How to Choose the Best Water Softener Resin
Choosing the best resin for your household can be tricky. But it doesn’t have to be if you know what to look for! Here’s a list of the factors to consider before buying your resins:
The two most popular types are ion exchange resins and fine mesh.
Ion exchange or cation resin is better at filtering out small particles than fine mesh. Consider it when removing hard water minerals between 3-5 ppm. Ion exchange resin is the most popular for standard home water softeners.
Fine Mesh Resin
Fine mesh resin is more effective at filtering out larger particles than ion exchange resin. It’s often used where the water supply contains a lot of iron. Usually, it removes water hardness up to 10 ppm.
A common concern with fine mesh resin is that it reduces water pressure due to smaller beads. Also, the beads might slip through into your water supply unless you install a specialized bottom basket.
Resin bead crosslink percentage is how much resin beads are bonded together. It can be an indicator of the hardness and durability of the resin bead.
Crosslink percentage range from 4-10%. However, the two most popular are 8% crosslink and 10% crosslink.
The 10% crosslink resin is more durable and often found in high-end salt-based water softeners. It comes in handy in situations where additional chlorine resistance is necessary. A 10% crosslink resin can easily last 20-25 years. One drawback, however, is that it causes pressure drops due to smaller bead sizes.
The 8% crosslink ion exchange resin is the most popular. It tends to hold more water due to large resin beads. With a 10-15 years lifespan, it’s quite durable but not as durable as the 10% crosslink resin.
This crosslink resin is ideal for tough to medium water, such as well water. Also, it removes hardness minerals between 3-5 ppm.
Find out how much resin is required for your particular water softener model before ordering any replacement resin. How much you need depends on the size of your resin tank.
Usually, the resin tank has a sticker containing four digits. The first two digits indicate the tank’s diameter in inches. On the other hand, the last two digits indicate the tank’s height in inches.
For example, let’s say the sticker reads 1054. This means the tank has a 10-inch diameter and a 54-inch height.
However, if you find no sticker, you can still measure the tank’s height and diameter.
This chart shows how much resin you need for different resin tank sizes.
|Tank Diameter (Inches)
|Tank Height (Inches)
|Resin Capacity (Cubic Feet)
So, what are the best materials for resin replacement media?
For best results and long-life performance, choose DVB and polystyrene resin beads. Most often, they’re referred to as polystyrene or gel resin.
Ease of Use
Filling up the resin tank can be quite troublesome. But it’s less likely you’re willing to spend more on professional help. Hence, choose resin beads that are easy to install.
For this reason, you might want to consider resin beads with built-in spouts. Or better still, those that come with a filling funnel.
