If your source water has naturally high Calcium Hardness, you can manage it with a stain and scale control product. Add Calcium Hardness Increaser to raise Calcium Hardness levels in your pool. If your water is soft, meaning levels are below 150–180 ppm, this can cause aggressive water conditions known to cause etching, staining, and mineral deposits. The ideal range of 200–400 ppm is somewhat flexible, as many pools operate with much higher Calcium Hardness levels without a problem. Calcium Adjustments: For pools in hard water areas, tap water of 400–600 ppm is not uncommon.Use pH Increaser or pH Decreaser as needed to maintain an ideal pH level of 7.4–7.6. On the other hand, when pH rises above 8.0, chlorine is very slow to react, and the water becomes very basic, making it prone to cloudy water conditions and scale deposits. But when it dips below 7.0, the water becomes acidic and slightly corrosive. pH Adjustments: When pH is slightly low, your chlorine works well.If your TA is above 120 ppm, use pH Decreaser to reduce levels within the ideal range of 80–120 ppm. If your TA is below 80 ppm, add Alkalinity Increaser. Alkalinity Adjustments: It's recommended to start with any adjustments to Total Alkalinity (TA) first, because of its effect on pH levels.If installing on 4-11 box, see the larger plaster ring for 4-11/16" junction boxes.Ĭlick Electrical Switches, Toggles, Outlets, Dimmers for Switchplates for electric devices in black, brown, gray, white, ivory, light almond or red. This 1/2" raised ring fits the same boxes and devices. NOTE: Main photo only shows product extra photos showing a flat ring for usage examples only. Guide for Covering Centered Switches - make sure to order the right mud ring and cover for your specific electrical box.Use mudring when only one electrical switch is to be mounted in the center of a double gang box, either for aesthetic reasons or when extra mounting room is needed.
Mud-ring works with all standard devices - decorator rocker switches, toggle switches, dimmers and duplex outlets.1-15/16" wide opening in center vertical center screw holes spaced at 3-9/32" apart center to center (standard box mount).device mounts onto raised plaster ring and switch plate mounts onto device.screw holes for centered devices fits on 2 gang electrical square boxes (4-1/4" x 4-1/4").heavy duty galvanized steel 4.25" x 4.25" raised plaster ring with 0.5" deep flange to lift devices up from electrical box Mulberry, UL listed.Fits an electrical square box for mounting decorator rocker, GFCI, toggle, duplex outlet, or intercom devices in the middle. Use anywhere bulky, behind-the-scenes wiring requires the use of a two gang electrical box to accommodate all wires in a home or office building such as smart tuner keypad or speaker installation in high-end multi-room audio sound systems, whole-house digital entertainment systems, intercom communications networks (such as those by Russound). This two-gang mud-ring fits on boxes that are recessed in the wall after drywall or plaster was added and is designed to lift the electrical devices up and flush with the wall surface. Surface mount electrical devices on 4x4 box with 1/2" raised mud rings for center mount switches and wall plates.
