Yes, as I told you couple time before we ALWAYS install flopper-type check valves in vertical position - as per Zoeller instructions.

I don't think 2 check valves will be a problem. Just space them out a bit so they are not on top of each other.

I realize you mentioned that above, but I wasn't sure if you were using Zoeller's valve, which may (with my luck) be slightly different, enough to not cause a problem. That's why I was more specific this time.

Again, I really do appreciate your time and expertise.

BTW, just comparing the "looks" of the two pumps shows the better quality with the Zoeller.

Thumpernator...

You said it... zoeller won't let you down.

Read the installation instructions and check out the diagram that came with the instructions... always gives best result!

Did you drill the 5/16" hole as required to prevent "air-lock".. Let us know.

In terms of the check valve you could probably just stick with the one that is in place right now. However, I don't think a second check valve installed as recommended on the vertical will hurt anything either.

Let us know result... ;)

The flopper check valves are more-less of the same design. We like to use Zoeller brand, not the plastic one, but the one that has cast iron body.

Drop by and let us know how you did..

It's all done and everything works. Having the check valve just outside the tank really makes a difference. Hardest part of the whole job was to get the rubber seal installed in the lid.

I am a very happy 'camper'.

You guys are awesome. Thanks again for taking the time to help out us amateurs.

Mark,

I did drill the hole, but the instructions said to drill a 3/16 hole.

Don't see how you can forget that hole. It's printed on almost every flap of the box and several places in the instructions. But I guess it does happen.

Thanks for your help, Mark.

Thumpernator...

You would be amazed at what some people consider unnecessary even when clearly labled ten times... :p

3/16" hole... check... sounds right!

Don't forget to inform everyone that feminine-napkins/tampons, paper towels/napkins, tooth-floss, and mop strings (just some of the things I remember unwinding off a sewage ejector) should never be put into the fixtures going to this pit!

Glad to help...

Guess I need to find one of those placards I've seen in some restrooms at restaurants and such. Can't see myself making an announcement every time we have guests, which is quite often.

Now that would make an interesting thread; suggestions on what the placard should read. I think I'll go with, "Don't make me sad, don't flush your rag." :D

.

How about, "don't be a sap, only thing that goes down this toilet are toilet paper, pee and crap... ;)

Take care...

I do not have the Zoeller model check valve, but rather one from the local plumbing supply, and it is a flapper type.

You guys ever heard of a problem mounting it vertically? Sure would make a lot less work for me if I do it that way.

I have never installed the check valve on a sewage ejection system horizontally.

Given the macerating action of the pumps impeller, the likelihood of anything large enough to inhibit the closing of the check valve making it that far upstream are slim to none.

I'm one of those guys that didn't read the instructions when replacing his ejector pump. The previous pump and discharge pipe did not have a hole and I did not put one in. 3 weeks after installing the RIDGID SSEP500 it stopped working. Pump turns on, but does not pump. Impeller moves freely. What would happen if I didn't drill the hole in the pipe?

You may have an advantage with two check valves. If your lower one is too close to the pit to open the lid for servicing the upper one will hold the water above it. Also, I had a customer complain about the loud bang at the end of a pump cycle. I put another check valve up high on the vertical pipe and no more loud bang, just a mild thunk.
