Return Pump Question
 
Is it possible to tee off the return fitting and have a Mag 5 and a Quiet1 1200 running together to increase water flow? Pros / Cons?? I am just wondering this instead of having to go out and get another new larger pump as the Mag 5 is only a week old.


TIA

Can run pumps in series (increased head) or parallel (increased flow), worth the hassle (plumbing, extra fitting, space, maintenance), I would just get a bigger pump (assuming your overflows can handle).

I have a 1.5" return line and a 1.5" overflow line with an emergency 1.5" overflow straight to the sump. So I think it can handle the volume.

I just hate the idea of throwing away $90 and then having to go get another new pump to do the job that I wanted the first one to do........ Am I cheap? Or just frugal? Only my banker knows for sure :)

you won't be throwing away, you'd be posting FS in the Buy&Sell section.

Thats true.

Or see if someone wants to swap the smaller one for a bigger one (plus a little extra). :wink:

Anyone wanna trade a Mag 5 for a Mag 7 (or 9)? Prefer in Calgary because of shipping costs.... :LOL:

FWIW I have found that even with the Herbie overflow I cannot push a lot of water back through my return as I get to much splashing noise from the extra water dropping into the overflow (only about a 3" drop to the water level).

I have a peice of eggcrate angled to the bottom of my overflow and that seems to quiet things down conciderably.

That's why you adjust your gate valve until the water level in the overflow is just barely trickling down your emergency drain.

One more reason I should have used a gate valve instead of a ball valve :p

I may also try a coupling on top of my emergency line so it is just about level with the tank water line to reduce the amount of drop of water into the overflow.
