New Drains



Hmm need to put Xmas decorations away









Filling it up....

Running



Was very happy with the flow at this point. Only one minor flaw . Use ball valve on drain line and wasn't as easy to dial in flow to maintain water height in overflow but easily changed. So I am quite happy at this point.
Now it was time to test emergency line, so I blocked the main drain and watched as the tank very slowly began to fill. PROBLEM .
which takes me to this thread:

water was a little higher in sump than normal and Yellowknife has a semi monthly subscription to power outages, so I thought it might be a good idea to test and see if sump could handle a power outage . Turned off pump and watched as the sump very very quickly began to overflow.
DOOOOOOOOOOO
turned pump back on with no immediate effect , closed drain line and slowly began to slow the flood. HMMMMMMMMMMMMMMMM
Grab shop vac and try and figure this one out..

Then I remember the thread about back siphoning return lines.
Another one of those AHHH HAAA moments that take place in this hobby for me.Lucky for me it was fresh water and on lino,

So for now we are ordering up a few new fittings, a gate valve, painting and sealing the stand. Drilling a hole in the back for my return line because I don't like the overtop at all.

For now the only question I have for everyone is about check valves.
As I said earlier, we get a lot of power outages, and as I haven't finalized my return. I was going to plumb in a backflow behind the bulkhead.
Is this effective or is the small hole drilled in the line just below the water level a good enough solution to the back siphon problem??

Thanks for reading

So the drain pipe is larger than the emergency drain?
Why not raise the drain pipe up closer to the height of the overflow, should be quieter and maybe even drain less water into sump on a powerfailure.
The back siphon on the return is an easy fix just drill and 1/8" hole in the return line just below the tank water level. The hole will allow air into the return line and break the siphon.

Yes the drain is bigger
As soon as my parts arrive I'm going to drill my return thru the back, going to add a 3/4" above and below the 1/2" emergency bulkhead and give it a test.

Time for an update, been busy lately and haven't had much time to post up some pics.

Cleaning gunk off the back of tank from the old background glue.
Going through back office looking for something to use and guess what worked best. Yup Overproof Rum took care of the glue in short order.




Masked it off and used Acrylic spray paint, may need another coat but we shall see when setup.



Touch up the stand with some filler



Drill a few holes to run cords out to Powerbar.

Princess Auto order arrived and I was able to get my overflow tuned up.
There was a lot of good advise on how to accomplish this because of the previous owners setup , but I came up with the following plan and have great confidence that it will work perfectly when up and running. ( I hope)
Since I have a 1" Drain bulkhead , I will adapt that to a 1 1/2 Drain Pipe inside the overflow box extending up to about 3/4 of the height of the box. With the second hole sized for a 1/2" bulkead, and not really being sufficient for an emergency drain. I decided to break open the new drill bits and bore out the hole to fit a 3/4" bulkhead. Found some adapters locally and second hole will have 1" pipe before and after bulkhead.



And for safety sake, a second 1/2" emergency drain line cut into the back of the overflow, because it was getting pretty tight in there. Thanks to a few of the members for there input on this one.








New bits mean fast drill time, minor chipping and the only real problem I found was that I didn't want to put a lot of pressure on the drill and let it do the work. What I found was that in doing this, the bit tended to sit and bore the hole out rather than drilling a nice straight hole. Nothing serious at all and I am sure after a few more tanks I will get this to work better.

First coat of Marine Grade Paint on stand.





Canopy had some water damage , so I need to remove the damaged wood and rebuild it. My plan for now is to cut out a slot that my 6 Bulb Aquaticlife fixture can sit into and slide back and forth on. Depending on what I put into it I have 3 different light fixture ready to go into it, but we can discuss this later.
