Low water flow can be frustrating. Especially when it affects your everyday activities. Fortunately, there are many problems that can cause low water pressure. We will show you how to fix low flow faucets step-by-step in this blog.

These troubleshooting techniques will allow you to restore your faucet’s water flow, and have it working properly once again.

Clean the Aerator

The aerator is located on the tip of your faucet. The aerator can be clogged, dirty, or both. The aerator should be soaked in vinegar overnight to remove any mineral deposits. Rinse thoroughly with clean water and remove any debris. Attach it back to the faucet.

Check the supply Valves

Check that the valves underneath the sink are fully opened. If the valves are partially closed it may restrict water flow from the faucet. Rotate the valves in the opposite direction to make sure they are fully open.

Water Supply Lines Inspection

Examine all water lines attached to the faucet. Over time, sediments and debris may accumulate causing a reduced flow. Close the valves and disconnect the lines. Inspect them for blockages or clogs. Replace or clean them if needed.

Clear blockages in the Faucet Body

If you continue to have low water flow, the problem could be in the body of the faucet. Close the water supply and disassemble the tap. Inspect the components to check for blockages. Use a soft toothbrush or brush to remove any minerals or debris.

Replace the Cartridge or Valve

Some cartridges or valves can be faulty and cause low flow. Consider replacing the valve or cartridge if cleaning faucet components is not enough to resolve the problem. Consult manufacturer’s instructions, or get professional assistance if you need it.

Check for plumbing system issues

If the low-flow issue is only affecting one faucet, then the problem most likely lies in the fixture. If multiple faucets are experiencing low flow in your home, the problem may lie with your plumbing system. Contact a plumber to evaluate and resolve any system-wide issues.

Install a flow restrictor

It is possible to intentionally reduce the flow in order to conserve water. Consider installing a new flow restriction if you want to improve the flow while maintaining water efficiency. Consult a professional plumber or choose one with a high flow rate.

Regular Maintenance

Preventing future problems with low water flow is essential. Include regular maintenance in your routine. Clean the aerator. Check for leaks and blockages. This proactive approach helps maintain optimal flow of water in your faucets.
