Question about Delta & Single Handle Shower Faucet

Open Question

Repair Delta Scald Guard tub/shower faucet. Not your simple mixing valve fix. I have freed up and tested both hot and cold shut off valves and the mixing valve with springs and cups. I get full flow of hot water but no flow of cold water. This has a scald guard device between the cold water shut off and the mixing valve and it is probably stuck form many years of no use. It has a brass plug with an oblong slotted shape that probably needs a special tool to remove. It won't come off with just a large screwdriver. Is there a special tool for this?

SOURCE: MY DELTA SCALD GUARD FAUCET WILL NOT TURN OFF HOW

When a Delta Scald Guard will not turn off, more than likely it is because the seats have worn out. Turn off the water supply and open any faucets lower stream of the shower unit. Using an allen key, locate the set c=screw in the handle and back it out. Next,Remove the Phillips screw holding the handle in place.Next turn the retaining ring counter clockwise and pull the catridge out of the faucet.Some catridges have two parts front and back. Behind the back part id two small rubber washers called seats and two springs. Install two new seats and springs and everything else in reverse order.

Not hot water should not exceed 120 degrees. If it does it will continue to melt the seats.

Can't get both hot water running at the same time. Delta Shower faucet


  • 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.

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.

The hot and cold are reversed on our single handle shower (no tub faucet -- shower only)


Hot on left.
Cold on right.
Some single handle faucets have bleed-over where both hot and cold enter mixing valve each time handle is turned on, even when faucet calls for just cold or just hot.
Otherwise maybe a do-it-yourself plumber got pipes backwards... or maybe the tub used to be on other side of wall, and tub was moved during remodeling but pipes were not changed.

To fix problem:
First of all, turn off shower faucet. Turn on Hot at sink and put ear against shower faucet listening for sound of water flowing through the mixing valve.
If mixing valve is working fine, you need to open wall and investigate more.
For example if you have access door, reach in and feel which pipe is hot.
Pipes might need to be reversed if problem comes up in home inspection, otherwise the problem will not harm anything.

I have a one handle shower/tub faucet, and when you run straight hot water (to preheat for example) the water shuts itself off. Lever is still in the lifted/on position however. Cold is fine, even warm...


If this is a newer valve what is probably happening is the valve is a scald guard valve and is shuting itself off when it senses no pressure on the cold side. I don't have a lot of experience with am. std. valves but I'm sure you can get instruction on line to set heat setting on valve higher. Thank you.

Pull apart the front of the valve and there is a limiter that is set to limit hte hot water, you need to adjust that limiter. I find many valves are shipped with teh setting too cold.

I have a older Delta shower head/tub combination with scald protection. It leaks from the tub diverter. Where should I start?


I'm assuming that you have a three handle faucet. You need to remove the diverter from the faucet body and while your at it remove the hot and cold stems from the valve body (the parts are inexpensive). Remove the seats inside of the valve body towards the back, replace with new ones. If stems are in good shape, just the washers and seats need to be replaces. If the brass on the diverter or on the hot or cold stems is pitted or marred, then replace the whole thing. The parts should be readily available at most plumbing supply places.
