What to do if my AquaSure AS-PR75A Water System dispensing faucet has low water pressure?
- K
  Kevin HarrisAug 23, 2025
  Low water pressure from the dispensing faucet of your AquaSure Water System can arise from several causes: 1. Incorrect air pressure in the holding tank: Empty the tank, shut off the feed water, remove the tank, add air to the valve stem until all water is removed, pressurize to 8 psi, reinstall the tank, and turn on the feed water. 2. A clogged carbon post filter: Replace the post filter. 3. A partially closed holding tank valve: Fully open the tank ball valve. 4. A faulty faucet: Repair or replace the faucet. 5. Heavy water use: Allow the holding tank to refill for about an hour. 6. Low water production: See “Not enough water from holding tank” for troubleshooting.

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.

- 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 my AquaSure Water System slow to shut off?
- C
  Chelsea CannonSep 2, 2025
  An AquaSure Water System that is slow to shut off can be attributed to: * Insufficient water pressure: Ensure incoming water pressure is above 40 psi. Install a booster pump or permeate pump. * Feed water valve not fully open: Open the feed water valve fully to lessen the restricted flow. * Clogged sediment/carbon pre-filters: Replace the filter.

Why does my AquaSure AS-PR75A Water System not shut off?
- Q
  qcookSep 5, 2025
  Your AquaSure Water System might not shut off because: * The automatic shut-off valve is defective: Test the functionality of the automatic shut-off valve by closing the tank ball valve to see if the system will shut off. If it continues producing water, replace the valve. * The automatic shut-off valve is not defective, but incoming water pressure is too low: Ensure incoming water pressure is above 40 psi. Install a booster pump or permeate pump. * The system is feeding multiple outlets: This is normal as the system constantly produces water to supply the outlets.

Why is the water pressure low from my AquaSure Water System faucet?
- A
  aguzmanSep 6, 2025
  Low water pressure from the AquaSure Water System dispensing faucet is often due to incorrect air pressure in the holding tank. To fix this, empty the water from the holding tank, shut off the feed water, and remove the holding tank. Add air to the air valve stem. If water remains in the tank, continue adding air until it's all removed, then pressurize to 8 psi. Re-install the tank, turn on the feed water, and allow the tank to refill. Other causes could be a clogged carbon post filter (replace it), a partially closed holding tank valve (open it fully), a faulty faucet (repair or replace it), or heavy water use (allow the tank to refill).

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.
