Weak body spray with 3/4" lines

I have 2 Delta 1G/Min Body Sprayers which 3/4" lines but the sprayers feel weak to me. I know it is subject but it just feels like it should be stronger. Is there any benefit to removing the restricter/o-ring?

Did you pipe it with CPVC or Copper? Not sure, but check the instructions, as it may require copper for Delta. They claim too much friction in CPVC, for what that is worth.

Was the 3/4" installed as a pressure balancing loop working during the rough-in? It would be an actual complete loop of the 3/4" line and the body sprays branch off the loop.

And is it 3/4" all the way back to the main lines?

City water or well? Do you know what your water pressure is? 3/4 lines or not, if your pressure is low you won't get the rated volume/intensity.

Copper. 3/4 all the way to the main lines. City water. Not sure the pressure but we have a 'restricter' in place.

I guess it can't hurt to try as it appears I just need to use an allen key to take the head off the sprayer.

Here is a link to a pressure balance loop for spray heads. You never answered if these are present. Without them, you will get a dribble out the furthest spray head as the closest ones will bleed off all the pressure.

Also, could you post some pics of the shower set up. What master rough in valve body do you have? Is it a higher flow model? What type of transfer valve do you have installed? 3 or 6 function? Or provide a schematic of how the shower was roughed in and pipes run.

My apologies as I missed the pressure balance loop question. Yes, I had a pressure balance loop installed. Below is a list of relevant items and I attached 2 pictures but couldn't find a good picture of the roughings.

Check that the shut off valves on the main body are fully opened. If they are not, it will slow the flow down. I have always used multi-function diverters to change the flow of water to the various shower heads. You have on/off valves which I am unsure as to how they change the water pressure or flow. Does each unit have a direct flow off the main valve or do the spray heads pass through more than one valve before the water gets there?

How can i check that? Would I remove the allen key to remove the trim piece to see the main body? I am not sure to your other questions. Is it a bad idea to remove the trim and remove the restricor/oring and see if there is a difference? My only concern is that it somehow leaks in the wall.

Remove the main supply trim by removing the handle and unscrewing the two retaining screws. Behind the trim will be the valve body which is connected to your water supply lines. On the valve body will be two shut off screws. This would allow you to turn the water off to change out the cartridge. Clockwise to close the valves, counter clockwise to open. Make sure they are fully open.

Here is what you should find:

Use a screw driver to adjust the center portion of the valve with the slot in it. Do not use a box wrench on the hex nut surrounding the center screw slot or you will flood the bath.

My other question had to do with the routing of the pipes after this valve. I can not tell from your picture the complete rough in set up.

My apologies for the delays.

I am not sure I will have the room to adjust those two nuts even after removing the handle. Is this as straight forward as removing the handle/trim and using a flat head to loosen (counter clock wise) the center screw within the hex? How 'open' does it have to be? Will it stop turning?

If this doesn't make a difference should I consider removing the limiter?

To be clear, you are making sure I use a flat head on the center screw slot rather than turning the hex nut in any way, correct?

Use a screw driver to adjust the center portion of the valve with the slot in it. Do not use a box wrench on the hex nut surrounding the center screw slot or you will flood the bath.

You have a slightly different handle on your unit but this video explains how to get to the valve for you to adjust the pressure. Valve adjustments are toward the end of the video.

Any particular reason why you haven't mentioned the oring?

And to what o-ring are you referring?

Sorry. I was on holiday for a bit.

I used the term "oring" to describe the flow resistor that is usually installed within shower heads.

Well, the flow restrictors have a tendency to increase pressure, if you removed them you would see more volume possibly, but less pressure or force behind. Would lead to weak body sprays. Think of it as if you took your garden hose and pinched off the end with your thumb. You may get less volume, but what does come out is at higher velocity and higher pressure.
