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. If you desire slightly harder water, the blending valve can add a small stream of hard water to the softened water as it exits the unit. Used on units: RHS42 / RHW42
- To open the blending valve, you’ll have to unlock it by turning the hex nut counter-clockwise (pictured above).
- Once unlocked, you can adjust the hardness of the product water by turning the blending valve counter-clockwise. 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.
- 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 is considered CLOSED - meaning you aren't letting hard water in.
