Help flow battles mag 9.5 vs reeflo snapper

BucNtears · 10/25/2008, 08:00 PM

Water flow problems
I need some help related to plumbing.
When i had my 75 rr { 1 drain and 1 return} up and running I had a mag 9.5 as my return pump, The pump has a 1 inch return reducing down to 1/2 inch at bulk head. I had great flow...

Now my new tank is a 120 rr { 2 returns and 2 drains}with a reeflo snapper for the return pump... The outlet is 1 1/2 inch that reduces down to 1 inch then finally 1/2 at the bulk head..
My flow coming out is not even close to what the mag 9.5 gave me..

Giving you a better idea what I did... Off of the snapper I ran a trunk line thats 1 1/2 inches then off of that I reduced it down to 1 inch, the right before the bulk head I reduced it down to 1/2 inch.

Form what I understand the snapper should be giving me some crazy amounts of flow BUT it bearly comeing out the return lines...

Please give me some imput

remember!!! the snapper is flow based. the 9 5 is more pressure based.

I have a snapper on my 110 with an o/m and four 1" returns... 1.5" from pump to o/m 4 Xs 1" retuns...

BTW.. are you running a 2" pump inlet from sump to pump???

IMO... flow based pumps work better with larger diameter pipe and no restrictions...

Hope this helps.....

yes 2" from sump to pump.. Then coming off the pump main line is 1 1/2 then reduces down to 1" then at the bulk head its 1/2".. The amount of flow is extremly slow, Bad real bad

Why are you reducing down to 1/2"?

BucNtears · 10/26/2008, 02:48 PM

It looks like 1" bulk heads {for the returns} then the nozzles are 1/2" The returns feed 2 nozzles each.
The nozzles are 1/2"

understand???

Thanks for everyones imput

So its 1.5" out of the pump, splits to 2 x 1" to the 2 return bulkheads? These are 3/4" bulkheads (normal size for a RR). What size pipe inside the overflow above the bulkhead? Then each return feeds 2 x 1/2" nozzles (total of 4)?

Yes out of the pump its 1 1/2" then runs into a maniflod thats got T's that reduce to 1" then reduces to 1/2 at the bulk head. Then feeds the returns nozzles that have 2 nozzles{so 4 nozzles } that are 1/2

understand?"

BucNtears · 10/27/2008, 09:08 AM

My bad the return bulkheads are 3/4
The nozzles are 3/4 also x's 4

IMO I would try to stick with 1" returns... try not to restict a flow based pump..
