The instructions list a check valve installed above the unit. I don't see any "Heavy Duty Check Valves" as part of the system. Is this right?

Mine came with 2 check valves. One for each centrifugal pump. Otherwise with only a single pump running it would be back flowing out the other pump. A third check valve in the line past these can't hurt but shouldn't be necessary...

Pump includes two check-valves, one on on the backup pump and one on the primary pump. They are actually located at the bottom, where the white PVC pipe connects to the pumps (just under the rubber pipes). You can see the diaphragms if you look down the pipes before you have installed it. Note that the instructions included are incorrect in several ways because Wayne sends the instructions for both devices, not the components as a whole (which includes the check valves). In my case, I left my existing check-valve as an extra pre-caution and haven't had any issues. As an aside, the instructions also indicate that you need a weep hole. However, Wayne's website indicates that one is not necessary because "Wayne Sump Pumps are designed with a top suction inlet. This design naturaly [sic] prevents airlocking [sic] which eliminates the need for drilling a weep hole."

I would highly recommend a check valve in your case. And I would suggest you locate it as close to the input end as possible. Retaining as much water as possible in the water line should help with the prime. Caution. Occasionally check valves will become clogged with debris and therefore I would clean from time to time. It does NOT have a check valve included. Needs to be at least 1 1/2 inch.

The valve body is included; but the valve doesn't have "stops" on the hot and cold incoming water lines. Some areas of the country require stops to pass a local inspection. Your plumber or local plumbing supply house will have stops that can be added for compliance - if needed.

They just want you hooking it up to the backup one is all, the pipe that goes to a 45 to the main discharge. I did exactly what you're asking, put check valves right after it just like how you hookup a Watchdog battery system. If that's what you have right Now like I had. I took that 600 piece garbage out. This water backup one works awesome! Worth every penny, and it's 1/5 thr Price of the Best Watchdog Battery System.Another suggestion is I used those rubber inch & half elbows with hose clamps on each instead of using PVC elbows. Worked great for me and it's not nearly as Rigid.Google this also & click images, youtube video is also good Have a Great Christmas They just want you hooking it up to the backup one is all, the pipe that goes to a 45 to the main discharge.

All sewage/sump pumps need to have check valve install in order to work properly. If you have one already and it works properly then you don't need to buy a new check valve.

Not sure why or how you would install more than one valve for this system. Read the instruction manual to understand function of the valve.

The check valve needs to be placed on the discharge PVC pipe (with a male adaptor that threads into the threaded pump discharge) and located above the top of the pump.

basically a check valve does two things. If your exiting line from the pump runs level or slightly uphill, the check valve should keep the outflow on the exit side from coming back through the pump on shutdown. It would also prevent inflow from the outside back into the pump in a case where you have the pump dumping into an area that could collect outside water above the level of the exit. Both of these situations could be avoided by positioning the pump and the outflow line such that water would only flow away from the pump and to a lowspot that is sure to be lower than the pump outlet. Particularly if you are only using it several times per year. So have at it but keep the flow going with gravity not against it.

the valve is not included. You have to order it separately. The valve I order is as follows: KOHLER K-304-K-NA Rite-Temp Pressure Balancing Valve

We put in two of these in two different bathrooms in 2014. I'm 99.9% certain the rough in valves came with the package. Our plumber installed and I did the finish plumbing. I can probably find the paperwork that came with it if you can't deal with 0.1% uncertainty. - Tim

Hi larry here. I just received mine and there is a valve included in a plastic bag , no explanation but I think it screw into the unit for that purpose?? That's all I have for you

That would be a plumbers question. We have a two story home and have one valve on each floor. One in the kitchen and one in the Master Bath and they were installed by our plumber, however I replace them, very easy and a whole load cheaper.

My Zoeller came with a check valve, make sure yours does too, you definitely need it

I'll look at home tonight. BTW - I have both the extension piece and the metal valves to install the unit. I ordered two sets. If you want them, I'll give you a killer deal on them. ghforsythe@comcast.net

my previous post about check valve, might be in pump internally and not separate unit

no. the bracket is optional. i did not use one. my install went as planned. my advise: 1. besure to install 3 valves for a by- pass. 2. spend an extra $10 for a pressure gauge since filter body is opaque (not clear). this is installed post filter to monitor pressure differential from line side. helps when to determine filter change time. 3. allow enough bottom clearance to drop filter body and install replacement or install 20 plus inch body and cartridge. 4. use wraps of teflon tape as instructed plus couple additional ( tape is cheap) leaks are not desirable. be sure to use silicone ( vegetable) grease on seal and housing threads so seal doesnt dry outadv no. the bracket is optional. i did not use one. my install went as planned. my advise: 1. besure to install 3 valves for a by- pass. 2. spend an extra $10 for a pressure gauge since filter body is opaque (not clear). this is installed post filter to monitor pressure differential from line side. helps when to determine filter change time. 3. allow enough bottom clearance to drop filter body and install replacement or install 20 plus inch body and cartridge. 4. use wraps of teflon tape as instructed plus couple additional ( tape is cheap) leaks are not desirable. be sure to... » Read More no. the bracket is optional. i did not use one. my install went as planned. my advise: 1. besure to install 3 valves for a by- pass. 2. spend an extra $10 for a pressure gauge since filter body is opaque (not clear). this is installed post filter to monitor pressure differential from line side. helps when to determine filter change time. 3. allow enough bottom clearance to drop filter body and install replacement or install 20 plus inch body and cartridge. 4. use wraps of teflon tape as instructed plus couple additional ( tape is cheap) leaks are not desirable. be sure to use silicone ( vegetable) grease on seal and housing threads so seal doesnt dry outadv « Show Less
