Frequently Asked Questions

What kind of salt should I use in my Pentair softener?

Pentair recommends 99% salt crystals. You can find this salt at your local grocery store, hardware store or gas station.

What is the warranty policy on my water softening tank?

You can find Pentair warranty policies by clicking the button below.

How can I find the manufactured date on my water softening tank?

The manufacturing date and serial numbers are on your tank’s label. They are located below the model number. 


Why does my water softener fail to regenerate?

The following is a list of common reasons as to why this may be happening:

  • The unit is unplugged or no power is going to the unit.
  • The unit is in bypass.
  • The meter is counting gallons remaining off of the timer.

Why doesn’t my water feel slippery when washing dishes anymore?

Your water may not feel slippery because your water softener may not be re-generating. Another reason may be that there is no salt in your brine tank.

Is my water softener using too much salt?

You can tell if your water softener is using too much salt by verifying that your capacity, hardness, meter setting and salt dosage are set correctly for the size of your system. Next, check if your brine tank is full of water.

  • If it is, push the float down and see if the brine tank starts to fill.
  • If it is not, check if your brine valve refill amount is correct.  

Why is the water pressure in my home low?

To determine the potential cause, put your water softener in bypass and see if the pressure increases.

  • If the pressure does not increase, then the restriction is in your plumbing. Check all shut off valves.
  • If the pressure increases, the pressure drop is within the water softener system. You may need to replace your resin.
  • If the issue persists, contact your installer, dealer or Pentair technical support for further assistance.

Why are my drains plugged with resin?

Check that the inlet and outlet plumbing on your softener is not reversed. If your inlet and outlet are plumbed correctly, your distributor assembly is likely cracked and needs to be replaced. Contact your installer or dealer for further assistance.

Why do I still have reddish staining on my fixtures if I have a water softener?

Check your programming to confirm that the correct iron amount is set for your hardness level. If that is correct, check the following:

  • Does the unit regenerate? If not, please reference FAQ 4.
  • Do you have low pressure? If yes, please reference FAQ 7.
  • Have you tried using resin cleaner? If yes, you may need to rebed your system.

How and when do I replace my Pentair Whole House Filter?

You should replace your Pentair Whole House Filter when there is a noticeable change in appearance or taste in the water, or when substantial reduction in flow occurs. Timing can vary depending on your water source, but filter cartridges should be replaced at least once a year. See video for detailed instructions.

How do I replace the filter underneath my sink?

The replacement process is simple to do on your own, but a local water treatment professional or plumber can help if needed. 

  • Turn off cold water supply and open the drinking water faucet to release pressure from system.
  • Unscrew and remove bottom of filter housing. Locate and remove O-ring, wipe clean of lubricant, and set aside.
  • Discard used filter cartridges. Using a non-abrasive sponge or cloth, scrub the bottom of filter housings, O-ring grooves, and caps with dish soap and warm water. Rinse thoroughly. Fill bottom of each housing one third full with water. Add two tablespoons of household bleach and scrub to disinfect.
  • Lubricate O-rings with silicone grease. Insert O-ring in groove and press into place.
    NOTE: This step is important to ensure a proper housing seal. Make certain each O-ring is seated level in its groove or a leak may occur.
  • Insert filter cartridge in bottom of filter housing.
  • Screw bottom of housing onto cap and hand tighten. DO NOT OVERTIGHTEN. Using the wrench could result in over tightening and may compress the O-ring too much, causing a leak.
  • Flush filter for 10 minutes before use.

Does a water softener alternative address issues like dry/itchy skin, brittle hair, and lathering like traditional water softeners do?

In short, no. If you are experiencing issues like dry or itchy skin or brittle hair you sholud opt for a traditional, or salt-based water softeners.

Should I choose a water softener or water softener alternatives?

It really depends on your lifestyle, budget, and unique home water challenges. For example, traditional water softeners use salt to reduce hard water-causing mineral ions, like calcium and magnesium. Water softeners can reduce any level of hard water, including moderate and very hard water, resulting in softer skin, shinier hair, longer lasting and more efficient appliances, and less hard water scale buildup. Salt does need to be replenished on occassion.

Water Softener Alternatives, on the other hand, do not require salt refills, making these systems more hassle-free. They also do not require electricity to operate.

You can learn more about hard water or dive deeper into the differences of traditional water softeners vs. water softener alternatives here.

Will installing a softening system restrict the water flow or pressure in the house?

Yes, the water has to flow through the unit and the resin. These cavities will create a pressure drop. Based on the size of the system and at what flow rate will determine how much pressure drop there will be.
