Beautiful indeed, but I still miss this girl plenty. Cannot believe she just vanished with no trace.

She is beautiful.

Was looking at this on Diver’s Den, but I am trying not to add anything right now.

Ugh. Double post. Live sale has caused me a couple this weekend. Even a couple triple posts. I am all for live sales for the site, but posting and reading is almost useless.

That's what is going on... I was wondering why it was so slow. WWC always crashes the site when they do a live sale.

Yep. Practically unusable all weekend. I did the taxes instead.

Thanks guys. I'm trying to learn so I can at least have some basics. So far I have learned I probably need to get rid of the old plumbing and start fresh.

 

[Katrina71]

I have to know piece by piece. Names, sizes, threading...the diagrams I have found have been good.

 

[Katrina71]

It has been suggested that I use 1" for everything. I would love to have uniformity so it's a no brainier what size to get.

Hard lose very nice looking fish.

I use 1" on drains up to a 180. Then 1.5"

I end to use 3/4" on returns but you could use 1" to keep things simple.

My tank is all 1" plumbing. Regulated main drain with strainer on the top and spears gate valve, open emergency, and return goes into two 3/4" locline.

I have some questions. I'll know more when I really get into it. I was wondering if I could use 3/4 return. Is there a reason you do this? I am wondering if I had the same thoughts.

3/4" is fine for your return... this chart will help you understand why 1" is so common for drain. With gravity as your flow force, 3/4" runs the edge on not being able to drain enough water on most setups. 1" is plenty.

Under pressure, 3/4" can flow up to 1400gph, but can drain only 660gph.

I used to have a graph that showed head loss given the size of the pipe. Back then, 1" pvc was about twice what 3/4" was so, when the chart showed only a very slight increase in return flow going up to 1", it wasn't worth it.

Conversely, the flow through a 1" drain was significantly higher than 3/4" so it was worth the money. Nowadays, PVC is so cheap it doesn't make a difference too much. But, being old school, I stick with what became a habit.

It has served me well over the years.

Well, as I was typing that @Robin Haselden found the chart!

It went all the way up to 8"... but I though that was a bit overkill and cut it off at 2"... because some HUGE tanks run 2" drains.
