Screw Tight® skimmer covers are designed not only to allow you to easily stop
the flow of water into your pool's plumbing system, the smaller opening helps to
protect children from getting hands caught in the suction of the pump. Screw
Tight Skimmer Guards also restrict and speed up the flow of water into the skimmer
box during filtration. The scientific principle behind Screw Tight’s smaller opening
states that when a given amount of liquid is made to flow through a smaller opening
in the same length of time, it must flow faster. Faster flow ensures a stronger
current. We have all seen this principle at work in a wide slow moving stream
or river that comes to an area where the water must flow through a narrow section.
The water flows much faster and a strong current is formed in the narrow section.
It’s the same amount of water flowing through but it flows faster to get through
the smaller opening between the rocks. A helpless boater caught in this strong
current is now unable to maneuver his boat to either side and safety, when a few
minutes earlier in the slower moving water, he could have easily paddled to shore.
This stronger faster moving current flowing into the pool’s skimmer box opening
will naturally draw more floating debris from further away into the skimmer box.
This means the pool will be cleaned better and more thoroughly in a shorter amount
Here is another plus. The faster current flowing into my Screw Tight® skimmer faceplate spillway also helps to trap and hold frogs, toads and other small furry critters that find their way into the pool. Once in the skimmer box, they are trapped by the current and held harmlessly in the skimmer box. To remove these critters from the skimmer, just turn off the pool’s pump. The flow of water will stop and the skimmer’s float operated trap door will swing up and close. The skimmer basket with its load of critters can then simply be lifted out of the skimmer box and its yucky contents discarded.
The clean, white, attractive faceplate of my Screw Tight® unit attaches to the pool wall using the same screws, screw holes and gasket originally used. New gaskets are available if your old gasket is damaged or in need of replacement. It only takes couple of minutes to install the faceplate with its large round center spillway hole. The round threaded hatch cover then just slips into the spillway hole of the faceplate and screws in tight. An O-ring in the lip of the cover makes a watertight seal everytime that holds fast. When maintenance requiring closure of the skimmer box is accomplished or in spring when the need for winter shut down is over, just unscrew the hatch cover and remove. Screw Tight hatch cover is made of heavy-duty, cold weather safe, bright white plastic with a flexible rubber O-ring gasket. There is even a special slot on the hatch cover handle to allow any long thin tool like a screw driver or wrench handle to be inserted to apply extra turning power if you want.
Take a look at the pictures and see how easily my new cover works. The rectangular faceplate measures 8-1/2" x 10-5/8" with a 5-1/4" diameter round flow-hole in the middle. Screw Tight® Skimmer Guard and Critter stopper is made to fit the standard rectangular skimmer hole openings of most in ground pools. To check your pool for fit, measure the distance between the corner mounting screw holes of your pools skimmer box opening. Measure diagonally from one top corner screw to the opposite lower corner screw. The holes should be 11-3/8" from the center of one hole to the center of the opposite diagonal corner hole. Just remove the screws and the existing skimmer box faceplate with a screwdriver. Use the same screws and the same gasket to reinstall your new Screw Tight® faceplate. You’re done. When you need to shut off the skimmer box water flow, simply turn off the pump, shut off the electricity to the pool at the fuse box and screw the round hatch cover into the flow hole of the faceplate. Tighten only hand tight with any long thin tool held in the oversize slot on the hatch cover. Don’t over tighten this great new cover. The screw threads and rubber gasket do the work for you.
Additional Security Even with a Screw Tight® skimmer guard, it is possible for water to enter your skimmer box from above through the crack around the edge of the skimmer lid or through the hole in the center of the skimmer lid. A good item to use as additional safeguard against freezing water damage is a Gizzmo. The Gizzmo is a hollow plastic plug that screws into the outlet at the bottom of the skimmer box. Just seal the threads of the Gizzmo with plumber’s silicon tape and screw it into place in the center of the skimmer box. This will keep any water from entering the plumbing at the bottom of the skimmer box. It will help guard against freeze damage by compressing when the water freezes instead of the walls of the skimmer box giving way and expanding outward. Two sizes of Gizzmo are available. Ask your pool specialist for the size Gizzmo that is right for your pool.
