SOURCE: Loss of pressure in kitchen faucet - Price Pfister

Your problem is a simple one.

  1. Turn off water to faucet.
  2. Place a towel(s) in the base of the sink(s) to prevent any parts from going down drain.
  3. Remove the handle to the faucet. (single handle only)
  4. If not a single handle then remove spout from faucet.
  5. If a single handle remove cap carefully and any loose parts.
  6. Gently turn spout side to side while lifting to remove.
  7. You will see a hole with a very small valve where the water comes out to the spout on the base of the faucet.

  1. Remove this valve (which is a backflow preventer) and replace.
  2. Reassemble and test.
Problem solved.

SOURCE: low pressure and flow on hot water side of single handle faucet

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.

SOURCE: FF-1800 HAS LOW HOT WATER PRESSURE AND DELAYED TIME TO GET HOT

Sometimes there is a lot of sediment released into the pipes (particularly hot water) when water lines are shut down and restarted as part of a remodel process.

Particularly with a pressure balanced faucet this can create all types of symptoms including those you describe...

Before you go to any expensive lengths, check any intake screens or strainers, both on the faucet and in the other components of the system. A lot of the time this will solve the problem...

SOURCE: No water pressure in kitchen sink. Not the aerator.

First of all we like to check the easy/cheap things first.

1. Are the shut-off valves closed lightly?

If they are closed, open them.....easiest fix of them all.

2. If the valves are open then possibly a washer is shifted.

Turn off the water supply at the valves under the sink. Remove the handles by removing the set screw under the handles. There should then be a packing nut which holds all of the "guts" of the faucet in. Remove this nut and pull out the long stem. On the bottom of this stem is a flat washer that may have been damaged or is just slightly shifted. EIther way, I would replace it if the faucet is more then a few years old as it is cheap and you already have access to it. WHen replacing the valve stem, be sure to use a plumbers grease on all rings and seals. The rest of the replacement is the same are the removal.



Hope this helps.

Debris can get into the shower body/cartridge. Pull out the cartridge and flush the shower body and clean out the cartridge. Sometimes you need to replace the cartridge.

Price Pfister hot water runs slow


Check the supply line and valve to see if any dirt or foreign.matter got into the line or valve when you changed out your faucet. if this is not the problem you may have a faulty faucet. You may be able to back flush the faucet with a garden hose by leaving the hot side open, but you will get wet. If you used Teflon tape on the supply line and it is a compression fitting, some of the tape could be blocking the water. for more info go to waterheaterflush.com

Heater takes more than 1 minute to get water to kit faucet , then temp fluctuates


1) Guesses: Sounds like a bad single-handled faucet cartridge, or low water flow at faucet, or clogged water filter.
Replace faucet cartridge, clean the aerator, and/or clean sediment out of pipes below sink, and clean water filter at tankless unit each month.

2) For exact measure of problem:
Typical faucet can have 2 gallon per minute flow rate.
2 gpm flow rate means faucet fills 1 gallon container in 30 seconds. Test faucet using 1 gallon container and a cooking timer to get flow rate.
Clean aerator to improve flow rate. Compare kitchen flow rate with other faucets in home.
http://waterheatertimer.org/Low-hot-water-pressure.html

Most homes have 1/2" diameter pipe running to kitchen faucet.
100 feet of 1/2" diameter pipe holds 1.2 gallons of water. This assumes no sediment build-up inside pipes.
http://waterheatertimer.org/Water-heater-recirculation-system.html

Assuming only hot is turned on: If faucet is 100 feet away from water heater, and pipe diameter is unobstructed 1/2" diameter, and faucet has 2 gallon per minute water flow, then hot water should arrive in 36 seconds.
50 feet away, and hot water should arrive in 18 seconds.

If kitchen has single handled faucet, and the handle is raised in the middle, then equal amounts of hot and cold water are drawn at same time. This doubles amount of time for hot water to arrive.

If single handle faucet has a bad cartridge, then faucet can have crossover.
Crossover means that cold water can enter the faucet even if faucet is turned to hot.
Bad single-handled faucet cartridge can delay or stop the arrival of hot water.
http://waterheatertimer.org/Crossover.html

Tankless require maintenance including cleaning combustion parts yearly, de-lime heat exchanger frequently, and clean water filter each month.

Low pressure on hot water setting.


You almost had the problem solved. After you back flush the faucet you need to disconnect the line just before the faucet and then run the water into a bucket or down the drain until the line is flushed out. Depending on the size and amount of debris in the line you may have to flush the line further back until you get all the junk out.
The white crystal like substance is scale, a build up of minerals from your water. It might be worth your while to check into a water softener. Most water softener companies will do free water testing to help you determine if you need one. Beware of the high pressure sales gimics though.

Hot water tap - no pressure and splutters


Do you have your own hot water tank? or is there one serving many units? There is a 'dip tube' in hot water tanks, if it gets old it sometimes deteriorates and small parts of plastic get loose and will float around in the tank, if a piece finds it way up to the outlet then that might explain why you are getting the low water pressure. one wat to check is to twist off the aerotor on the end of your faucet, if there are any small pieces of white plastic then you will have to replace the dip tube and maybe even flush out the tank. it is also possible that a piece of plastic has traveled up the water line and it stuck in the faucet cartridge.
