Overflow question

[jake15]

I have a 29 dirlled with a 1 inch drain and a 3/4 inch bulkhead for my return. I have a mag3 for the return pump.
I have 1 inch pipe going down but i was wondering what size i should use for the return 3/4 or 1/2 ?
Thanks Jake

I would use a 3/4 and bump your pump up to a mag 7

 

[jake15]

If i did this would there be no problem with overflowing of the tank and could i run the pump wide open?

 

[sign guy]

yes ether pump will work fine

 

[sign guy]

how much head do you have?

 

[jake15]

Not sure what head means. I would like to use the mag three if possible. I know a mag 7 would be much better but the only pumps i have is a mag 3 and mag 12 and money is kinda tight at the time. So if i go with the mag 3 what size pipe do i use for the return?

Still use the 3/4" line...to get Max flow out of smaller pump...
And then it's set for when you can get the next size up...(5 would work, 7 would be better and still work with you overflow)

Ok what kind of fitting can i use for like a quick disconect for above my pump when i want to switch it.

 

[sign guy]

you will just have to go to home depot and check out what they have
head is the amount of gph you loose going straight up IE my mag 9 on my 46 is only pumping around 600 gph cuz it has to go 4 ft up

 

[jake15]

Well i got it all hooked up and the over flow is really loud what can i do about this

Try setting up a Durso standpipe

 

[wattsupdoc]

Google a Durso stand pipe.

How could i do that? I have a durso pipe for a 1 inch bulk head but i do not have the tank drilled for that and i already have my pvc glued. Here is my setup

 

[jake15]

I have a 29 dirlled with a 1 inch drain
Why won't it fit..??

 

[jake15]

Mine isnt drilled on the bottom. its drilled on the back. Dont they have to be on the bottom?

 

[squidd]

Not neccessarily...
How far down the back is it drilled..?
Check the Durso site for thru the back installation options...

 

[jake15]

all theirs seems like they are at the Top of the tank. Mine is low in the back. And it also looks like they dont have an overflow. I have an overflow and as stated before its close to the bottom. Also my drain is bent up at a 90 degree angle. could i do this?
Normal 1 inch T fitting with cap and hole in the cap?

You can see in post #13 2nd pic how low it wasdrilled.
