Nothing is wrong with your faucet. The shower head is simply emptying its reservoir of water.

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 is often caused by mineral deposits that build up over time. To solve, follow the steps below based on your model.

Tools you may need:

1. Shut off water supply.
   
   
   

2. There are two types of valves. Choose a or b below depending on your series

   1. 1300/1400 Series: Remove handle.

   2. 1700/1800 Series: Remove temperature knob, cover and handle.

3. Twist and pull sleeve to remove it.

4. Unscrew brass bonnet nut.

5. Remove cartridge.

6. 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.

Helpful Hints:

1. 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.

2. To remove valve cartridge from body, shut off water supplies and remove handle and bonnet nut. Do not pry the valve cartridge out of the body with a screwdriver. Place handle on stem and rotate counterclockwise approximately 1/4 turn after the stop has been contacted. Lift valve cartridge out of body.

3. To remove seats and springs, remove valve cartridge. Separate cap assembly from the housing assembly by rotating the cap assembly counterclockwise 90 degrees. Separate cap and housing assemblies. Remove seats and springs and replace. Place the largest diameter of the spring into the seat pocket first and then press the tapered end of the seal over the spring. Reassemble valve cartridge and replace in body following instructions given in 1 above.

4. If the water in your area has lime, rust, sand or other contaminants in it, your pressure balance valve will require periodic inspection. The frequency of the inspection will depend on the amount of contaminants in the water. To inspect valve cartridge remove it and follow the steps in note 1 above. Turn the valve to the full mix position and shake the cartridge vigorously. If there is a rattling sound, the unit is functional and can be reinstalled following instructions given in note 1 above. If there is no rattle,replace the housing assembly (RP19805).

You need a new cartridge assembly, part number RP19804. You may notice that the new one will be blue and white while yours may be white. This is just a change in manufacturing which will not affect your ability to use it.

First, we need to find out if the hot or cold valve is causing the leak. Let's begin by troubleshooting with the hot valve:

1. Shut off the hot water supply. If you can't find the shut-off for your tub/shower valve, shut off the water to your house by using your water shut-off valve.
2. Remove the faucet handle. To do this, depending on your handle type, you will need a Phillips screwdriver or an Allen wrench.
3. Remove the chrome bonnet nut using an adjusting wrench.
4. Remove stem extender.
5. Remove stem assembly by pulling straight out.
6. Remove the extender and stem assembly.
7. Remove the seats and springs.
8. Examine them for wear or debris and wipe out any debris in the depression where the seats and springs sit in the valve body.
9. Replace the seats and springs. (Delta Genuine Part RP4993 -€“ two sets per package).
10. Reassemble the faucet to see if the drip has stopped.

If the drip persists, repeat the above steps on the cold valve.

If you've replaced the seats and springs and the problem continues, replace both stem assemblies (Delta Genuine Part RP1740 - one stem assembly per package).

If all of the above has not fixed your leak, and your valve is more than 10 or 15 years old, it is possible that the actual faucet body may have developed a leak. If so, you will need to replace your tub/shower valve with a new one.

It is normal for a small (pencil thin) stream of water to continue to flow from the tub spout when the shower is in operation. If the amount of water flow is excessive, then this indicates a problem with the diverter located in the tub spout. This cannot be repaired and the spout must be replaced. Remove the tub spout and replace it with a Genuine Delta tub spout.

To locate a local source for Delta tub spouts, contact licensed professional plumbing contractor or Delta showroom, or call 1-800-345-DELTA (3358), or e-mail us for assistance.

Note: Consumer safety is our number one concern. If you do not have experience with plumbing repairs, we recommend that you contact a licensed plumber for tub/shower repairs.

If this is a non-pressure balance tub or shower:

On a single handle tub or shower, you need to tighten the adjusting ring or replace the cam and packing.

1. Tighten the adjusting ring until no water leaks around the stem when the faucet is in the full on hot and cold mixed position and pressure is exerted down on the handle.

2. Loosening and tightening the adjusting ring also controls how hard or easy the handle is to use. Over tightening of the adjusting ring can cause premature wear of the seal surfaces necessitating frequent repairs.

If leak persists, you may need to replace the cam and packing using Delta Genuine Parts.

1. Shut off water supply.

2. Cover drain opening so parts don't fall into it.

3. If you have a lever handle with a red and blue hot/cold button, pry it off to expose the set screw. Loosen the set screw with an Allen wrench and remove the handle. If you have a knob handle, pry off the handle button, remove the screw and lift off the handle.

4. Unscrew the cap counterclockwise and lift off. If the cap is too difficult to unscrew by hand, loosen the gray or white adjusting ring in the cap and try again. If it is still too difficult to remove by hand, place a crescent wrench at the top of it and turn counterclockwise. To avoid damaging the faucet finish, you may want to place a jar opener gripper between the cap and wrench or a heavy cloth such as a towel between the cap and wrench.
   
   CAUTION: IF YOU NOTICE THE CAM TURNING ALSO, QUIT TURNING IMMEDIATELY AND CALL A PLUMBER.

5. Remove cam, packing and ball by lifting up on ball stem.

6. Place replacement packing and cam over stem of ball and engage tab on cam with slot in body. Push down.

7. Partially unscrew adjusting ring and then place cap over ball stem and hand tighten onto body, while pushing down on cam to keep cam's tab engaged with slot in body.

8. Tighten the adjusting ring until no water leaks around the stem when the faucet is in the full on hot and cold mixed position and pressure is exerted down on the handle.

9. Loosening and tightening the adjusting ring also controls how hard or easy the handle is to use. Over tightening of the adjusting ring can cause premature wear of the seal surfaces necessitating frequent repairs.

Most likely, you are experiencing "shower-rise" where the water can’t get out of the spout as fast as it flows through the valve. This causes the water to back up and come out the shower head. There can be one of several reasons for this:

1. The valve could be upside down
2. The length from the valve to the tub spout is outside of the 8" to 18" rule
3. There is more than one 90-degree angle
4. Something other than copper or galvanized pipe was used going to the spout
5. The most common reason is that there is something restricting the water flow to the spout, e.g. solder or something lodged in the pipe. Something is impeding the flow of water to the spout and causing it to back up and go out the shower head. If this is the cause of shower-rise it is possible to remove the blockage by removing the tub spout; then, feeding a plumber’s snake or a speedometer cable up through the tub drop. The act of feeding it causes it to twirl and loosen the blockage. Be sure to flush the valve before reinstalling the tub spout. Be sure to check the tub spout itself for blockage.
