American Standard Cadet 2-handle tub & shower set-Model#3275 - low pressure output

Be sure to pull the plunger all the way up when diverting the water between the the tub and shower if ti keeps giving you a problem it's faulty

I think fitting of your shower is not proper. You have to fit it properly if you can or you can call a nearest Plumber to solve your problem.

sounds like one of the stems are leaking thru.

These types faucets have a what is called an anti scald valve build into them, it is required by law, it is either defective or out of adjustment, contact a local hardware store for more detailed info.

That is normal with that faucet.

If this is a newer valve what is probably happening is the valve is a scald guard valve and is shuting itself off when it senses no pressure on the cold side. I don't have a lot of experience with am. std. valves but I'm sure you can get instruction on line to set heat setting on valve higher. Thank you.

I just spent a week wrestling with a similar problem, and I'm posting in an attempt to save someone else an ulcer. Using a Colony single-handle valve, the temperature got so we couldn't control it. Either all hot or all cold. I called A.S. and they sent a new pressure balancing cartridge and new valve cartridge. Replaced both and then there was no water at all coming out of the shower head. Tried every possible combination of old and new parts, flushed pipes, etc. Finally took the shower head off and found it completely clogged with debris. It was a mix of sediment and the white grease that was in the new cartridges, which must have been displaced when I started messing with it. And it clogged it all at once (no flow problems before all of this). Works fine now!

You may have debris caught in the cartridge. I'm not sure which faucet you have but if it utilizes a ball, there is a retaining ring that is either grey or white that you have to tighten. If not, I would recommend contacting American Standard. You might have a bad cartridge or missed replacing another part. Sometimes they have small round washers at the back of the housing that need to be replaced as well.

Yes, there is a non-replaceable plastic restrictor device screwed into the tub spout outlet of the faucet body. It's purpose is to force the flow down to the spout for when the spout diverter is not closed. It keep water from rcoming out of the shower head when the tub spout is also discharging.

This is all fine and dandy where the water supply is clean without sediment. A co-worker of mine had one of these and old galvanized piping. After 3 years, it clogged up. She got a 'deal' from a handyman plumber to replace with an identical faucet. She will have the problem again. If she had spent the money to fix it right, she would have had a single handle mixing valve put in. If it clogs, you can just pull the cartidge from the body, clean it and put it back in. Now she will have to cut into the wall again, get the plumber to replace the 2 handled unit and patch the wall again.

Or, she could have the plumber drill out/remove the restrictor but then she might get water out of both outlets at the same time....."pay me know or pay me later"....repalcing the mixing valve with a scald prevention single handle valve (with remodel plate) is the BEST long term solution.

All you should need to do is remove the shower head and make sure that their isnt any dirt obstructing the opening ,also if their is a restrictor like you said you need to remove it.This should make a big difference.
