plumbing drain line

Hi guys! I recently bought a new tank, now I’ve been working on plumbing it for a couple days and it’s almost done! Just came across some concerns I noticed my overflow box has water intels above and below (like the drawing I attached) so I’m concerned that my main water drain PVC will drain a...

Hi guys! In the past few days, I've been working on plumbing a new reef tank I bought, I chose the Herbie overflow method, so I placed my main drain pipe about 5 inches below the emergency one, so the problem is that my new tank comes with an internal overflow box that has water lintels above...

I have never plumbed a closed loop system before. Recently purchased a 300 gallon aquarium with 1.5" bulkheads on the returns. Having a difficult time deciding what the best way to connect the 3/4" loc-line. Any links, tips, info you can share? I haven't purchased and loc-line or adapters just...

Hi, I’ve just bought my own display tank as I fancied doing my own setup, stand, sump and plumbing etc myself. Im stuck between which overflow to buy between the 2 types attached. The shorter box would be good because it takes less space, however it means the plumbing is at the back of the...

Good morning, reef dudes. I am currently brainstorming ideas for a mixing station setup in the house I am having built. While I have a solid plan in mind, I am unsure about the idea of running PVC pipes through a finished wall. My main concern is that this would make the plumbing inaccessible...

I drilled a 2.5" hole in my 46g tank for an overflow box on one side but now I'm thinking I'd rather have the return line there. Long story short, I'm thinking of putting the tank in a different location where the drain would look much better if it was on the other side. :rolleyes: According to...

Hello everyone, I need some guidance here. I have a 30G DT with a 10G Sump I have just finished setting up. I was going to use a HOB overflow but have heard horror stories and with my work schedule I DO NOT want to risk a flood. So I will be pulling most of the water out my tank and moving live...

There's two valves I'd like to plumb horizontally. Can I achieve full syphon with a gate valve on a Herbie main drain, if the gate valve is plumbed horizontally? Will a Y-style check valve (pictured) still work properly, if plumbed horizontally? I believe this is also called a Wye Check Valve...

I am in the process of setting up a new 125g display tank with a three drain Herbie overflow from Modular Marine. I have my primary drain flowing to my fleece roller and the emergency drain dropping directly into my pump chamber with and air gap so I will hear audible splashing and see bubbles...

I've decided to add a smaller nano tank about 25G to the sump of my 90G. I'd like both tanks to be filtered by the same filter roller - hopefully a single one. Can I use a tee fitting to plumb the main herbie drains from both tanks into the same filter roller (Clarisea)? Or is it gonna make my...

Hello I’m currently installing an aquarium in my wall and need some help with the plumbing as I am stuck. Hopefully I have some fellow reefers out there that would like to take part on this journey with me because I could sure use some wisdom. I have a 220 gallon custom tank drilled at one...
