Turn off the water supply to the Jacuzzi and locate the bolts on the underside of the rim. Tighten the bolts holding the Water Rainbow to the edge of the Jacuzzi with a socket wrench if they feel loose.
Tighten the bolt connecting the plumbing pipe to the underside of the Water Rainbow if it is the source of the leak. Failing to properly secure this nut could cause water to drip under the faucet.
Inspect the elbows and joints in 5/8-inch OD copper pipe connecting the Water Rainbow to the plumbing for pinhole fractures. Fitting a sleeve over the damaged area seals the leak without the need to replace the section of pipe.
