Plumbing Help

[Miller Aquatic]

So I bought this 180 gallon tank and sump and he had another sump connected to it so the plumbing had to be completely redone. Two of the holes I’m using 3/4” returns and the other two drains tubing are 1.5” waiting for a 3/4 barbed bulkhead to come in for the returns. The lid that connects the drains to sump’s holes are too small and I don’t know how to connect the 1.5” hose to this lid.
Also the return is starting at 1.5” hosing with a t and converted into 3/4 would that be a problem?
I orinally had trouble finding a 3/4” barb that fit the 1.5” hole and bulkhead. I’ve never plumbed a tank before and it has been nothing but headaches.

Fixing someone else's mess is never fun.
If you give me some more pictures I'll try and help.
Not quite sure what I'm looking at here.

You could use a fitting in the 1.5" hole and the use a bushing reducer to the size fitting you want. There are lots of sizes and availible is various combinations of glue (called slip) or threaded.

Yeah he originally had it all the bulkheads and fittings with it but he didn’t care enough to unscrew the hose clamps and cracked them.

So I’ll try to give some more pictures. The braided is the returns and the clear is the drains.

I’m trying to figure out how I’m gonna fit the clear drains to this( the top lid of sump)

Does it need to be attached or can the hoses just go through the holes?

Or is it that the holes are too small for the hoses to fit through? If so, could get a hole saw and drill them out bigger.

They are too small for the hoses to go through but since it’s acrylic I’m a little nervous to pull of the saw. I didn’t think I should just shove them through I thought I was supposed to attach it to a fitting or barbed something?

There is this but the drain hosing is 1.5” and that connector is 3/4”. Not to mention I still wouldn’t have a solution for connecting the hose to the 90.

That’s a good idea but I thought I should have a bigger drain size than returns? My return is 1200 you I think

Holesaw. Lots of sizes available. Find the bulkheads you want then find the right size holesaw just big enough for the threads to fit. If you drill a hole thru a piece of plywood or mdf first you can use that as a guide over the acrylic to keep the holesaw in the right place. Have someone help hold it or duct tape it where you need it.

Some hole saw arbors have enough thread to double up 2 different sizes so one fits the existing hole and the other makes the bigger size you want.

New holesaws are VERY sharp and want to "grab" when starting a hole so dont use too much pressure and start slow if you dont have experience doing something like this and hold the drill firmly.
