 Simple question - bathtub hot/cold cartridges
Author: broton (NY)

So I just replaced the two faucet "knob" cartridges for both the hot and the cold valves. It was a real pain in the butt... old knobs, hard to get off, etc. Any who... guess what? I'm done. Except I realize that I put the HOT one in the cold side, and the COLD one in the HOT side. Does it really matter? Beyond the direction you turn the knob to let the water flow? I don't think so... but am not sure. So I ask you fine folk.

I can understand you'd need to label the packages somehow so you know which direction each cartridges turns, and I assume just calling one HOT and the other COLD makes sense, or is easy. The only other reason I could see is if a gasket inside each is made specifically to handle HOT or COLD water. But I think that's overthinking this...

Help! and thank you.

other than the direction the turn on/off, there is no difference.
a little grease on the end of the stem will keep the handles from sticking so badly next time.

Z,
Traditionally, all hot water stems on spread ( seperate hot & cold valves / handles) faucets open counter clockwise and close clockwise - that includes round, cross ( like a t or x ), or blade ( aka lever or wing ) handles.
Cold valves / stems that have handles that are round or cross, should open counter clockwise and close clockwise just like all hot faucets, however, cold faucets with blade or wing handles should open clockwise and close counter clockwise - for instance, on a faucet set with wing or blade handles both hot and cold will turn towards the spout to open, and away from the spout to close...........

That is true for "main line" faucets, but NOT necessarily so for "specialty" lines such as Santec, etc. They usually send ALL faucets with stems for lever faucets, regardless of whether you also purchase "round handles" or not. Sometimes changing a stem from hot to cold, or vice versa, is simply a matter or rotating the stem, cartridge, or clip.
