I have a 2018 Durango 256RKT.
It have very low water pressure at the kitchen sink, bathroom is fine, sink, shower toilet.Is there a water restrictor in the kitchen sink tap or water connection to to it? Kitchen is at the very rear, sink at the back wall.

Ours is so low it won’t start the on-demand water heater unless you put it on spray. Spray is very heavy. It’s new enough to us that I haven’t pulled it apart, but probably this weekend. DW is ok with just the spray. May be the brand of faucet…..everything else is good.

Depending on the surface area of the valve seat (let's pretend it's 1 sq. in.), if the check valve spring is a 30lb spring, you have to adjust your pressure regulator above that to start your flow. Set at 50psi, you have about the flow of a 20psi setting, after overcoming the 30lb spring pressure. |

There is lots of pressure in the bathroom (sink, shower, toilet) |

Remove the aerator from the end of the faucet and then check the flow.

Is the issue with both hot and cold water at the kitchen sink, or just one of the two. There's a difference between low pressure and low flow. If you hold your finger over the kitchen sink faucet outlet, can you feel the pressure build to about what the other faucets pressure feels like. If you feel the pressure build, you have low flow and there is a restriction, trash, or a kink in that water line. A pressure gage, rigged up in some fashion, may help with the diagnosis.

I had same issue with my D250RES. Removed aerator to clean out small bits of plastic. Had issue with outdoor tap to as it didn’t want to turn off. Again, a small piece of plastic was caught in the valve.
