Glass Holes to Eshopp Eclipse

[lion king]

I drilled 1.5" bulkhead and installed a Glass Holes overflow into a 40B, I hate it. It is just ridiculously loud. Luckily it's in my fish room or I would have already shut it down. I thought I was going to be ok with it, but I'm not.

I thinking of replacing it with an Eshopps. Will this work, I'm having some confusion if it will be a direct swap. Currently the Glass Holes 700gph overflow box, looks like the Eclipse S is rated at 600gph, which is enough; and the eclipse M rated at 800gph, too much IMO.

In the description the drain bulkheads are listed at 1", while I see a a 1.5" transfer bulkhead. So the glass holes is 1.5", is the eclipse transfer bulkhead meaning the actually hole drilled into the tank.

Has anyone else done this, not is the mood to buy it, take it apart, and find out it doesn't fit.

Best thing to do at this point, is to order one and return it if it doesn't fit.

I hate to say it but, unless someone else has done it, there is no way of knowing.

Obviously the bulkhead fittings are the same.

@Crabs Mcjones how far down was your hole drilled for your eclipse?

(I think he has one)

 

[eggplantparrot]

Yea the only problem would be the hole height and diameter as not all bulkheads are the same size. Let me measure mine after i finish lunch

 

[dantimdad]

I would bet the bulkhead size is within tolerance to fit the same hole.

 

[eggplantparrot]

Hole diameter is about 60mm

Hole from top of inside box is 72mm measured to the top of the hole so about 102mm to middle of hole

 

[eggplantparrot]

There is a little bit of wiggle room with the bulkhead, id say ±1mm each way

Is your 40b rimmed or rimless?

Is your 40b rimmed or rimless?

Rimmed, I was thinking at worst if the outside box of the eclipse is to high, I would trim the rim to get it to fit. And keep the inside box of the glassholes if the inside doesn't fit. I just think the jetplane design of the glass holes is just not for me. To just pour down a 1.5" pvc.

Agreed. Tried the same design years ago and it sounded like niagra falls with only 300GPH going through it.

Herbie for me from now on.

Do you have a gate valve or anything on the glass holes?

 

[dantimdad]

Btw, you might want to look in to the Fiji cube overflows. Cheaper and look very nice. I just ordered one. Tell him Steven sent you.

You think installing a gate valve and slowing down the water fall would help. Where would you place it, up high or down low, I would suspect down low. Easy enough to do, I was also thinking of reducing down to a 1" pipe, would that be something to consider. Plumbing is definitely not my expertise, but after having to redo 2 jobs that I professionally had done, I figured I was better than that.

Yes, but adding a gate valve you can create a continuous siphon, which wont suck any air making the drain silent. It can do anywhere in the drain line.

Glass-holes.com. What happened to them.. I can't find their website... Did they go out of business?

 

[dantimdad]

Evidently. It's just parked now.

 

[AdamNC]

Looks to be a dead site now.

Any update?

I'm also looking at swapping my Glass Holes overflow for an Eshopps Eclipse M. I believe the bulkhead size is the same, but I'm wondering about the hole height and if the Eclipse sits higher or lower.

 

[Gareth elliott]

not sure if this helps as i didnt take a picture before i put on the overflow.

This is the S. Not the M.
I do most of my flow with wave makers, huge sump turnover wasnt part of my plan lol.

I can't really judge it from your picture. I think it just comes down to whether or not the Eclipse fits in the same spot as the Glass Holes overflow.

The center of my drilled hole sits about 4.25" from the trim on the inside and about 3" from the trim on the back of the tank.

At this point I don't really care about water height, but moreso about replacing this noisey single drain overflow.

Thanks for your reply!

Dunno if this helps. One is drilled with the template and has glass showing above the overflow. I didn't like it so I drilled the other 3/8 inch to the top inner lip. Both are 29s. The pic with the measure tape in overflow is the 3/8 to inner lip.
