Thanks for all of the input from the Pros on this forum and to Terry for making this site available. It sounds like one check valve is all that's needed.

Apparently, Goulds requires additional check valves every 200 feet above the pump per the technical data publication that Patrick provided a link to - so you could end up with more than two valves with a deep well. It also says that water hammer is caused by the water column reversing directions...

Layman's Summary Thanks for the input. It sounds like there is less than total agreement on installing a second check valve before the pressure tank. The pump manufactures seem to require it while a few of the Pros think that it will cover up a problem with a defective check valve at the pump...

I'm sure this topic has been covered before but I did't find the thread when searching. Should a check valve be installed between the submersible well pump and the pressure (bladder) tank? I know that all (oe most) submersible pumps have built in check valves but there seems to be some...

You might also consider using preformed (as in curved) automotive heater hose which should be available in the diameter you need. At least you won't have to worry about kinks.

Can't you just solder a 1/2" male threaded adapter to both ends of a short piece of 1/2" copper to get any length you need? I've done this several times since I don't have a thread machine and sometime need a non-standard length nipple. :)

Now, I have a better idea of what you're up against. Any chance you can remove the short section of pipe from inside the hub after you cut it off. There are some special drill attachments to do this or you can use a saw blade to make a few cuts lengthwise inside the pipe and then carefully peel...

Can't you install a coupling and then use a standard size reducing bushing inside the open end of the coupling? I've never seen a PVC busing sized to fit inside a pipe. Just a thought.

You could take a short piece of half inch copper and sweat a threaded adapter on each end to make the nipple the exact length you need. I've done that on tub spouts before and it should work for a shower nipple as well.

When making a cut with the PVC pipe in place, I put a metal hose clamp around the pipe (like a car radiator hose clamp) and use it as my straight edge. It helps make for a nice cut. :)

Dual Dishwashers Thanks for the info Clayton. I didn't know that a dual inlet airgap was even made. I guess I'll have to start looking for one. HJ, I was originally considering your suggestion but thought you would want the discharge from the dishwasher to go though the disposal in case there...

Maybe this topic has been covered on the forum previously but I haven't been able to find it. I am building a new house and want to install two dishwashers - one on each side of the kitchen sink. It may sound like we're lazy but my wife and I thought it would be an interesting idea to store...
