I have an American Standard elite whirlpool tub moderl #2425ERHO020 from 2004. One of the side jets (next to the outside wall) is leaking and dripping down on the celing below. I have cut a hole in the ceiling and have pretty much identified that it is the jet or jet pipe. I need someone to fix it for me in the Portland, Or area.

Yellowing is a sign of age, but plastic items can be brightened up a bit. Here are some suggestions:

Not normal for that to happen but the jet faces on the two back jets may be turned off or down.
Try turning the face of the jet clockwise and see if you get more water flow out of each jet.

The workings of a bath jet...From the inside of the Bath there is a wall fitting that threads from the inside of the tub into the jet body located on the outside wall of the tub.
If the jet is leaking at this point behind the tub then you should take the wall fitting out of the tub and put a small bead of 100% RTV silicone around the flange of the wall fitting and reinstall it.
If however, the leak is from the PVC piping going into the jet then you will need to replace the jet.

sounds like maybe the jet faces are turned off. see if they turn one way or the other and they may open and spew water out for you.

Jet trim usually unthread counter clockwise out of the wall fitting

The jets have a nut on the back of the jet. I hope you have access or else you will need to pull the tub for this job. Loosen the nut and squeeze aquarium grade silicone in between the tub wall and the nut, Tighten the nut, but not to tight. Let set over night fill and check for leaks the next day.

Sorry, the tub will have to pulled out to find out what is leaking so it can be fixed. There is just no other way UNLESS you can open up the wall on the blind side of the tube. (but its probably and exterior wall...if the house is vinyl sided, it can be done. If brick, you'll have to pull the tub). If you just wanted to convert to a tub only, maybe Bathfitters has an insert solution...

This is a hard fix, The jets are glued on to the back of the tub with an epoxy type material. the jets should spin on and off from the inside of the tub. You need to determine if it is the hole where the jet is that's leaking or if it is the jet assembly and tubing that is leaking. If it is the jet hole that is leaking, spin the jet off and use aquarium grade silicone (Lowes carries it)
spread this around the piece sticking thru the tub and spin the jet back on. This is a hit or miss fix. No easy fix if it is the tubes or jet assembly, full access necessary for this repair.

Check the air vacuum switch and line as you may have a air vacuum leak. The button that controls the on and off to the jets is an air vacuum switch....It may have a slow air leak in the line or connections that is activating the on and off control
