    Question Thumpin pipes

    We just moved in to our wonderful 1927 Foursquare and of all the issues I have found, this one is by far the most vocal is this thundering thumping the hot water pipe @ the kitchen sinkdoes.I have read discriptions of hammering; I dont believe that tis is it, but will let you experts diagnose for me.
    First off the sink is orginal with 3 faucet handles.I ahve included a pic. Not sure what the third one is for, it is under the other two in the middle. This thumping starts after the hot water is turned and and gets hot, it will sputter water even and scream and squeel, then as you turn the handle back, it may or may not stop.Off is off though and does not make any noise once the valve is closed.
    The young man at Lowe's suggested I screw off the cap at the end of the spigot clean out the screen(no screen)then turn off the valve below the sink, drain the water from the line then turn the water back on. I did this yesterday, I dont believe I saw much, if any of a change.
    This is the only place it happens, not in bathroom or down in the basement, just at the kitchen sink.
    Thanks for looking.

    That third valve looks like it was for a hose spray at one time, that has been caped. That is more then likely your source of the thumping.

    Okay, can you purchace a sprayer for a faucet that old? My husband would like to upgrade the sink, faucet and all, but I rather like it.

    It's possible that third faucet could be to a spray hose somewhere, but then there should also be a visible cap either at the faucet or near the sink in the wall. That cap will likely be a standard garden hose thread, hard to say with such old devices, particularly if they've been abandoned. If this is the source of the hum/hammer, then you can test this theory by giving that third handle a twist and see if the sound changes or goes away. If this happens, then it's time to replace the seat washer, which is either very warn, disintegrating, or loose.

    That third valve could also be a "fixed" temperature valve. The hot/cold would be set to the desired temp, then the third valve would turn the water on/off without changing the temp. Makes for easy one handed control.
    I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!

    I don't think it's a temperature valve, there is a third opening that go's back through the sink. That could be a problem as far as replacing it.

    I am going to post another pic ,perhaps this will help show excatly how the faucet is constructed.

    I have tried twisting that third handle,I think sometimes it helps or that may just be my imagination..lol for sure there is no where to set a sprayer down, and you are correct, there seems to appear three distinct holes.

    Where would this seat washer be located? My husband was thinking it could be in the hot water valve on the faucet.

    Crawling under the sink and looking up behind it, there is what looks like a pipe coming out of the back of the sink, but it is solid not an open pipe.
