Thread: Ejector Pit servicing valve

First time I've come across on an ejector, assume its for servicing. Can someone give me some professional verbiage for the report? Thanks. Could only make out ---Magic on contraption.

I believe you are looking at a valve which is above a one way valve with union.
Pushing the T-handle in stops back flow for servicing lower valve.

Yes, it's a gate valve, or knife valve.

Yeah, looks like a gate valve. Never actually seen one of those installed in an ejector line.

The top valve is a blast gate typically used in air or vacuum systems. Not sure it is rated for use on pressure water piping and that line is under pressure from the pump and from the static head when the pump is off.

The valve below it is a check valve.

Thanks gents.

Not sure those gate valves are rated for that use (in a house), but those are used in RVs for the gray water and black water tanks for emptying the tanks, then closing the valves off. Those valves are prone to leakage, minor leakage, but leakage nonetheless.
