How do I change jets in bathtub? - Kohler 1107-R-0 ProFlex Bath Tub with Flange and Right Hand Drain Finish: W

Cleaning your Tub
There are several options for cleaning the piping on a jetted bathtub.
The reason you have a residue on the bathtub surface when you are done bathing is because there is bacteria built up in the plumbing of the jetted tub. In order to remove that and reduce the amount of "yucky stuff" coming into the tub when using it, we recommend a regular usage of a jet cleaning product about once every couple of months
Here is a link to the cleaning products I can find right now. There may be other out there that I am not aware of but I do know these products work well in all jetted bathtubs.

The gasket around the jet may be leaking because it is deteriorating or the flange nut on the outer side of the jet has loosened up. Check all jets for loose hardware.

no such items exist. use it like a jetted bathtub or pull it out and put in a soaker tub.

yes jet trim can be changed. Go to this link and match up what you have to what is shown online or email us a photo of the items and we can find them for you. each trim piece usually unthreads counter clockwise.

the bathtub needs to be full.  and you can turn the jets on some modles.  old homeowner new this and probably turned the jets up so it will do that not really funny.  

call whirlpool or go to local bath and kitchen shop or local plumbing store. they should be able to give a price and tell you how to change all of the items.
