I was in the half bath this evening cutting more of the floor off and my son went and unloaded and loaded this dishwasher. When he started it, while the DW was filling, I could have sworn I heard water running under the house! Now.... we experimented with this. I had them fill the sink and listen to it while it was filling, and then I had them drain it and listen to that... and then I had them run it without stopping it up. There is definately a difference in the sounds. Now, when the water isnt running. I can FAINTLY hear a drop... but... why is it so much louder with it running... I mean I get that the harder the pressure the more the sound, but is it really that easy? I havent crawled under the house as I have to get up at 5am for work tomorrow.... and I do plan to get under there but not until Friday... and yes i am hoping that it will not break loose before then. in addition.... at what point do you just simply replumb the copper pipes... I mean... If I get this fixed, it seems to me that it will just put more pressure on other weakend areas and as damp as it is under the house. I am sure that there are lots of weakened areas. Am I wrong? for the record... I have already taught everyone in the house how to turn the water off at the meter should the need arise and I am not home!!!!
