Made my faucet run like new.
K1178A Adjustable Aerator Assembly
First time using this part on my Dishmaster. Have well water, time will tell how this filter works for us.
Although aerators have a built in filtering device, they are not meant to be depended upon as the primary filter. Especially whenever the water source has a persistent problem with debris, there should be a primary filter placed where the water enters the home.
