Probably some pipe rust clogged the exit. If u have pretty low pressure on one or both, hot and cold water, try keep force closed by hand the water exit at shower pipe, then start both cold and warm water gradually as much as u can keep it closed with the hand.The pressure of the water will try "escape thru the clogged pipe and hopefully unlock that debris or rust!The hot water pressure going back thru the cold water pipe might unclog that debris.Just a simple fix which many times works as a charm..Otherwise if this is not fixing, try close both water from main service valve. Then unscrew the secondary shower valves and manually clean them or replace if very damaged.

The problem is not likely battery related. It sounds like either an ignition or fuel control relay that is not actuating due to missing electrical voltage.

It is highly unlikely that the faucet failed; it's far more likely the feed tube between the water pipe and the faucet burst. If your faucets were installed 5 years ago, it's likely that they were installed with flexible feed tubes. Reach up under the faucet and unscrew the feed tube, then unscrew the feed tube from the cutoff valve on the water pipe. Take the burst tube to Home Depot and get a new one - it should cost $10 or so. (I would also recommend picking up a small tube of thread seal - it'll look like a travel tube of toothpaste and cost about $3.) Lightly coat the threads of the faucet connection with thread seal and screw the feed pipe onto the faucet as tight as you can with your hand. Do the same at the cutoff valve end with a wrench but do not over tighten. Once both ends are firmly connected, turn the cutoff valve on and check for leaks. If you find any, try to tighten the connections a bit. If you're uncomfortable with any of this, I'm sure there's a DIYer like me in your neighborhood who'd be glad to help out. It's easy and it's quick once you've done it a couple times. Good luck!

There is definitely a problem with the cold valve if it is leaking, but it seems odd that it doesn't leak when it is on. If I was doing this, I would replace both valves.

they are normally held on with two screws to the valve.

The Kohler 7.5 R had a possible three different voltage regulators that could be used. You need to check there first. Also if you can get it the service manual for these are tp-5110 Which will show you how to test the regulator o the bench. There was a 5 6 and 7 pin regulator that could have been used.

check diodes on main control board. they short out if something went wrong.

You probably have one of the newer Cimarron-series toilets that feature what Kohler calls "AquaPiston" technology. These gadgets use the water pressure in your supply lines to pressurize a charge of flush water in the tank, causing the flush water to rush into the bowl at high pressure and velocity. Many Cimarron-series toilets use only 1.28 gpf (gallons per flush), compared to the current industry standard of 1.6 gpf for conventional gravity-flush units. Reducing the gpf rating by 20% requires pressurizing the water in the tank, and the release of pressurized water makes a lot of noise. I'm afraid your toilet will always be noisier than what you may be used to.

That faucet has a lifetime warranty. Call Kohler (1-800-4-Kohler) and tell them you need a new cartridge for a K-10270 faucet.

They make an extraction tool called a grabitz
It's a double ended tool which has sort of drill on one end and an ez-out on the other. Use the drill end first then the other with drill in reverse usually will come right out. And put some grease on the new screw before installation and won't have that problem next time

-Only at the sink has no hot water...? If yes then: -Make sure the valve on the wall is Turn On. -If not sure which way then turn faucet on and then turn the vale on to either side to find out. Good luck Mai
