These are the 5 Best Water Softener for Crawl Space

What you should consider before buying Water Softener for Crawl Space

If your water source supplies you with hard water, you need a water softener. A water softener can provide you with pure and clean water. In the market, there are various types of water softeners. After reading the guideline below, you will understand which one is suitable for your house.

Types of water softener

There are six types of the water softener. (a) Salt-based, (b) Salt-free, (c) Dual tank, (d) Magnetic, (e) Portable, and (f) Reverse Osmosis water softener.

  1. Salt-based water softener cycles the household water through it. The working principle of this softener is ion exchange.
  2. Salt-free water softener used potassium-chloride salt instead of sodium. It is a good option if anyone wants to avoid the salt-based water softener. The softener doesn’t reduce the hard water minerals like salt-based. It prevents the minerals from being deposited.
  3. A dual tank water softener is best without any break-in service because when one tank is recharging, another one can supply the water.
  4. Magnetic water softener creates a magnetic field that changes the electromagnetic properties of the calcium-carbonate minerals.
  5. A portable water softener is usually a tiny version of a salt-based or salt-free water softener.
  6. Reverse Osmosis isn’t a water softener, but it can strip the water of all substances. Generally, it works for a single fixture.

Among them, portable and reverse Osmosis are for minor uses.

What size water softener do I need?

Generally, a person uses 75 gallons per day. Now multiple 75 with the number of a family member. Suppose the water hardness level is six gpg, then multiple 6 with the result.

Example: 75 x 6 x 3 ( number of family members) = 1350

With six gpg, a three-member family needs 1350 gallons of water daily.
