Back-to-back installations require that the pressure balancing cartridge be "flipped" or rotated 180 degrees in order for both units to function properly. Flipping the cartridge will reverse the hot and cold water supply lines so that the faucet works like a traditional hot/cold unit. The cartridge may also be flipped to correct a hot/cold reversal resulting from connecting the supply lines to the incorrect sides of the valve.
There are two types of valves. Choose A or B below depending on your series
A. 1300/1400 Series (RP19804)
Watch this how-to video or follow these steps:
Let the water run until both hot and cold water is fully mixed.
Rotate the handle fully counterclockwise to the hottest position.
Place a thermometer in a plastic tumbler, and hold the tumbler in the water stream.
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:
a. 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.
b. 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 2º F. NOTE: If water temperature is too cool, rotate the limit stop counterclockwise.
The spool and sleeve, the part of the Monitor pressure balance valve that blends the hot and cold water, may not be working properly. This can be caused by mineral deposits that build up over time, resulting from hard water. To solve, follow the steps below based on your model.

There are two types of valves. Choose a or b below depending on your series
1300/1400 Series: Remove handle.
1700/1800 Series: Remove temperature knob, cover and handle.
Twist and pull sleeve to remove it.
Unscrew brass bonnet nut.
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.
Before removing valve cartridge assembly for any maintenance, be sure to note the position of the stop on the cap. The valve cartridge assembly must always be put back in the same position. For normal installations, the stop on the cap will face the left.
BE SAFE! After you have finished the installation, turn on valve to make sure COLD WATER FLOWS FIRST.
A small gap is normal and necessary to allow proper movement of the handle without damaging the escutcheon below it. An excessive gap results from improper height adjustment at the time of installation. To fix it:
Loosen the nut under the counter/sink.
Then screw the escutcheon UP just enough to make up the gap.
Then re-tighten the nut. This lowers the valve and reduces the gap
Some common tools include:
Please refer to the Maintenance & Installation Sheet supplied with the faucet to make sure you have all the necessary tools. If you need a Maintenance & Installation Sheet for your faucet, visit the Online Catalog and search for your faucet. When your faucet appears, select the Maintenance & Installation option to view the installation information.
Delta Faucet Company recommends you leave the existing fitting on the PEX supply tubing and not shorten the tubing. If you determine the PEX supply tubing for this faucet is too long and must be shorter to create an acceptable installation, be sure to read the instructions and plan ahead. When cutting the supply tubing, the installer accepts the responsibility to do so in a way that allows a leak-free joint to be created. Delta is not responsible for tubing that is cut too short or cut in a way that will not allow for a leak-free joint. For custom fit installations, you must use RP50952 sleeves supplied with model and nuts included on supply lines. Tube cut must be straight. See plastic sleeve installation instructions found on RP50952.
NOTICE: DO NOT use a metal sleeve, RP51243 gasket (supplied with faucet) or ferrule in the place of the plastic sleeve supplied--it may not create a leak-free joint. Do not use pipe dope or other sealants on water line connections.
Instructions: Watch this how-to video for information on how to cut your PEX supply lines to size.
1. Identify desired length of tube (1). Leave 1" - 2" of extra length to allow for easier installation, and cut tube. Ensure cut is straight and burr free.
2. Slide nut (2) and plastic sleeve (3) onto cut tube. Ensure sleeve is oriented as shown.
3. Insert tube into outlet fitting (4). Tube should touch bottom of hole inside fitting.
4. Slide plastic sleeve down tube until it engages top of fitting. NOTICE: Failure to use plastic sleeve in the correct orientation will result in disconnection and possible water damage.
5. Slide nut over plastic sleeve. With wrench, tighten nut 2 turns past finger tight. Do not overtighten.
The faucet is in the wrong position.
