How do you remove Jacuzzi Waterfall handles to get to the valve. There are no visible screws??

There may be a video but you should be able to tell by looking at it too

TURN BOTH HANDLES TO THE FULL OFF POSITION THEN REMOVE THE RETAINING SCREW PULL THE HANDLE OFF AND RE POSITION THE HANDLE TO MATCH THE OTHER HANDLE

Spray with lubricant and let it work - you may have to spray more than
once - main thing is do not strip the screw head....try a long handled
screw driver.

Here is a link to a site that sells jetted tub cleaners.

Any of these cleaners work very well at removing the smell from a jetted tub and the bacteria in the pipes as well.

Shut water off and remove knobs. Replace valves on side leaking. Go to Home Depo they will help.

To set the shower valve handle limit stop, remove the screw holding on to the handle and remove the handle.

Remove the round dome cover by turning in a counter-clockwise direction. At this point you will see a small slotted screw head that is visible in the valve cap.

Place the handle back on the valve stem (loosely) and open the valve turning the handle until the maximum desired position is reached. This may require turning the limit stop screw (T-34) counter-clockwise (see CAUTION above). To most accurately and safely verify the temperature of the hot water, place a thermometer in a tumbler of water filled from tub outlet.

Shut off valve and re-attach dome and handle.

There is a cap on the top of square knobs that you have to pry off with a tiny thin blade. Under that cap is a screw that will allow you to remove the knob.

On this valve the hot/cold in reverse is easy enough to fix, but the faucet dripping at the handle is another issue. To reverse the hot and cold, turn off the house water, relieve the pressure by opening a nearby faucet. Once the water stops, remove the handle and faucet cover so you can see the valve. then the four screws that are visible need to be removed. Mark one of the screw holes with a crayon or pencil and then remove by pulling straight out. Once out, inspect the main o-ring right behind where it sits against the valve, (if this is damaged, it might be why the handle area is leaking) then turn the whole assembly clockwise 180 degrees then insert straight back in and insert screws. Tighten screws until snug. Turn water back on before installing cover and handle to check for leaks. If no leaks are found, install cover and handle and check for proper position of hot and cold. If there are leaks, tighten screws in clockwise rotation tightening each screw a quarter turn, then moving to the next one until dripping stops. If dripping is from center of stem, where the handle attaches, you will need to contact Price Pfister to request a replacement. They are very good to work with. Good luck.

You have two options. You can either replace the faucets- which is much easier for a novice, or you can rebuild them. As far as removing the handles, double check and make sure there is no set screw. If there is not, then the handles should come off. You may have to gently rock each one from side to side. Once you get the handles off, you should see where the valve unscrews. Now would be a good time to turn off the main water going to the tub. Once that is done carefully unscrew the valves and remove them. Take this to Lowes or Home Depot and you should be able to find repacking kits. They usually have full installation instructions included.

You can drill a small hole into the set-screw and use an easyout to extract the set screw
