Look in the phone book yellow pages to find the number of a licensed plumber.Hi All,
We just purchased a house and I am very new to amateur plumbing. We were having an issue with our kitchen sink getting cold water but not hot. I removed the handle and cartridge and the hot water starting flowing perfectly! Unfortunately the cold water stop working and looks like is even leaking at the top of the supply hose. I am guessing there is some sediment clogging up the hose/connector but when I look for the top of the hose all I am seeing is this (pic attached) Anyone know how to get into this or where I should look next?
