King Technology In Ground Tune-Up Kit, 2940225

The King Technology in ground tune-up kit gathers the wear pieces for a seasonal service into one package: silicone lubricant, a control dial o-ring, a knob with its o-ring, a cap o-ring and the control dial snap ring.

What it fixes

Almost everything that goes wrong with a unit like this comes down to seals. O-rings flatten, harden and take a set. Once they do, the dial gets stiff or stops holding its setting, and water finds its way past the cap. Replacing all of the seals at once is far quicker than chasing them one at a time, which is what a tune-up kit is for.

Use the lubricant

The silicone lubricant is in the kit for a reason. A dry o-ring can roll or pinch as it goes into its groove and then leak from day one. Lubricate every seal before it goes in, and take the extra minute to wipe the grooves clean first.

Match the version

This is the in ground kit. There is a separate kit for the above ground unit, so check which one you have before ordering.
