Product Questions

What is the distance of the water level (bottom overflow teeth) to the rim of the tank (assuming rimless)?
My tank is already drilled with a 1.5" bulkhead.
can you tell me the minimum distance from the outer flange of the 1.5"bulkhead to the top of the tank required to allow the overflow to work properly.
Would you still have to silicone the over flow box in the tank? Like the retrofits?

    1. Fantastic Review by Adrian

      I have always used a hang-on overflow and this is marvelous. The hole I cut was easier than I thought and the but that came with the package works great. Overall I love the unit and would definitely recommend it to anyone! (Posted on 1/16/2018)

    2. Great overflow, good price. Review by Landon M

      At ~$150 CAD, this is expensive for a piece of acrylic, but still the cheapest overflow I was able to find, anywhere. Consider that it DOES come with the hole saw bit required to drill the tank, and the price is actually pretty reasonable, especially when compared to the competitors.

      I installed this on a bordered tank, placing the included template against the border prior to drilling. Even with the deep-cut weir, it maintains a water level within the border. Eshopps put a lot of thought into the dimensions to get this right.

      My only issue with the overflow so far, is it tends to whirlpool easily on the full-siphon side. Obviously inserting a strainer will prevent this, however the flow rate drops to about half by doing so.

      I've found that inserting a 4/5 elbow in the 1.5" bulkhead to direct water to the emergency side, creates enough turbulence to prevent the whirpool, without the use of strainer.

      A removable weird would be nice, as would a lid on the tank side, but for the price I can understand why they didn't bother.

      I'd recommend to a friend. The construction, fit and finish is great. (Posted on 8/1/2016)
