Have you noticed you're getting low water pressure with your faucet? You may have a clog or block somewhere in your system. Going through the steps below will help determine the source of the issue. Never worked on your system before? Don’t worry! We'll go through this together. If you have a Reverse Osmosis system, please click here to troubleshoot, otherwise, continue on.
Before You Start
- You'll want to check your incoming water pressure to make sure it's at least at 30 psi. Anything below that will slow down the system. Click here for instructions on how to check your pressure.
- Confirm the filters on your unit have been changed in the last 6 months. If it's been longer than 6 months, you'll want to replace them.
Troubleshooting Steps
The following steps apply to the WHED20, WHADUS5, WHEMB40, and WHAMBS5. The photo below demonstrates a WHEMB40.
1. Go ahead and remove Filter 1 on your unit (each filter is labeled with a sticker). To do this, grab hold of the filter and twist it counter-clockwise until it disconnects from the Manifold/Head Assembly. (You'll leave the second and third filters on the system.)
2. On the Manifold/Head Assembly (where the filter was connected, pictured below), you'll see a white plastic poppet valve. The poppet looks like a 3-sided stem sticking out of the hole.
3. With your face out of the way, push the poppet in – you’re looking to see if water is spraying through these. Did you get a good spray of water from the poppet?
NO - Click here if there's NO water coming from the poppet.
If you don’t have water flow you’ll want to test the supply hose.
1. Now, you’ll turn the water off to your system and remove the yellow hose from the Manifold/Head Assembly. To remove the line, push IN on the yellow port, and pull OUT on the hose.
2. Place the open end of the yellow hose in a bowl and slowly turn the water back on. You're confirming there's good pressure coming through that line.
3. Turn off the water supply and reconnect the yellow hose, making sure it's secure.
4. With your face out of the way, push the poppet in once more. If there's still no water flow, it's likely the Manifold/Head Assembly is blocked and we recommend you replace it. You can find information on how to purchase replacement parts here or check out our article What is My Warranty to see if you're still covered.
5. Make sure to reattach your filter by turning it clockwise and twisting it into place.
6. Lastly, you can turn your water supply back on. Nice work! You've completed the troubleshooting steps for your low water flow issue. If you still need assistance, please Contact Us.

YES - Click here if there IS water coming from the poppet.
We'll need to check the other poppets on the system.
1. Now reattach that first filter by lining it up and turning it clockwise until it's fully connected to the Manifold/Head Assembly.
2. Go to the next filter and remove it off the system by turning it counter-clockwise, like mentioned above. (The first and third filters will be the ones on your system at this time.)
3. Again, with your face out of the way, push the poppet in – you’re looking for a good spray of water here.
4. Reattach the second filter by lining it up with the Manifold/Head Assembly and twist it clockwise until it's fully connected.
5. Now, let's check the last spot. Remove the third filter from the Manifold/Head Assembly. (The first and second filters will still be on it).
6. With your face out of the way, push the poppet in – you’re looking for a good spray of water here. Are you getting a weak spray from the poppets?
- YES - If you're getting a weak spray from your poppets, your filters need to be replaced. You can find information on how to purchase replacement parts here.
- NO - We'll need to check the blue hose to make sure there's not a blockage in the hose or faucet. Continue onto step 7.
7. Go ahead and reattach that last filter.
8. You'll need to turn off the water to your system.
9. Now, detach the blue hose by pushing in on the collet port and pulling out on the hose. Open the filtered water faucet and now blow through the blue hose, confirming air can pass easily. If not, there's a blockage in the hose or faucet.
10. Next, place the blue hose into a bowl. Turn the water on to see if you're getting water flow through the filters. Then turn the water supply back off.
11. Reattach the blue hose onto the Manifold/Head Assembly. If you are still experiencing low water pressure, your filters need to be replaced. You can find information on how to purchase replacement parts here.
12. Don't forget to turn your water supply back on. Nice work! You've completed the troubleshooting steps for your low water flow. If you still need assistance, Contact Us.
