Plumbing pics

[thirty6]

may get courage to layout some plumbing soon and would like to see some pics. I pretty much have concept but i may switch to external pump and have to reduce from 1" to 3/4 for returns and throwing me off a little
*****

Going to use manifold with ball valves for equip and relief drain from pump
Drains on tank are dual 1"' with dual 3/4 returns

Thanks Ken,

That's a clean looking setup. I need to pickup few more unions I think.

Ken, awesome setup. Super clean!

Thanks guys

I didn't line the holes up rt when i drilled: have to redo
Have someone coming by Monday ( i hope) to help out

Looks awesome very intimidating but,I have to get started on mine soon just picked up all the pipes and fittings from home dept but I need one more thing home depot doesn't carry ck valve for a 3/4 return line anyone know where I can get one without having to order one?

I thought lows had more PVC fittings than hd, had section of hose barbs and the boxes were actually marked!

When plumbing in PVC just remember to always use wye's wherever you're thinking you might need a tee.
Also try to use 45's if you can avoid 90's (not always possible, but worth attempting).

@ NYCTURBO - there aren't many folks who would recommend using a check valve in a saltwater environment. I would rethink that plan. They tend to fail and offer a false sense of security.

I thought the ck valve was put as a security blanket for pump failure?

To Russ listen, wise, he is.

Check valves are known to fail in a saltwater environment just when you need it most. If you're talking about using one on your return, the "better" way to avoid a back siphon/sump overflow/flood is to put siphon breaks on you return nozzles and/or keep them high up enough in relation to your water line that air immediately rushes into the nozzle(s) when the pump is off (or all the time, if that fancies you)

I found that the Manhattan Home Depots are annoying when it comes to PVC fittings. Not surprising given that PVC pretty much isn't used in the city by code. They seem to just not have the stuff out on the shelves...but the solution seems to be to use the HD website to order the stuff you want, then pick it up in the stores, including the ones in Manhattan...though it seems that the 23rd street one is more liable to actually have it in the back room there. Annoying as I live near the 59th street one, but yeah.

Course if your'e not in a hurry, https://www.savko.com/ has everything and then some, and is cheap.

In freshwater applications I can accept that. In saltwater applications there are other caveats to be aware of. Calcification of the valve can prevent it from operating properly, hence the false sense of security. Like our resident Jedi just said, incorporate siphon breaks into your plumbing design to accomplish the same goal as the check valve. This is done without any mechanical device that can possibly fail.

Limiting the potential points of failure will ultimately increase your overall, long term success.

Thanks for the advice.

 

[thirty6]

How many siphon breaks would you suggest?

Anything other than small ole in loc line and having higher in water?

I might just make that my sig. Good one Russ bud

I have 2 return tubes (the black plastic J type basically) going into my display. The nozzle for each is pretty low in my water so I drilled 2 small holes (1/8th" i think) in each tube, right at the normal water level (maybe a hair below). So when the return pump turns off, water only backs down the drain a tad bit, plus what's in the drain line.

If you're going the drill hole method (as opposed to having the return opening at the water level) then 2 holes are always better than one...there's always some salt build up on the hole which could cause a clog, and thus a siphon, or some other debris, or a snail sitting on the hole just when you don't want one to...

Speaking of, there's currently a nickel sized nerite snail in my overflow...i can't reach him, thus he's staying there. Hope there's food! I'm pretty sure that's the one that decided to hang out on my floor one day too. He's uh... dense.

Thank you that helps I'll look into the 2returns instaed of the one I originally wanted to to that but I didn't want to complicate the plumbing wanted to keep it simple but it doesn't sound like a big deal.

Nope makes sense to me. Thanks
