Is it ok to connect to the primary pumps PVC before the check valve, eliminating the need for 2 check valves?

Not sure. I added the separate piping and check valve and made for a "cleaner" installation. It might depend on the space you have available but if you cut the PVC to accomodate only one check valve and your not happy, you will have to redo everything.

Absolutely NOT! You must have a check valve for each pump. Otherwise, the pumps will backfeed into each other, so that NO water gets pumped out.

I am really sorry, but I have no idea. We bought this based on advice from my father-in-law, and he is going to install it next time he is in town (in July). It's just sitting in the box still.

If I understand your question correctly, you're asking if you can use one check valve for both the sump pump and the battery backup, the answer is yes, as long as the two line tie into one line, but the system won't work as efficiently, you loose pressure from either pump, I had the same configuration and added a check valve for each system and the pumps work much more effectively and less noise from the systems.

I agree with the first answer. I had mine installed by a professional plumber and he requested I get two check valves for the installation and each pump has its own check pump.

Normal plumbing practice is used and nothing special. A connection valve can make installation a bit easier and is sold on amazon.

The check valve can screw directly into the pump just make sure you bring the garden hose adapter supplied with pump with you to lowes or Home Depot so you get the right size threading and diameter check valve. then connect the garden hose onto the adapter (provided with pump) and screw onto check valve.

two thibgs; 1. a chk valve will make a longer life in the pump. 2. there is a drain plug in the front housing at the bottom.

Sorry J, I also purchased a septic pump and gave you instructions for that. I would still use the quick connect valves.

You would unless the device you're connecting to already has a regulator. It won't work well if two regulators are connected. On my RV, i have it connected to a three way valve before the tank regulator.

We attached our discharge hose to 2" PVC and routed it to our 1500 gal water tank. Works great. At least one Discharge hose first, of a length of your choosing, then PVC- will give you room to shift the pump as necessary.

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.

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.

I would say, in my experience no problem. I am pumping up 15 ft before the pump and running with PVC and Garden hose at least 50ft after the pump with 3 Rain Bird sprinkler heads and it works great. As I said in my review, make sure you buy a foot valve and prime both the pipe and the pump to get it started. Also use PVC and not garden hose to pull the water up the vertical haul. I like the pump. It works great for me.

Previous comment is right on -- this is for dedicated pump on/off switching.

i use a standard galvanized reducer to bring outlet on pump down to a standard 3/4 inch house adapt. but should have a vertical check valve at the pump out let if hose discharge is above pump , or water could just run back into pump making it cycle much more

there is an intake for 1 1/2 pvc, but I have a fitting that is 2"...got an adapter for it works great....My pump has never failed me...2 years on all the time..never an issue

I am using two for sump pumps. Be sure to use a check valve if you're lifting the water very much or it will back flow when it turns off causing it to keep cycling.

Hey Tom I use a seperate pp from the main pump if that's what you speaking of. All pools I've had I've always run a seperate pump. I hope that helps. Allen

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

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."
