rr or not?

[hurtback]

is there a difference in your tank between over the tank overflow and in the tank overflow? i have a 125 just sitting in the garage, not rr,but i'm looking into getting a 210 or 260. now, with any one of these tanks, over the top overflow will have that part of the overflow that hangs into the tank.and with a rr tank, you have an even bigger black box sitting in your tank, whether its in each corner or in the middle back of the tank.
Is there really a difference, besides looks, in how the different overflows work in keeping the tank clean

overflows generally works the same.
but i hada choice, i would prefer one that doesnt occupy any in tank space anyday.

YES! there is a big difference.

Hang -on overflows ALL tend to lose syphon at one time or another. When the water stops going out of the tank, but the sump pump is returning water to the tank, you'll end up with a wet floor.

If the tank is drilled, there's no syphon to break. When the water level gets above the overflow, it dumps into the sump.

If you don't like the look of overflow boxes in the tank, check out external overflows (my personal fave) or bulkhead/strainer overflows.

oh, i didnt think he meant hang-on overflow with a syphon tube.
dont get that unless u like water on the floor.
i was thinking build in overflow outside the tank.

 

[hurtback]

yes, i did mean HOTB overflows with the u tubes, not with the small round tubes, there more like big wide tubes

I don't think I've ever heard of ANY brand of hang-on overflow that didn't have a flood at one time or another.

For the cost of the overflow, and carpet cleaning/hardwood floor sanding, I'll go with a RR tank anytime.
