A blending valve is on the side opposite of the bypass handle. It allows you to adjust the hardness of the water exiting your unit. Some people dislike the feeling of soft water so a blending valve can add in a small stream of hard water to the softened water as it exits the unit. Used on units: RHS42 / RHW42
To Use:
- To use the blending valve, you’ll have to unlock it by turning the hex nut counterclockwise (pictured above).
- Once unlocked, you can adjust the hardness of the product water by turning the blending valve counterclockwise. The valve will rotate 6 times max – be careful not to rotate too far or the valve may unscrew from the bypass and cause a leak.
- The further you unscrew the blending the valve, the more hardness will be added to the product water exiting the softener. If you twist it clockwise, you are closing the valve to leave out hard water.
- Once the desired position is achieved, hold the bypass handle with one hand and tighten the hex nut clockwise snug against the end cap with a wrench. This will lock the position of the blending valve.
If you twist the valve counter clockwise as much as it can (up to 6 times,) it will be considered OPEN - meaning you are letting hard water in.
When you twist it clockwise as far it can go, it's considered CLOSED - meaning you aren't letting hard water in.
