I am first time home owner facing a plumbing issue so any advice will help a lot.
Underneath my kitchen sink basin looks the photo below. Recently I was trying to adjust water pressure and all of sudden
- Hot water doesn't flow out of the connected kitchen faucet even when I fully opened the water valve
- Cold water over flow (max pressure) out of kitchen faucet even when I fully closed the water valve
- Oddly, hot water does flow into dishwasher and I can run warm (not as hot as it was before but hot enough) wash cycles.
I cannot pinpoint what is the issue here. I suppose the shut off valves are broken and needs replacement but how can hot water flow into the dishwasher? Does anyone have advice here?
