    Normally the light on the faucet flashes blue when working & red when the batteries need changing. We've changed the batteries & the light is still flashing red 3 times w/a 3 second delay between the flashes.

    The red light flashes 3 times & then has a 3 second delay before flashing again 3 times, etc. Area on top is dry w/no pooling water.

It could be one of two problems, one simple, one serious.

  • Easy fix
  1. Turn off hot water angle stop under sink to faucet.
  2. Remove supply line from hot angle stop.
  3. Place end of supply line in a small bucket to catch some water.
  4. Turn on cold water for a couple of seconds and backflush debris from faucet.
  5. Reconnect supply line.
  6. Turn on angle stop and test
  • Complex fix
If you have steel pipes you may be experiencing reduced flow due to corrosion in your pipes. Reduced hot water pressure in the kitchen faucet is usually the first sign since this is the faucet that is most used in the home.

Repiping is a job for a professional. Another symptom you may need a repipe is orange colored or rusty water.

    I had this same problem, and solution 1 worked great. Thank you!

    Your welcome! Since I wrote that solution another problem has surfaced that could be solution #3. Chloromine in the water supply swells the rubber washer in the angle stop requiring replacement of the angle stop. You should consider hiring a pro to do this too if your skill level in plumbing is not advanced.

First answer is pretty much the same as mine, but here are some details FWIW -- I had a similar problem ending with pretty much the above solution after some exploring. First, I checked the faucet valve itself. Opened it up and it was fine. Then I checked the shutoff valve. It was also clear. Then I checked the hose from the shutoff valve to the faucet. No kinks, but there was a little piece of plastic slightly sticking out on the shutoff valve end. I pulled that out with pliers and reattached the hose. The water ran fine for a second, then slowed down again. There was clearly something in there, so I disconnected the hose from the shutoff valve and let it hang with a clear glass bowl under it. Then I turned on the hot water faucet, put my hand over the spout, and turned on the cold water faucet, forcing cold water backward through the hot water side. (With a one handle faucet, you would turn it on in the middle position to get this back flushing.) More pieces of plastic came out of the hose into the glass bowl. The pieces looked like broken bits from an old valve. These faucets were replaced just before we moved in 3 years ago, so this stuff might have been from the old faucet. A few months ago, my water heater was replaced, so it could have been junk from that. Bottom line: after that backflush, all is well.

I have a Delta kitchen faucet model #467-SSSD-DST. The cold water flow and/or pressure is not adequate. The flow and pressure from the hot water side is fine. What may I do to fix my cold water problem?


Hi,
Take the handle off (set screw underneath)
Then turn the top off under the handle....make sure water is off...
then you will find a ball with the handle stem on it....note the position of it and pull it out...
under there are two wets of springs and rubber seats...
pull the right side out and check the hole for a blockage...(dirt or rust)
if none is visible, you may have to unhook the cold water supply hose
and then blow compressed air back through the hole to remove the blockage...
then reassemble...

We have a Delta 172 single handle faucet. We had our hot water heater replaced. Now it takes longer for hot water to get to the faucet. Could debris (calcium build up, etc.) from the replacement get in...


Yes, debris from water heater replacements often breaks lose and gets stuck. The problem could potentially be anywhere between water heater and the faucet. The faucets shut off valves or the Delta faucet cartridge itself. Turn the hot and cold water valves off under the sink and disconnect the water supply lines from the faucet. aim the water supply lines into a bucket and turn the valves on one at a time. If there is a significant reduction in the water pressure and volume on the hot water side, you need to replace the shut off valve. If there is no reduction in water pressure, you need to clean and/or replace the Delta faucet cartridge. Contact Delta to receive free replacement parts.

Pressure surging thru Delta single handle faucet. The water flow starts and stops suddenly when the faucet is more than half way on. Same for hot and cold.


I don't know if this is your problem or not, But I had a new faucet and it did the same thing. I found little tiny pieces of polishing media stuck in side the faucet. Every time you turn on the water it comes out fast , then trickles, drove me nuts, I took it back and got another, no problem, hope this helps.

Very low pressure on delta 470 faucet


To get full pressure you need to pull the wand away from the base. Then remove the wand from the hose becareful not to loose the washer. When the wand is removed look down the wand you will see a plastic part. That plastic part is a flow restrict-er. You need to put a screw in the restrict-er and pull it out. When it is out put wand back on the hose then you will have full water pressure.

The pressure in my Delta faucet is suddenly low. The pressure throughout the rest of the house is fine. What is wrong? I replaced several pieces of the faucet but nothing worked.


Take the hoses off on the bottom of the faucet and blow air back through the faucet. Dirt can plug up the small openings right where the water enters the faucet. By the way I hope you checked the areator on the end of the spout, Dirt can plug that up also.

Faucet/sprayer coordination


If you have a Delta faucet your diverter may need to be replaced. The diveter is located under the spout (see diagram)(this is not your faucet but works the same)

Here are the instructions:

  1. Turn off water to faucet.
  2. Remove handle.
  3. Remove top cap.
  4. Turning spout back and forth gently lift and remove.
  5. Remove and replace diverter.
Hope this helps and please remember to rate this!
