The cartridge just needs to be turned 180 degrees to put hot and cold on respective sides. As far adjusting temp., right behinde handle there should be two pieces bigger one goes in first. The smaller of the two is more ring like with a sqare on top, the more the sqare is rotated to the left, the more the handle can turn to the hot side of valve. I hope that makes sense.

Typically the Hot Should show on the left and the cold on the right when facing the faucet. If the plate reads the other way, I would try exchanging it first or utiize flexible connectors and cross them.

Remove the handle and bezel (face plate). Locate adjusting screw and turn right (counter-clockwise) to increase temp. or left (clockwise) to decrease. Check for desired temp before replacing face plate.

I have a pioneer shower valve that has pressure problem

The way anti-scald valves work is there is a slide tube inside the faucet which requires pressure from both hot and cold or else it will cut off the flow. As for temperature adjust I do not believe there is an adjustment screw but more so there are these white plastic toothed stop rings which prevent the handle from turning 360 degrees. When your adjust the stop ring, it adjusts how much hot water is allowed to mix with the cold water. My wife likes her showers a lot hotter than I, so I gave a good allowance with the stop ring. The "adjustment screws" which you are viewing are not for adjustment of temperature, they are remote cut-off screws to stop the water entirely to change the washers in the unit if needed. SO open those all the way and leave them open. Think of them as not having to go all the way into the basement to shut off the water supply just to change a few washers.

How to fix a Toto Clayton shower valve with

I have the same problem on my shower. There is a cover plate on the hot/cold handle that will reveal a screw. Unscrew the cover plate by hand, then the screw using a philips head. Once you have the hot/cold handle off, you will need to unscrew the cylindrical cone shaped canopy and ultimately the cover plate (which says Toto / Hot / Cold / Tub / Shower on it).

Looking in at the screws from the shower side, first, check to see if you can feel any threads sticking out from either adjuster. Try to set them the same. Counter clockwise will give you more water from the pipe you adjust. If either of your pipes are smaller or filled with more corrosion than the sink pipes, you will have impared flow. If adjusting the valve doesn't give you the desired temperature, if you have the ball type valve, the seals need to be replaced. If you have the cartridge type valve, the cartridge needs to be replaced.

Not alot of hot water?

1st Check the temperature restricting coller behind the cover under the handle. It is used to restrict the flow of hot water to stop you from being scaulded.
2nd Those set screws will control the flow. Check to ensure both sides are open the same amount of turns. If the water pressure is good turn in the cold side.

Water is either hot or cold - no in between.

I found a way to get warm water in the shower, but I'm not sure it qualifies as a solution. After trying everything else I thought that maybe when I was feathering the faucet in the shower toward the cold side so I would get warm water that at a certain point it blocked the flow on the hot water side enough so that the sensor in the hot water heater sensed there was no demand in the line and it shut the water heater off. To test this, I went to the kitchen and turned the kitchen sink faucet all the way to the hot side and then turned it on so that I got a small flow of water. I waited for the water to get hot to be sure the hot water heater was working. Once it was hot, I left it running to keep demand in the line and then I went to the shower and turned the faucet on. When the water got hot I started feathering the control towards the cold side and soon I had warm water. So I think I'm right in that the sensor in the hot water heater was shutting the water heater off when the demand in the shower was lowered to a certain point when I was trying to adjust the water temp in the shower.

So now I can get warm water, but it means I have to leave the hot water running at another fixture in the house to create a false demand in the system so the hot water heater doesn't shut down. Is there a way to adjust the senor in the hot water heater so that it will stay on when I'm using the shower only, so I don't have to waste water by running another faucet when I want to take a shower?

Not enough hot water

Some higher end models do have an adjustment that is behind the face plate. You would have to remove the handle and the screws in the faceplate to expose them. If you have adjustments they will be located on the brass valve body facing you. You will need a flashlight and a flathead screwdriver to make the adjustment. If your model is not equipped with adjustments you could have a faulty valve stem. The stem is comprised of a rubber band like gasket that separates port holes into which the waters flow. There could be some piece of trash blocking the port not allowing adequate water from the hot side into the valve.Some valves stems are also able to be installed upside down causing the same issue as the ports do not rotate fully to allow adequate supply. However you say that you have adequate pressure on the hot side but not warm enough. There is another possibility also based on the way the shower supply was plumbed but there is no need to go into this unless this does not resolve your issue. I hope this is of assistance and thanks for using Fix Ya. Please let me know if I can be of further assistance.
