A great new way to hide power cords!
Even the nicest water feature installation can be ruined if the cord for a pump or a light is visible, as they often are. Power cords should be removable, so that lights or pumps can be serviced or eventually replaced. They can’t just be buried away in concrete. With open reservoir water features, like ceramic vases or copper basins, a hole in the reservoir that’s big enough to pass a plug is hard to seal, and cutting the plug off voids the warranty on pumps and lights.
Wouldn’t it be great if a power cord could pass through the same bulkhead fitting that the water feeds through? Without leaking? That way, a light could be set inside the reservoir without a cord draping over the edge, or a pump cord inside a basin could pass through a plumbing fitting, virtually invisible. But, even if you ran a cord inside a pipe from inside the reservoir, how would you get it back outside of the pipe, outside of the reservoir?
Enter the CSF. The Cord Seal Fitting is a nifty gadget that addresses that particular need, to pass a cord through the wall of a reservoir inside the fitting or pipe that is the reservoir’s only perforation. It works much like a plumbing pressure test plug. A rubber gasket squeezed between two plates expands outwards and seals off a 1-1/2″ female socket. But, unlike a test plug, the rubber doughnut is slit to its center to accept a standard light or pump cord. The plates on either side of the gasket are also split, to assemble around the cord and gasket like the cookies around the creme of an Oreo. When tightened, the rubber expands tightly around the cord and into the fitting, creating a waterproof seal.
As is often the case, the Cord Seal Fitting is far easier to use than to describe. Install a tee in the 1-1/2″ waterline feeding the reservoir and pass the cord through the tee and into the reservoir. Loosen the plates on the CSF, slide the cord into the gasket, reattach the plates and tighten the CSF in the opening of the tee. The gasket will expand and seal against the cord and the inner walls of the tee.
The CSF will also allow the cord to pass in and out of a sealed section of pipe, with the addition of a second tee. This is useful where a pump may be hard piped from the inside of a reservoir, out through a bulkhead fitting and up to a spillway. The illustration to the right shows the pump cord passing out of the reservoir through tees through a tee installed on either side of the bulkhead fitting and sealed with Cord Seal Fittings inside and out.
