Delta shower valve - cold water limited?

6 years ago

Recently renovated master bath and installed the Delta Cassidy line. We put this thermostatic setup in the shower. Yesterday after hot yard work, I wanted a cold shower. But no matter how far I turned the handle toward cold and waited, the water would not run cold. I couldn't even get it tepidly warm. Everything is tiled in with no rear access to the valve. Our water heater is set high, so SOME cold water is getting mixed in. But not much. Can this be adjusted by removing the valve trim only? My contractor thinks it can, but I am worried. And if it can, will this limit how much HOT water we can get? I guess he will send the plumber. Again. This job has been dogged by bad plumbing. This will be their seventeenth trip to repair, redo, or replace stuff. Including my downstairs ceiling, which was pristine when the job began. Anyhoo, appreciate any guidance.

All I can add is that the two Delta kitchen faucets I have had were terrible at mixing hot and cold water. There is one tiny space where I can get warm water. Any other place is all hot or all cold. I wouldn't buy Delta again. I wish you luck. The stress is why I am not redoing anything in my house.

I recently installed a Delta single handle shower control, and the max setting for hot was accessible after removing the shower control trim. The piece that determines the max hot water position is is just two sets of toothed/geared wheels that fit together, and you can index them in either direction.

This youtube video provides a good explanation of the hot setting for the Delta single handle controls. https://www.youtube.com/watch?v=n2_uZ7wgV1I My shower valve worked like the one shown at about 2:07 minutes into the video.

Tankless water heater - one shower got cold
Q
Comments (41)
Ok, so I've read through most of the posts here but was unable to locate my problem. Just had an ECO Smart ECO27 electric tankless installed 2 days ago in the lower level of my tri-level, which is where the previous hot water tank was located. Every faucet except the upstairs bath tub produces hot water. When the upstairs tub tap is turned on the output pipe from the tankless unit goes cold. I tried running hot water in the kitchen, which it was hot, then turned on the upstairs tub tap and the water cooled off. Any help provided would be greatly appreciated.

no hot water from new shower valve -- what am I missing?
Q
Comments (1)
Some basic troubleshooting. I slid the rotational limit stop out of the way so I could open the valve fully. Even when fully open, not obstructed by the limit, I got no hot water. The inlet pipe coming in from the right side of the valve feels cold, so now I'm back to the opinion that the cartridge was installed upside down. So is that a reason why no hot water could be getting mixed into the valve?

Can’t control shower hot water volume Delta faucet
Q
Comments (6)
Maybe there could be debris, and I could have the plumber come back next week if the pressure won’t go back up. However, I’d stil like to know if there is any method to vary the pressure on the hot water side so it isn’t just full pressure or nothing. I’d like to be able to adjust the water volume on the fly and maybe use more pressure when I turn on the hand held attachment to wash out the shower and spray away Bon Ami residue from the tile than I would use for actually showering. I neither want to shower under a power washer nor have such low water pressure that it can barely rinse the soap off.

Delta Monitor Pressure Balanced vs Temp Assure Thermostatic valves?
Q
Comments (12)
Yes, if the pressure balanced valve senses a drop in the cold water supply pressure, an internal valve moves to cut down the pressure of the hot water as well. Thus, the flow from both hot and cold are momentarily reduced together and the outgoing temp remains fairly constant. If the hot water pressure would suddenly drop, the opposite would occur. This balanced valve operation is quick, in a fraction of a second, and fairly inexpensive to implement. The thermostatic valve adjusts the outgoing water temperature via a slower changing sensing mechanism. Any change in water temperature has to soak into/out of the wax element in your drawing (it is likely inside a brass housing as well), so it takes many seconds for the heat to soak into/out of this element and effect a change in the balance of hot and cold water. This is much too slow a process to protect one from scalding from the flushing of a nearby toilet; with only a thermostatic valve present, the drop in cold water pressure & flow could cause a scalding event to occur. This thermostatic design is also a fair bit more expensive to produce which is why far fewer homeowners have them installed.

Easily. Just as Bruce described. The plumbing subcontractor finally sent a good plumber, and he popped the valve trim off and fixed it in 30 seconds. Unfortunately, we have since sold the house and moved. absolutely loved the Delta Cassidy plumbing. Once the temperature was set, it was beautiful and amazing.
