    Brand new faucet. No mineral deposits.

    seals and springs are good. I can reverse hot and cold but not getting pressure from one or the other. Both are on.

    Picture is helpful.

  • The spool and sleeve, the part of the Scald-Guard pressure balance valve that blends the hot and cold water, is not working properly. This can is caused by mineral deposits that build up over time resulting from hard water. To fix this, follow the steps below based on your model.
  1. Shut off water supply.
  2. There are two types of valves. Choose one or the other below depending on your series.
  • 1300-1400 Series: Remove handle.
  • 1700-1800 Series: Remove temperature knob, cover and handle.
  1. Twist and pull sleeve to remove it.
  2. Unscrew brass bonnet nut.
  3. Remove cartridge.
  4. Soak cartridge in a 50/50 vinegar and water solution for 24 hours to remove any mineral deposits.
  • **NOTE** Unless both hot and cold water supplies are turned on, the pressure balance valve will allow only a dribble of water to flow through the valve.
  • I have put up a picture to make disassembling it just that much easier for you.

    • Oh, I didn't know it was new. That's kind of important information because new = installation problem.

    • Go through these steps again. These faucets have to be installed just so or they will not work properly.

    1. Let the water run until both hot and cold water is fully mixed.

    2. Rotate the handle fully counterclockwise to the hottest position.

    3. Place a thermometer in a plastic tumbler, and hold the tumbler in the water stream.

    4. If the water temperature is above what is allowed by your local plumbing code -110º F or 120º F, remove the handle on 1300-1400 series or temperature knob on 1700-1800 series, and rotate the rotational limit stop.

    • Counterclockwise if you have a Monitor 1300 or 1400 series model, handle controls the temperature only, not the volume. For every tooth the rotational limit stop is rotated counterclockwise, the maximum water temperature will decrease approximately 6º F. NOTE: If water temperature is too cool, rotate the limit stop clockwise.

    • Clockwise if you have a Monitor 1700 or 1800 series model-handle controls volume; temperature knob controls temperature-. For every tooth the rotational limit stop is rotated clockwise, the water temperature will decrease approximately 2degrees F. NOTE: If water temperature is too cool, rotate the limit stop counterclockwise.

    1. For 1300-1400 series: Replace the handle. After verifying the water outlet temperature, secure the handle with the screw. Do not over tighten. For 1700-1800 series: After verifying water outlet temperature, snap temperature knob into place.

I have a Delta scald guard shower faucet (older model). The cold water pressure is good but as a turn to hot the pressure drops to a drizzle. There are 2 other sinks and another shower upstairs and there...

It is more that likely the valve in the stem of your fixture, I'm assuming this is a single handle faucet. If you can replace the valve, you will cure your problem. I am giving you a link to how to adjust the hot water temp.

I have two vanities and a shower in the bathroom. We only get hot water to the sinks when we turn on the shower to hot. Even if we turn off the shower we will still get hot water for a while. It just seems...

Check the water supply lines to the shower at the faucet handles. If the fitting for the hot water line connected to the handle is loose, it can twist and kink off the water supply further down the line when you turn the faucet handle. I'm not exactly sure how this could be relevant otherwise, but under normal design circumstances this type of scenario with your shower wouldn't matter for other faucets.

Shower/tub combo hot water problem

There is a restriction in the faucet or the piping to the faucet on the hot wtaer side...this will be very hard to find and fix... The shower uses less water so it will get hot.... the tub spout allows more water flow so you cannot get the water more then warm...

Take the faucet apart and blow out all the passage ways with air... also run some water from the piping while the guts are out of the faucet, to flush the piping...
Hopefully this will fix you up...

Pulsating water and poor hot water pressure

Based on your description it sounds like the pressure balancing valve could be gunked up with particulate from your well or just worn out. If your water is not filtered to that shower I would lean more towards particulate. Try to remove the cartridge and take it to a plumbing parts store for a match-up since Delta makes several cartridges and you want to get it right the first time.

Water is not very hot.

First try adjusting the pressure balancing gear located right behind the handle. If you still do not have hot water I suggest to replace the cartridge.
