Single handle faucet question

[Jonathan Cartwright]

What causes some single handle type faucets to shut almost all the way off when operating?

Example: Pull the faucet all the way open - good water flow. Release the handle and the handle moves toward the closed position and water flow is reduced accordingly.

Thanks and have a great day.

JC,

Not entirely sure. I usually attribute that to wear and suggest replacement of the cartridge/valve stem or any needed repairs by a licensed plumbing contractor.

I've seen this a few times before.

Replace the cartridge or O-rings.
O-rings cost less but the cartridge is simpler.

[Dom D'Agostino]

Cheap, aftermarket cartridges can cause that behavior.

Unless it's a moen. If it's a moen, take the cartridge to the plumbing supply house (not the box stores) and they will exchange it at no charge.

[H.G. Watson, Sr.]

Sometimes the lever handle set screw or fastening nut hasn't been tightened sufficiently. As previously mentioned, sometimes it is cartridge related, occasionally a flow restriction before hand such as supply valve(s) not fully opened, kink, etc., sometimes not enough friction such as the moen pull-out/up o-ring issues and plastic cartridges. Sometimes it is the ball/socket or gear interface between underside of lever handle broken or striped plastic, nylon, or pot metal.

Thank you for the information. Excellent as always.
