    I bought A new shower head, and it has hardly any pressure at all. I looked at my old one, and it looks like the water supply hole..is much larger, than this new one. Has a smaller diameter. Do they make different sizes.? I been retired a long time now. Am i missing something here// any help i am grateful bob s

    Since about 1987, Federal regulations have restricted water use in various devices you can buy. Prior to that, they were pretty much unrestricted, so yes, if you have an old one, it probably has a larger inlet and, if you have an older supply valve, that may have a larger port to it as well.

    Today, it's illegal to sell and in most places install a device that does not meet those guidelines. This applies to showerheads, vanity faucets, kitchen faucets, toilets, urinals, and most things.

    On some devices, you can defeat that by just removing a restrictor, on many, you'd need to drill out the hole. You really shouldn't, but it's your house. Larger volume not only means more water used, but more energy used to heat it, and more water that needs to be run through the sewer system. Michigan may not have an issue with water, at least if you're near one of the lakes, but still...as a country, it matters.

    FWIW, the pressure is identical, but the volume is down, probably considerably. It's a function of how many and how big the spray holes are as to the 'effective' pressure you feel just like a soda straw verses a fire hose, both being fed from the same supply...one will have LOTS more volume than the other.

    Not all showerheads are created equal...there are actually some that work quite well and still abide by the restrictions.

    CLR, or just plain white vinegar can dissolve mineral deposits...CLR is probably better at cleaning rust, if it's that.

    WAS SETTING HERE THINKING ABOUT Showerheads.If i had kept those i bought and returned. Theres no way yo can warm up a shower first, especially in winter, And lets just say..a 300lb man or woman taking a shower in mandated 2.5 gal pm. Would be dry in some places and wet in others. It might become a battle to take a shower . man i am glad i got my old ones rebuilt bob s PS; All the rules laid down in what plumbing appliances are supposed to do,aren't always going to be the "rule of thumb"for everybody.

    What you CAN do verses what you MAY do are not always the same. I picked up one of my cars in Germany, and while I know I CAN drive it at 100mph and faster on a highway, at least in the USA, I MAY not do it. Course, whether you'd ever get caught or not, is something you have to consider. Just trying to make sure people understand what they MAY do and not have ramifications with the inspector.

    Bob,
    Yeah, it's the nanny state looking out for you.
    Grrr
    If you still have the old head try soaking it in vinegar for a couple of days to remove deposits.
    Orherwise, look at the inlet in the new head. Sometimes you can simply remove the flow restrictor. Or worst case, drill it out.
