14 Miracle Water Installation & Operation Manual
Step 5. Cold Water Pipe Grounding
WARNING: The house cold water pipe (metal only) is often used as a ground for the house
electrical system. The 3-valve bypass type of installation, shown in Figure. 2,
will maintain ground continuity. If you use a plastic bypass valve at the unit,
continuity is broken. To restore the ground, do the following.
Install a #4 copper wire across the removed section of main water pipe, securely clamping at both
ends, see Figure 9 (parts not included).
NOTE: Check local plumbing and electrical codes for proper installation of the ground
wire. The installation must conform to them. In Massachusetts, plumbing codes of
Massachusetts shall be adhered to. Consult with your licensed plumber.
Step 6. Install Valve Drain Hose
NOTE: See valve drain options on page 11.
1. Connect a length of 3/8” or 7/16” I.D. hose (check codes) to the valve drain elbow, on the con-
troller, see Figure 4. Use a hose clamp to hold the hose in place. Route the hose out through the
notch in the Faceplate Cover.
2. Run the hose to the floor drain, and as typically shown in Figure 2, tie or wire the end to a brick
or other heavy object. This will prevent ‘‘whipping’’ during regenerations. Be sure to provide a 1-
1/2” minimum air gap, to prevent possible sewer water backup.
NOTE: In addition to a floor drain, you can use a laundry tub, or standpipe as a good drain
point for this hose. Avoid long drain hose runs, or elevating the hose more than 8’
above the floor.
Step 7. Install Salt Storage Tank Overflow Hose
1. Connect a length of 3/8” I. D. hose to the salt storage tank overflow elbow and secure in place
with a hose clamp (see Figure 2).
2. Run the hose to the floor drain, or other suitable drain point no higher than the drain fitting on
the salt storage tank. (This is a gravity drain.) If the tank overfills with water, the excess water
flows to the drain point.
NOTE: Route the tubing neatly out of the way and cut it to the desired length.
DO NOT connect the valve drain tubing from step 6 to the salt storage tank over flow hose.
