    Cold Water Pressure
    I have no cold water pressure in my bathtub faucet. I live in an older house which seems to have been built by a couple of guys in their spare time. I don't know anything about plumbing. I read some posts water pressure but was pretty confused. Is there some kind of cartridge I have to clean? And if so, how do I do that? Please help... I have burnt my arm once already!:confused:

    What kind of pipes do you have? Galvanized or copper? What's the brand name of your valve? How old? One handle or two knobs? Happen all at once or come on slowly? Get back to me, Tom

    Hi... I tried to find out the answers to all your questions. Here's what I came up with... we have copper pipes, there are two knobs for hot and cold. The cold water comes on normally but reaches a point where if you keep turning the knob less cold water pours out. I can't figure out the brand name but the faucet is about fifteen or twenty years old. I hope that helps!

    Hi Miz Pen,

    Most stem and washer faucets are set up the same. The brand name is usually found on the face plate. It sounds like you might have something in the cold supply that moves up the supply to the seat and blocks it when you increase the flow. Let me know if you're comfortable opening up the faucet and flushing out the supply line? Cheers, Tom

    I'd certainly give it a try if you wanted to give me some instructions! Thanks,

    Miz Pen :D

    OK! Here we go. You might want to, print out the instructions and exploded drawing. Your valve might not be exactly like the one pictured but they're all built pretty much the same.

    Shut off the water to the valve and remove the right hand cold water knob and cover plate. This will bring you to the brass bonnet packing nut. Unscrew the bottom nut and put the knob back on the stem and turn the stem and washer assembly out counterclockwise. You now have a open valve.
    Check the washer and replace if it's worn or tore up. Now turn on the water for a minute to flush out the cold water supply line. You should be getting a full stream out of the open valve. If not then get back to me. Reassemble everything and test out. Better now? Cheers, Tom
