Question On Pump Output

[Sewerat]

I have my sump in basement on the floor. Height is about 7'. Then to top of DT is about another 4' so in total about 11' head. I do have pipe making assortment of turns and elbows to get it where I need it. But I don't feel like the output is what it should be. I'm using a mag 18. In specs it should be about 900gph with that head. I am piped thru 3/4" pipe. Is there a better pump. That I should use? My sump is not drilled for external pipe could be but would rather not. Is my pipe effecting flow?

External would be the way to go especially with all the fittings. A 90 will add the equivalent of 3.6 feet of pipe

a mag 18 isnt a pressure rated pump,you can use an pressure rated external without drilling

Could you switch to hose instead of pipe? You could eliminate any sharp turns, alleviating unnecessary resistance.

i use hose

Go to a mag 24? lol. thats what I use. And I have more head to battle through than you.

My Jebao DC 12000 goes up out of my sump, down into my crawl space and up about 10' all through 1" pipe with 7-90 ebows and 2-45 elbows.. It returns on a full syphon 1" pipe with a second for trickle. It is also feeding my reactors and water change tank. Might want to give it a go, and for the price of them, you can not really go wrong.

I had thought about mag 24 and the jebao flex hose isn't really a clean option I want to use. Also I don't like hose barbs restrictions

Jebaos are nice and on sale at krakens. I use tiger flex on mine ( think that's what it's called ) no barbs and clamps. It's glued right into a standard PVC fitting.

 

[theyangman]

Tigerflex is a brand name. It is just spa hose

 

[bart84]

Ok thanks tony

 

[Sewerat]

Ya but when I've got about 30-40' total distance of pipe. That's a pile of cash for tiger flex

 

[TORX]

Ouch. That is a lot. I was thinking about spa hose as well, but haven't looked at price. I have 60' just going across, that doesn't count my verticals and sump area.

 

[bart84]

Wow. Ya that would be to much money. I think it's about $5 / foot.

30' of straight horizontal run @ 600gph in 3/4 hard pipe is good for approx 7' of additional head loss.

 

[AdInfinitum]

You can couple spaflex to hard pipe so you could have hard pipe for the straight runs then flex where you need to make a series of bends....

Vinyl tubing is much easier to work with I find than spa flex and it is about half the price. I will be converting my 90's over to vinyl tubing when I re-do my plumbing this summer.
