Well damn, it's the case of different regulations for different areas..... here, they only install back flow preventors for new commercial buildings.

It is due to meth labs. The cities want to protect the water supply from any contamination.

I have MOEMs in the showers...they give free replacements. I get two every two years so I don't run into any of them sticking into the unit.


Don't. drink & drive, don't even putt.

My Delta kitchen faucet cartridge lasted less than a year.
They are all made like crap now unless you pay many hundreds of dollars for a all steel/brass unit.
I used to photograph the Chicago Faucet catalogues years back, they were made like tanks but the price tags reflected the high cost. I wish I had stock piled some of those when I had the chance.

Delta will send free parts for anything you have of theirs. I’ve replaced a lot of cartridges over the years for drips. They never question it. They even sent me a new handle when the one I had stripped out.

That said, expansion tank and softener help. I’m on city water, but soften to prevent water spots and calcium build up in your system. May also check your expansion tank if you have one. They may be required by code, but I’ve met several “plumbers” that didn’t know how to set the pressure properly. It’s odd that your adjustability goes unless one side is plugging up in the cartridge somehow?

Funny, I thought they were valves. At least they were when I was kid. So I wondered if there was a difference. It led me to this

This, ask for several so you'll have a spare. Phister will do the same. That said, I've gone to all Kohler fixtures. Quite a bit more expensive but they are built like a tank.

Guess I will test the water pressure and shoot Delta an email and see if they’ll send me something. The cartridges are like $50.

Delta said they would sell me a cartridge at a discount and told me how to flush the line before putting in the cartridge.
Guess I’ll give it one more go.

I've never replaced a cartridge that I can remember, unless the handle stem or threads were boogered up. I've always just replaced the springs and seals. Delta is my go-to brand primarily for the ease of maintenance.

We just broke free from the ice, snow, and freezing temps. Plan to get a gauge and check this weekend.

About 15 years ago I converted a small bedroom, directly off our master bedroom, into a bathroom. I built-in the shower and installed a Delta shower faucet and Delta sink faucet. About 5 years in the shower temperature began to fluctuate wildly and I replaced the entire valve with another similar Delta unit. A year or two ago the valve wouldn't fully shut off, and I replaced just the cartridge.

It is common for shower faucets today to have a "scald-guard" feature, which automatically adjusts the temp down if the cold water supply gets temporarily reduced, such as a toilet being flushed on an adjacent supply line. I'm pretty sure the valve monitors pressure changes on both the hot and cold supply sides, as a means to adjust the temp adjustments. As suggested, it would be helpful to check the pressures.

In the case of our first failed valve, I assumed that something in the valve was interfering with its ability to maintain constant temp.

A few months ago the sink faucets started to drip, so I had to replace the cartridges on that as well. We are on city water, and use a water softener as well.

Good luck.
