Fix Low Flow on Kohler Bathroom Faucet
Dealing with low water flow on a Kohler widespread faucet? Learn if the restrictor can be removed and explore faucet options with removable restrictors.
Low water flow from a bathroom faucet can be frustrating. Many modern faucets, including the Kohler Sundae widespread model, use built-in restrictors to meet water-saving standards. While these devices conserve water, they can sometimes reduce performance, especially in homes with already low pressure.
Some homeowners want to remove the restrictor for better flow. But can you do that on a Kohler widespread faucet, or is replacement the only option?
Question:
Can the flow restrictor on a Kohler widespread Sundae bathroom faucet be removed, and what are the alternatives if it cannot?
Answer:
No. The restrictor on most Kohler widespread faucets is not designed to be removed. It is built into the aerator assembly and is part of the faucet’s compliance with plumbing codes. For higher flow, you can clean the aerator to remove debris or mineral buildup, but removing the restrictor itself is not recommended. If you want a faucet with an accessible or removable restrictor, consider widespread three-handle models from brands like Delta or Moen, which often use aerators with replaceable inserts.
If water pressure seems low, first check for clogged aerators, kinked supply lines, or sediment buildup. Sometimes a simple cleaning fixes the problem without replacement.

When choosing a new faucet, look for one with a replaceable aerator insert so you can adjust the flow if needed.
