Kitchen Faucet Lower Pressure After Construction

cbut8995 | Posted in General Questions on

Redid our whole kitchen in a condo we just purchased and have the following installed that are connected to the kitchen water valves (faucet, d/w, water supply for fridges (water and ice). The original built had GREAT water pressure for washing dishes and it used a really old model of faucet 

However after the reno, we kept the same amount of things using the kitchen water supply but now have a bit better appliances, sub zero fridge with water dispenser and ice maker, bosch dishwasher, and hansgrohe faucet.

The faucet is SUCH low water pressure and I also removed the restrictor in the nozzle. It was a bit better but is still lacking to what I am used to. 

Any suggestions?

    Did the plumber change the supply lines? If not, gotta be the faucet.

    You should check if your faucet has more than one flow restrictor. Some faucets have two restrictors, one in the nozzle and another back in the supply line part. Make sure you got both if yours has both. I would also check that the supply valves serving that faucet are fully open.

    If the faucet has a pull-out sprayer there will be a backflow preventer. Those often restrict the flow.

    I drilled out the restrictor in my Grohe faucet. Don't tell anyone, but it fixed the flow issue.

      I drilled out the restrictor in my rain shower head. It was more like a drizzle before I did.
      Don't tell anyone.
