Picked up a 525xl. Maybe this is why it was only $500?

Long story short, I picked up a secondhand tank from someone and everything works perfectly...except the plumbing.

it looks like she had custom plumbing and instead of separating the main drain and emergency drain, they are connected together.

the main issue at this point (other than not really having an emergency drain) is that no matter what I do, it’s noisy as heck. My guess is because there’s no real way to adjust the main drain to take advantage of the emergency drain and reduce the noise.

i was thinking to extend the main drain (before it connects to emergency drain pipe) and put a gate valve on it and restrict flow to reduce the noise.
Any other ideas??

You have to have a gate valve and adjust it to the flow rate of your pump so the main drain doesn't suck in air and sound like a flushing toilet. That's about it. The main drain can't be connected to the emergency drain or it will be loud. The main emergency can be connected to secondary emergency drains however, still recommended they both have individual pipes in case the clog is in the pipe and not inlet but not necessary

P.s you might be able to take out the inserts on the emergency drains inside the overflow and move them to the holes connected together making the single pipe the main drain, the gate valve can be anywhere on that pipe so add it in the end, this may save you tearing up the whole thing

Yeah, that’s what I figured. I was hoping that I could avoid that but, oh well!

for the money I paid for this tank, I’ll live. Ha

You can buy complete Red Sea plumbing kits for your model tank. I thought they were reasonable....considering the market.
Or you could copy it, you need that ball valve on the main to quiet it down.

If it where me, I would return it to semi stock plumbing using a gate valve on the drain line. The emergency drain should be a clean shot to the sump.

Take a look at this article to give you some optional ideas on fixing the plumbing.

One question that comes up allot is "How do I convert my metric plumbing to US spec?". Red Sea owners are always asking this. Here I will explain what Red Sea owners need to do to get a clean finish and conversion. Also the adapter I use can be...
