The insert that came with the valves says the time is not adjustable, BUT it is! You could improve the insert/instructions by including the following information: Adjust the time the valve is open using the enclosed allen wrench, inserted into the small hole in the front of the valve button. (The little allen wrench supplied for adjusting the time is 1.25 mm, or .050", or 1/20". This size is not found in any standard Allen wrench sets, Metric or SAE, so don't throw it away or lose it!). The allen head time adjusting screw it fits into, inside, turns with the access hole, when you turn the temp adjustment. Turning the allen wrench Left is Longer valve open time, Right is shorter valve open time. One full turn is about 5 seconds of time adjustment.

There was no insert/instructions with the replacement cartridges. It would help if you gave basic instructions on how to replace the cartridge: Turn off the water and relieve the pressure in the system, loosen the top & bottom allen head retaining screws at the back of the valve body to allow the cartridge to slide out, unscrew/remove the 2 turning stubs, remove the 2 allen head set screws that hold the collar, remove the collar, pull the cartridge out, using an adjustable wrench, remove the threaded steel sleeve from the old cartridge, apply plumber's grease to all rubber seals and O-rings including under the perforated plastic end cover/sleeve on the new cartridge, thread/install the steel sleeve onto the new cartridge hand tight, install the prepped cartridge into the valve body, tighten the rear retaining screws, install the collar and set screws, install the turning stubs. Turn on the water. If hot is cold and cold is hot, the cartridge is in upside down. Turn off the water, remove the cartridge, turn it 180�, reinstall it and turn the water on. Adjust the time using the enclosed allen wrench, inserted into the small hole in the front of the valve button. See time adjustment instructions above.

The SLHVE shower faucets just dont seem to be durable enough for frequent use, and had to replace o-rings and cartridges often, but since I put signs as to how to use the push button faucets it did seem to help. King Supply did A very good job at replacement and had my customer up and running again.. Thank you for the great service and will use King supply in the future!
