It’s the lines going to the faucet , we tightened the clamp d but it’s still leaking from somewhere, bit you can’t get under there to see you have to feel for it and there’s no way to remove anything unless you cut the sink outWhat is leaking? The underside or the top side? does it leak all the time or only when used. Most likely, if it is leaking from underneath and you can't see what actually is leaking, you may need to remove it and inspect
We tightened the clamps , but I guess we ca try and pull them off and inspect themI would think it's a loose/stripped hose clamp (most likely) or hose deterioration/cut. Can you loosen the clamp enough to pull of the hoses off at sink fixture connection and inspect/replace?
Yes maybe I can try that to see where it’s leaking tyCan you stick your phone under there and take pictures?
