Good afternoon, everyone.
I have a 55-gallon aquarium, and I’m considering drilling a single 45 mm hole to connect an external PVC pipe leading to a sump. My main concern is whether it’s safe and efficient to run only one drain line.
While doing some research, I found a device that specifies a 42 mm hole for installation. I’d like to know if anyone here has experience using it, and if it actually works well with a single drain setup.
In my case, I’m planning to drill a 45 mm hole, install a black internal overflow box inside the tank, and run PVC plumbing on the outside directly down to the sump. Do you think this configuration would work properly?
I was a bit worried about relying on just one drain, but I’ve noticed that these systems are designed to handle both the drain and return through a single bulkhead. I’d really appreciate your feedback on whether having an emergency drain is still necessary in this kind of set.
product specifications :
Exterior Dimensions - 4.7" L x 4" H x 2" W
Max Flow - 660 GP
Drain Hole Size Required - 41.5mm - 44mm (we suggest using our 42mm Glass Drill Bit)
Drain Plumbing Size - 40mm or 1.5" Soft Tubing
Return Hole Required Size - 27mm - 32mm (we suggest using our 30mm Glass Drill Bit)
Return Plumbing Size - 23mm or 3/4" Soft Tubing
What's included?
1x INOUT External Box
1x INOUT Internal Grid
2x Bulkhead Nuts
2x O-Rings
1x Spare Return Nozzles
1x Drilling Template
