Hello,

I'm shopping for a couple new tub/shower faucets, as we have the old two handle faucets in both bathrooms and both sets are pretty well shot. I was looking at Delta, and just trying to get more information on what pressure balanced vs thermostatic (Delta's TempAssure) valves are, since they are both available as single handle faucets (a volume control and a temp control, both on a single faucet)

We have 4 kids, so the risk of a toilet flushed while showering in the morning is reasonable - which is what I understand the pressure balancing valve will prevent scalding. What's the thermostatic valve do? Is it worth the extra money?


Here's one for example:

They are both pressure balanced..

The difference is preference.. Some like seperate volume and temp controls..

But...

When I tell the customers that their fancy thermostatic faucet will be $400 bucks or more to replace the cartridge they cringe.. ( sometimes cry) lol..

Carts in that variety run almost $200..

I would stay with the standard faucet... Im also partial to Moen... Moentrols.. I dislike the posi temps due to cost also......

 

Example.. ( Make sure it has the 1225 B cartridge) The home store stuff seems to sell knock offs with a different cartridge..

But doesn't Delta offer lifetime warranty on parts and finishes? And why is the valve body so expensive for Moen?

I like the temp and volume controls. The better half likes her shower full blast, while I dial down the flow now with the two handle shower we have now. But we both like the same temp, so the idea of 'setting the temp and forget it' sounds nice. I'm not sure if I would like the push-pull style of the Moen.

I can get the trim kit I listed with pressure balanced cartridge, or with thermostatic cartridge, but I guess I don't understand what the thermostatic adds. If the hot water lowers in temp at the inlet, but pressure remains the same, does it automatically compensate to maintain the same output temp?
