Why is the water flow slow in my Ispring CU-A4?
- A
  alvarezseanJul 28, 2025
  If you're experiencing slow water flow with your iSpring Water Filtration System, several factors could be the cause. First, check your water pressure by opening the kitchen faucet to ensure it's not lower than 20 psi. Second, review the installation date and replacement schedule to see if the filter cartridges are due for replacement. Finally, the first stage filter might be clogged by sediments; consider installing a whole-house sediment filter to protect your water appliances.

  If your Ispring Water Filtration System is leaking, ensure the tubing is pushed a full 1/2" into the fitting. If the leak persists, the O-ring on the fitting may not be creating a proper seal, and you should replace it.
