solids (TDS)?
- R
  robertsonmichaelNov 24, 2025
  High total dissolved solids (TDS) in your AquaSure Water System's product water may be due to: * Clogged pre-filters: Replace the filter. * Low incoming water pressure: Ensure incoming water pressure is above 40 psi. Install a booster pump or permeate pump. * Expanded reverse osmosis membrane: Check the TDS level of incoming water. If it exceeds the recommended range, pretreatment may be needed. Replace the RO membrane. * Reversed product water and drain water lines: Check the connection and correct the plumbing. * Clogged drain flow restrictor: Replace the drain flow restrictor. * Clogged air gap faucet: Clear or replace the air gap faucet. * Automatic shut-off not closing: Repair or replace the automatic shut-off valve. * New carbon post-filter not rinsed completely: Dra...

Why does my AquaSure AS-PR75A tank take so long to fill?
- R
  Richard EdwardsSep 12, 2025
  If your AquaSure Water System's tank is taking a long time to fill, it could be due to insufficient water pressure. Ensure incoming water pressure is above 40 psi. If it's not, install a booster pump or permeate pump. Additionally, lower water temperature can affect the system's performance; consider installing a booster pump or permeate pump to compensate.

Why does my AquaSure Water System have high TDS?
- J
  Joseph ArmstrongSep 9, 2025
  High total dissolved solids (TDS) in your AquaSure Water System's product water can be caused by several factors. Clogged pre-filters (replace them) or low incoming water pressure (install a booster pump or permeate pump) could be the issue. The reverse osmosis membrane might be expanded (replace the RO membrane), or the product and drain water lines could be reversed (check and correct the plumbing). Other potential causes include a clogged drain flow restrictor (replace it), a clogged air gap faucet (clear or replace it), a malfunctioning automatic shut-off (repair or replace it), a new carbon post-filter that hasn't been rinsed completely (drain the holding tank twice), or an increase in the incoming feed water TDS.
