The hole under the seal and spring for the cold side is plugged with dirt....
a small screw driver will sometimes do the trick, and sometimes you need to unhook the piping underneath and blow air back through it...

    Thanks Heatman - I cleaned the flow hole when I replaced the seat and spring. I did so again, at your suggestion (obviously, I could not go too deep as there is a 90 degree elbow about 4 inches in). Put eveything together - no change. So, I removed all of the faucet hardware and compared the flow of hot and cold separately, using just the shut-off valves and checking the flow through the "raw" holes. The flow is equal, so I assume there is no pipe blockage. The pushbutton diverter is broken (has been since we bought the house) and the previous owners simply replaced the nozzle (simple pull-up) rather than replace the pushbutton. I am going to remove the pushbutton and insert a plug. I am now thinking that the pushbutton diverter is affecting the cold water flow. I'll let you know what happens. Thanks again for your input - I really appreciate it. Cheers. Joe - State College PA.

Why shower head drip when faucet is open half way to mix cold with hot

If its single handle you have a bad ball valve or seals they make kits to replace the ball assembly for single lever showers....... you will need to have the water off for an hour or so to fix this...... shut water off at street or inside the house then remove the handle to shower if acrylic you remove the cap in middle of handle then remove screw then handle comes off once you do that there is usually a crown nut ( chrome doam ) that holds the stem into the body of shower manifold...... take a chanel lock or vice grip put cloth around it to keep from scratching and turn in counter clockwise direction once you remove the crown then the assembly will come out you may have to gerk it by attaching vice grip to stem ( btw always put cloth over drain to prevent you from losing that its out you have to go to big box store and match up a new ball assembly with seals and spring ( be sure to note if it is moen or whatever but i always take assembly and go .... they sell two kits one a seal and spring replacement and two seal spring and new ball go home take the old seal and spring out feel around with your finger to be sure all is smooth and put new ball in ( these are keyed meaning there is a notch to match up ) make sure ball and collar seats before you put the crown back on and there ya go! good luck

Can't regulate a delta shower.

If you have the type that you turn the handle like a clock, you have to find that perfect spot. It can be 3/4 of the way around. If you have the ball type, single lever, the rubber seats and springs under the ball should be replaced. Cost...less than $10 for the kit to do yourself.

A metal ball controls the temperature and flow of water from the spout in the vast majority of Delta single-lever faucets. That ball rests on three rubber seals, each seal suspending the ball with a single spring. Over time, wear on the seals, the springs and even the ball itself typically results in leaks. Thankfully, repairing the faucet is relatively simple, and Delta even makes repair kits with the replacement parts needed for each model.

Turn off the valve that controls the main water supply. The valve is located next to the water meter, inside or outside the house, and must be twisted in a clockwise direction.

Remove the plastic cap from the center of the faucet's handle by prying the cap free with the blade of a dull knife or a flat-head screwdriver, then remove the screw in the center of the faucet handle with a Phillips-head screwdriver. Pull the handle off the faucet assembly to remove it

  • Remove the single bonnet nut that surrounds the faucet valve with an adjustable wrench. Grip the bonnet nut at the base, which is ribbed to give the wrench a surface to grasp, and turn in a counterclockwise direction to remove it.

  • Remove the circular, white plastic cam that surrounds the top of the faucet, pulling it off and revealing a rubber seal, which you also remove. Next, pull the metal ball out of the faucet assembly and pry out the ball's supporting rubber seals and their springs with a screwdriver (the springs slide onto the bottom of each seal, so they will come out along with the seals).

  • Slide one replacement spring onto each of the three replacement seals that come with the Delta repair kit for your faucet model, then insert each seal into the assembly. Insert the replacement ball from the repair kit, then cap it by putting the replacement rubber seal over the ball, followed by the plastic cam

  • Place the bonnet nut over the faucet valve, then tighten the nut with an adjustable wrench. Position the handle onto the end of the faucet, then insert a screw into the center of the handle, tighten it with a Phillips-head screwdriver and, finally, press the decorative plastic cap over the screw.

  • Turn on the valve that controls the main water supply by twisting the valve in a counterclockwise direction to complete the repair

    Replaced my Moen cartridge, finally got the leaking to stop, but now have no hot water no matter which direction the single handle is positioned

    Turn on hot water supply

    ok to easy but maybe

    take valve cartridge out of valve It may be put in 180 degrees out

    compare cold side inlet to warm side inlet: spring, little black gaskit/s seal maybe a ball/s

    The cold side works right

    Take out the little plastic hot and cold water symbol from the handle and you should find a set screw in which you can remove to get the handle of for access to the main insert and seal...Hope this helps.

    Attempted to update a single level "diamond" ball shower handle for an older Delta 600 series. Everthing seemed to go well, but when I turned the water supply back on, and when the handle was pointed...

    On a single lever shower handle, when the handle is pointing straight down the water is off. The handle will then rotate 270 degrees to the right through cold - warm - hot. What has happened is when you took the other handle off the new handle didn't go into the same position as the old one. So now when the handle stops at the down position the valve is still open probable running cold water. The fix is to take the handle back off. Rotate the valve into the off position so that water stops flowing and reinstall the handle pointing down. Now when you rotate the handle to the right you will get cold then warm then hot at 270 degrees and back to off when the handle is pointing back straight down. If you are still having problems please let me know and we will examine it a little closer.

    I have an older single handle Delta shower valve, and I am only able to get good water pressure on cold water (which is opposite of the normal right hand). Can you suggest a solution?

    A rebuild kit for a shower is pretty cheap for delta. the actual ball behind the handle maybe wore and not allowing it to seat properly and restricing water flow hot side.

    Also if you take it appart the 2 washers and springs you might as well replace them also.

    Replace washers and springs and the ball with shaft that handle fits to.

    Shut off water before taking appart.

    Delta Series 1400 shower faucet, no or very little water out of the cold side of the faucet. Plenty of hot water. What can I do to fix this?

    Remove the handle by opening the little red/blue cap. Use a hex key to remove the handle. Remove the tope ring holding in the cartridge in. Take out the cartridge and you will most likely see particles blocking it. make sure you use a little valve lube or vasline on the seals before you put it back in so you will have smooth operation. If that doesnt cure it just replace the cartridge at lowes or home depot and bring the old one.
