New member, mixing valve question.
 
Hello everyone, i'm new here, i've been lurking and finally have a question of my own!

My mixing valve broke in the 'off' position last week. It was one of the kinds without volume control, so it was always full pressure, and it looked like it was older...not sure. I removed the restricters out of my shower head and shower neck and the pressure was insanely high on my shower, it rocked...until it broke.

A few days ago we bought an American Standard kit with volume control that was like $70 from home depot, but JUST installed the mixing valve+trim+handle, we didn't mess with the tub faucet or shower head/neck yet. After getting it hooked-up, the pressure was SIGNIFICANTLY lower, it sucks taking a shower now. I read the directions and it doesn't have adjustment screws for the anti-scalding feature, jsut a stop ring you adjust, so that doesn't effect the pressure at all.

Can anyone reccomend a brand that has good flow through the mixing valve? I would prefer to get one with a volume control handle, but if all of those are lower pressure than non volume control ones, I can go that route. Thanks again

What mixing valve are you referring to?? Shower faucet?? On an anti -scald constant volume faucet, the ring is the only adjustment and that is for max temp. If the volume is low, make sure all shutoffs are full open. And remove the cartridge and check for debris clogging one side. If one side is clogged, the other side will automatically have low flow, that is how they work.

I'm referring to a 1-piece mixing valve, the one I installed controls both the flow and the temp, I have a tub/shower setup. What do you mean by "shutoffs are full open" ? Do all mixing valves have these shutoff things? How can I adjust them? I don't see any reference in the instructions. Also this is a brand new valve so I doubt there's any debris in it, my old one I removed was even pretty clean.

Thanks for the reccomendation! Can you give me anymore info on this? Is this a known good mixing valve setup that provides high pressure? Is it easily adjustable for min/max pressure or something? Any additional info would be great, especially from a licensed plumber.
