My daughter's kitchen faucet is a two piece Price-Fister pullout model (don't have the model no.) with separate spout and valve body assemblies. The flexible output line that runs from the valve body to the spout has a plastic fitting at the valve body between the two inlet lines to the valve. Pretty tight quarters in there.While replacing a dripping cracked supply valve (hot) at the wall to the faucet valve, I decided to check all the basically hand tight fittings that I could see. The above mentioned fitting at the output from the valve appeared very loose. In fact I could turn it w/o any effort at all and actually twist the ouput line. Because of this I assume it is a QD type fitting. Am I correct? How prone are they to leaking? It would only see supply line pressure when the faucet is turned on.
Though I don't do service work every day, I have yet to see one of these leak. Without looking at it I couldn't say for certain that it is a quick disconnect, but that is the common fitting for that application.
Update: Got a chance to take a closer look at that fitting. Pulled the control valve up through the clearance hole in the sink and was able to see that it is a Parker Parflex plastic QD attached to the flex pullout hose. The other end of the fitting looked like slip fit to a 3/8 copper tube (approx 4 inches long) that screws into the control valve. The occasional leak appears to be at the fitting/tube interface. The p/n? on the qd fitting is (I think?) NSF-51761 Size-6. The 6 jives with a 3/8 tubing designation. That is the only marking that I could find. After researching on line I found that I could've disengaged the fitting from the copper tubing by pushing the "collet"? and the fitting body together and the pulling them away from the tube. I had unscrewed the hose from the fitting and then the fitting and tubing from the valve body. The Price-Fister Model No. looks like 526 series Contempra. The leak appears to be sporadic. Didn't leak for several days. Then today my daughter heard it drip but only for awhile after the valve was shut off. My thinking is that maybe the jostling of the pullout hose moves the plastic fitting sideways and cocks the o-ring inside the qd. Then the water in the pullout hose that is above the fitting (both in the spout and valve end) leaks out until the level is below the fitting. The small amount that was in the plastic container that we placed undernearh jives with volume of the hose above the fitting.
Questions: Can I get that fitting at a plumbing supply place? Can I get just the o-ring? I don't particularly want to buy the whole pullout hose.
QD(quick disconnect) fitting?
