For about $300, the standard home owner, 1/2-hp shallow well pump set-up, used at camps, cabins, islands, everywhere on the lake has one of these valves as part of the system. You buy a system at the Lakeport Tru Value in Laconia, Lowe's, Harbor Freight, the local hardware store or someplace, and it's a component attached next to the electric water pump. It's just there, it comes with the system, and not as a separate item.

Typically, the injector valve is positioned between the circular impeller pump, and the 1 1/4" black cpvc pipe. It works the same as a person's tongue while sipping a beverage up through a straw. It keeps the water from flowing back down the cpvc pipe, into the lake or shallow well .... by pressing one's tongue onto the straw.

If you get lucky, maybe just $99 for the whole 1/2-hp motor-pump-30gal tank system, at Harbor Freight Salvage in a lovely turquoise blue color? Those Chinese ...... they think of everything!

Best place around for pumps and pump items is Lakeport Tru-Value in Laconia, about one mile down the road from Lowe's, and worth the visit ..... plus, you buy local! Is the neatest, best organized, well supplied, pump and plumbing dept ever-ever-ever in world history of pumps and plumbing ... makes Lowe's look sick!
