Why Pfister Faucet No Hot Water?

If you know the cause of the Pfister faucet no hot water issue, it becomes easy to find its solutions. Here are 5 common reasons why your Pfister faucet not dispensing hot water.

Why Pfister Faucet No Hot Water?

1. Airlock In Pipes

What’s causing your Pfister faucet to only dispense cold water? The Culprit could be trapped air.

Has your hot water heater been humming along without issue, yet your Pfister faucet refuses to dispense anything warmer than cold water? Trapped air the pipes block the way of the water.

Airlock generally happens in the hot water supply line of the faucet. Because hot water flows from your water heater, not directly from the main water supply like the cold tap does. Due to this, the pressure of hot water is lower than cold water.

Robust cold water pressure can push through and force out any trapped air bubbles, the hot line’s weaker pressure often can’t. So, these air bubbles in the hot water pipes stuck and obstruct the path of hot water.

Solution:

To fix the airlock situation in hot water pipes, you need to use a cold water supply. Attach a hosepipe with one end at the mouth of the hot water tap and the other at the end of the cold water tap without leaving any space.

Turn on the Pfister hot water faucet and then turn on the cold water faucet. The high pressure of cold water will be enough to release any air trapped in the Pfister hot water line.

Keep running the cold water for 30 seconds to 1 minute. If you see an improvement in the hot water supply, you can repeat this process a few more times to get a proper flow of hot water from the Pfister faucet.

2. Issue With The Water Heater

The issue with Price Pfister hot water faucet might be caused by the water heater. These appliances endure a lot of wear and tear from constantly heating water, so problems are inevitable over time.

Inside the water heater, there’s a tank where the hot water is stored. This tank has a pipe that carries the hot water to your faucets. But if this pipe gets clogged or blocked, the hot water can’t flow out as fast as it should.

Sometimes, minerals and small particles in the water can build up in the pipe over time. This build-up can slow down the flow of hot water. So, even though your water heater might be making plenty of hot water, it can’t reach your faucets with good pressure because of the blockage in the pipe.

Solution:

To fix this issue, you might need to clean out the pipe or the water heater. For this, you need to remove built-up gunk so that the hot water can flow freely again.

  • For safety, you should turn off the power to the water heater. Also, turn off the water supply of the water heater.
  • Connect a garden hose to the drain valve located near the bottom of the water heater.
  • Now open the drain valve and let the water inside the tank drain out. This will help flush out any sediment or debris that has settled at the bottom of the tank.
  • Once the tank is empty, turn on the water supply for a few minutes. This will help flush out any remaining sediment. You’ll see the water coming out of the hose might be cloudy or dirty at first.

If you notice mineral buildup inside the tank or on the heating element, you should descale the water heater. You can do this by mixing a solution of vinegar and water (or using a commercial descaling product) and letting it sit inside the tank for a few hours. Afterward, drain the tank again and flush it out with clean water.

Some water heaters have a sacrificial anode rod that helps prevent corrosion inside the tank. If your heater has one, you can check its condition. If it’s heavily corroded, you might need to replace it.

If you’re not comfortable doing this yourself, it’s a good idea to get help from a plumber or someone who knows about water heaters. They can check and fix the problem for you.

3. Cartridge Causing Issue

Not only in hot water supply, but cartridges also cause other issues. The mainly single-handle faucets face faulty cartridge issues.

The debris or buildup or dirt will accumulate on the cartridge and block the way of the hot water. So, you don’t get hot water from the Pfister faucet.

Solution:

Tools you need to remove and clean the cartridge:

  • Adjustable wrench
  • Screwdriver (if necessary)
  • An old toothbrush or cleaning brush
  • White vinegar or a mild cleaning solution
  • Towel or rag
  • Make sure you have all the necessary tools and cleaning supplies ready before you begin.
  • Locate the water shut-off valves under the sink and turn off the water supply to the faucet. This will prevent any water from flowing while you’re working.
  • To access the cartridge, you need to remove the Pfister faucet handle.
  • Look for a screw or cap at the base of the handle and use a screwdriver to remove it. Once the screw or cap is removed, gently pull the handle off.
  • Use an adjustable wrench to loosen and remove the retaining nut that holds the cartridge in place.
  • Fill a bowl or container with white vinegar or a mild cleaning solution. Place the cartridge in the solution and let it soak for about 15-30 minutes.
  • After soaking, use an old toothbrush or a cleaning brush to gently scrub the cartridge.
  • Rinse the cartridge thoroughly with clean water to remove any residue from the cleaning solution. Once it’s clean, carefully insert the cartridge back into its housing. Slide the retaining nut back on and tighten it by turning it clockwise.

4. Blocked Pipes

You turn on the Pfister faucet but no hot water comes out from it. Blocked pipes are another cause for this issue.

When your Pfister hot water tap does not give any water, check if all the taps in your home have this issue. Look at the kitchen sink, shower, and other places you get hot water.

If the other taps have hot water but one does not, there is likely a blockage in that tap’s hot water pipe. The mineral build-up, gunk, and sediment usually cause a tap to get blocked. The pressure of the hot water also makes this worse.

This problem, along with low water pressure, stops water from fully flowing to the tap.

Solution:

Turn the control valve to the highest setting. This ensures you are not limiting the already low pressure. Check two spots to see if there is a blockage: the aerator and the tap itself.

If the pressure cannot push out the blockage, remove the screw on the aerator. See if dirt has built up there. Clearing the dirt and putting the aerator back on the tap is an easy fix.

The tap itself may also be blocked. In that case, turn off the water supply lines. Remove the tap to clear it out. Vinegar, water, and a long brush help clear tap blockages.

Letting vinegar sit in the tap overnight also helps. It softens the dirt and makes it easier to remove.

5. Faulty Water Valve

All water in your home goes through valves before reaching the taps. A faulty valve can stop the water flow. Check the valve for your hot water tap that runs through the water heater.

Another issue may be with the tap washer. If the tap is bad, it will limit hot water flow. You can check if the tap flows more freely than normal.

If it does flow more freely, the tap is compromised. In this case, replace the tap with a new one for the best solution.

Solution:

If the valve is locked shut, open it to restore flow. But if the hot water valve is damaged, you need to buy and install a new one on the sink.

What Controls Water Temperature In Faucets?

What Controls Water Temperature In Faucets?
  • Hot and Cold Water Supply Lines – The hot and cold water lines running to the faucet determine the range of temperatures available. The hot water line brings hot water from your water heater while the cold line brings unheated water from the main water supply.
  • Faucet Cartridge/Valves – Inside the faucet are cartridges or valves that control the mix of hot and cold water. Single-handle faucets use cartridges with a movable stopper that adjusts the flow of hot and cold water to set the temperature. Two-handle faucets have separate hot and cold valves that are adjusted to control the mix.
  • Thermostatic Valve – Some faucets have a thermostatic valve that allows you to preset your desired water temperature. When the water reaches that set temperature, the valve automatically adjusts the hot/cold mix to maintain it.
  • Anti-Scald Valves – Many faucets also come with anti-scald valves as a safety feature. These valves limit the maximum hot water temperature coming out of the faucet to prevent accidental scalding.

Final Thoughts

The above solutions are not tough and can be performed by yourself. When you try these solutions, you will get back the hot water supply in the Pfister faucet. Know the cause of the Pfister faucet no hot water pressure issue and start applying the appropriate solution for it.
