What are these adjustments on this valve?


I have a Moen valve like pictured below. What are the two adjustments on either side? Are they just to limit pressure or flow? If so, I like full pressure, should I open both all the way?

Thanks!

shut off valves, so you can take it apart if needed without turning off the building. make sure they're all the way open so there isn't a flow restriction

Ok, that's a nice feature. I tried turning them but they kept going, I didn't know if they would eventually bottom out or if they would just keep coming out until they fell out. I'll try untwisting them all the way like you said.

On another note, does this valve limit the water flow? Originally I thought valves like this with just temperature adjustment allowed the full flow of water thru them. but now that I am doing some reading, it seems as if they might limit the flow quite a bit Is that true? I was happy with my old 3 knob diverter design, I hope this newer valve isn't going to yield a worse shower.

it will limit flow compared to your old valve, but so will the showerhead. most showerheads will only allow 2-3 gpm, the valve will easily deliver twice that

I was planning on using my old unrestricted showerhead.

I am not positive, the valve and paperwork are at my house where the work is being done. It's a Moen Posi-temp single adjustment and it looks just like the picture above.

from what I can find, this valve only allows 2.5 gpm to the shower head.

as to the stops or shut offs. If you will look at this pdf, http://www.faucetdirect.com/mediabas...ns/62370pt.pdf and look at the exploded diagram of your style of valve, you will see that the valve is a cylinder with a through port. I can't tell the relation of the slot in the stem to the port in the cylinder. Often times, they are parallel. You can try it in both the vertical and horizontal positions. One would be fully open, the other fully closed.

Can I ask where you found that? I haven't seen any info regarding flow limit from this type of valve.

Tomorrow when i find the exact vale model number I would like to compare, thanks.

I see, but I'm pretty sure those specs are for the shower head.

You're probably right. As I read more, I also found a 1.75 gpm listed and the only thing different seemed to be the head. Given the rules and the changes, it wouldn't surprise me to see it incorporated into the valve though. Hopefully not. I can always turn the shower down but there are times when a high flow shower is required.

I've found bits and pieces of info, something said that the Posi Temp was capable of 6.3 gpm which isn't too bad. I still don't know why they have to restrict it at all.

well, in reality, there are a lot of areas of the country that are starting to literally run out of water. It is something that is going to get a lot worse.

You just borrow the use of water, you don't consume it. The water I take out of the ground in the back of my house to shower with goes right back in the ground about 120 foot away in the front of my house

Even if you are on city water and sewage, you buy the water and then you pay for them to take it after it's soiled, treat it, then put it right back to be naturally filtered and used again.
