Auto drip drain question

[Mr Pleco]

I set up an auto drip system on my aquarium and its working well . The sump overflow drain is set up through a 1" bulkhead in the sump with leads to a garden hose right into my floor drain. I'm currently only dripping 6gals a day which based on the calculator gives me about a 40% change in water per week.

Here is the issue my electric company came out today and turned power off for a good 5 hours . Well when power came on I got a surge of water into the sump which the 1" sump drain pipe couldn't keep up with the flow.
So the sump overflowed all over the floor ... wo drilling a larger bulkhead how can I modify my existing drain pipe to handle an event more water like this surge. ...? do I need to install a standpipe to vent this drain ? or is the garden hose the issue ?

Maybe have the water drip into a large bin before it goes into your aquarium to prevent this problem in the future. Then just install an overflow into the bin. You might get more control this way, too.

This is why you always give extra room in the sump to compensate for an influx of water even if you never expect it to happen. I leave about an inch of room (about 5 gal of water) minimum in the sump. If I were to do an auto top off and overflow I would do that as well and adjust the height with a pips in the sump side.

Well when power came on I got a surge of water into the sump which the 1" sump drain pipe couldn't keep up with the flow.

I guess I don't understand your setup, but how did water come into the sump when the power came back on faster than it always comes into the sump when the powers on? Fast enough that it over flowed the sump?

Is it possible, when the power went out, that the tank back flowed into the sump and that's when it over flowed? Because if a sump has a small overflow near the top and it doesn't have a sufficient reservoir to hold in-transit water due a power loss, that it would over flow.

Upsizing the bulkhead and the drain pipe will help. I had the same issue setting up my 150. First I tried using a 1.25" bulkhead with a 1" pipe. It overflowed when I tested it so I bumped it up to a 1.5" bulkhead and pipe, that got the job done though it did come close to the rim. Also the less bends and curves you have the better it'll drain.
