New guy question on pump/overflow combination

The height of the overflow box should not make much difference since its a siphon effect either way. Valve the discharge side of the return pump slightly to obtain a balance. Make sure you have sufficient room in your sump for backflow when the pump is off then mark that level on the sump with a Sharpie and never fill past that mark for safety.

 

If you absolutely want less flow then valve the return to the tank. Otherwise the way I see your original post is that you wouldn't have to do anything because the overflow can handle more water than your return pump can put out. I don't know how much flow people recommend buy with your setup you should be fine without restricting anything.

 

I would have thought i wouldn't need to restrict anything so it may be the way the sump is constructed that is causing there to be not enough flow (doesn't really make sense in my head but okay.). I am not using the valves on the overflow, they're just there for emergency sake and for maintenance reasons i guess. I am wondering if there is not enough flow INTO the overflow. There are two outlets for it, but only one 1" U-tube between boxes. I wonder if the 900gph rating is for if you use two tubes, or if it even matters? I never took fluid dynamis in school, just EE classes :'-(

 

If you have the second U tube i would try installing it to see if it makes any difference.

 

EE nice! I work at an EE firm. We do Process Control. I program Logic Controllers and Operator Interfaces.

 

Nope, it only came with one, so the rating I would assume that only 1 is required for 900gph. I can make one with some leftover flex tube from my plumbing adventure and see what it does...

 

unfortunately I am not using my EE degree so much. my focus was network engineering moreso than PLCs. I am an Energy Trader now... so, no real engineering skillz required.

 

Ha ha, I didn't finish my EE degree (no more money) but I was lucky enough to land a job with this company and I love it. Of course our main focus is Water and Waste water Treatment ha ha so I know a little about hydro-dynamics.

 

And I do the program or construction management, approve field changes, witness the start ups, teach the operators how to work what you have programmed and write the online O&M manuals to go along with the new sites and equipment. Much more fun than just operating the plants like I did for the previous 30 years.

 

Yeah, we have guys like you here but I hate that aspect of the project. I like to do the geek work ha ha ha. I do the training portion because in our company, it just seems more logical that they guy who programmed the system would have the best grasp of how the system works and operates (and nobody else wants to do it). We do our O&M's on paper (what a waste of resources!!!!) They just sit on a shelf and collect dust anyways. We provide a digital copy which makes way more since to me. Our company is usually subbed out by companies like yours. It is fun, start-ups are my favorite part when i get to see the code i wrote bring stuff to life. I always enjoy meeting other people in this line of work but you would be the first reefer so +K.
