Dual Maxijet 300gph or single Eheim 1250?

[Metalloid15]

I found that an Eheim 1250 would cost just a few dollars more than two Maxijet 300gph's. So what would be better to get?

If I run the two Maxijets in series, I would get more pressure than if I ran the Eheim, and they are both rated for the same flow. Also, if I went with the two Maxijets I would have a backup just in case one died. I know that Eheims are supposed to be very reliable, but I figure that there is less of a chance of both of my maxijets dying than one Eheim.

What do you guys think?

[Holsum]

Just go with the Ehiem 1250 and save your money that is your best bet, but if money isn't an issue get Dual Maxijet's and then yes it will be a backup if one fails!!!

[Metalloid15]

The two maxijets are $8 cheaper than the one Eheim.

[Metalloid15]

There is one other possibility. I know some people have said that Via Aquas are junk, but I could run 3 of them in series for cheaper than the two Maxijets or the Eheim. That would be a lot of extra pressure, and I can't imagine all 3 of them failing at the same time.

So what do I choose?

[bafbrian]

The more the better, I say that 3 are better than 2 and that 2 is better than 1.

[Metalloid15]

Or I could go with two of these (http://www.logiccooling.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=LC&Product_Code=700&Category_Code=P).

3 pumps in series? you're kidding me right :rolleyes:

Just go with the eheim 1250 ;)

I am using the 1250 with a cpu block and gpu block,never had a problem (touch wood). The vibration (its barely bearable) can be dampened by putting those foam sheets that come with motherboard. Use velcro to attach the pump

Maxijets or Via Aqua are not my options

A Danner Mag pump would be my next one if this eheim ever fails

[Metalloid15]

No I am not joking about 3 pumps in series. Is it really that ridiculous?

I just don't see any reason in spending 3x as much money just to get a certain brand of pump that is "more reliable," when I could spend that same amount of money and get 3 times the pressure and 3 times the reliability by buying 3 cheaper pumps.

[snyper1982]

your not getting 3 times the reliability, cause if your using all 3 at the same time, odds are one or all will fail before the ehiem, just my .02

[wolfio]

why use 2 or 3 crappy pump if 1 iwaki can do the job lol

Could you please explain why?

I just looked those up, and WOW, they are expensive.

That's why.

[Excelsior]

3 VIAs are great. I have heard of VIAs dying yes.. but i have also heard of EHEIMs dying... Just go with 3... i bet you anything that at least one of his 3 pumps will continue flowing long after an eheim would.

[Metalloid15]

And if one of my Via's does die, I can replace it for much cheaper than I could replace an Eheim.

I have made up my mind, 3 Via Aquas in series it is. I was thinking about going:
resevoir->pump1->pump2->rad->blocks->pump3->resevoir

they are expensive but you get what you paid for. Go cheap and face the consequences later on.

[snyper1982]

well because you arent keeping one running all the time and having the other 2 as spares, so all 3 are running. now if you were to do it like that, then yeah, i would say that it would probably last longer. i know eheims die as well, but an eheim is much less likely to.

[[EG]~NaTz~]

well here is what u have to look @, the via aquas put out a lot of heat while the maxis dont. maxis are reliable as are eheims and via's. the maxi's get a little bit warm externally and tend to heat the water slightly more than a eheim. if u are running a heater core before the water block the heat will not be an issue when using 2 maxi's, but if u use 3 via aqua 1300's it will be almost 60-70 watts of heat extra. oh and via aqua 1300's cost 3 dollars less than maxi jet 1200's so it would be a close price. i would go with 2 maxi-jets, and call it a day. i feel that when u buy a name u are buying a lack in gph, a name, and a good bit of reliability. i will give you that. these pumps are reliable.

[gizxmo]

i am concidering 2xmaxis going into their own radiator then into a Y connection to the cpu
might do it as these are really cheap and are small

[Metalloid15]

Natz, where are you getting Maxi's from so that they are $3 more than Via's? I can get the Via's for $15 a piece off of ebay. If you can show me a good deal on the Maxi's I might get them instead.

And I am putting the heatercore after the pumps so the pumps won't add to the water temp.

[masitti]

3 pumps in a series? Bud, don't waste your money. Get 1 pump, and a program that can shut down your computer if the temps go too high. It's as easy as that. There is no reason, at all, to run 3 pumps in a series... even 2 pumps is pretty useless. You aren't getting any extra flow because it is in a series, so don't waste your money.

People are intitled to there opinions but I am currently running a Via Aqua 1300 inline and have been for 8 months now with no trouble, i recently purchased a Maxi-jet 1200 because of the size and was not overly impressed with the flow compared to my Via, it has been sitting in a test loop for a week and I am reluctent to change to it as the via is still doing very well, I would definatly buy another via:)

I am probably only going to get two to save some $$$. I know that I won't get more flow, but I will get more pressure.

Isn't flow and pressure tied together here?

[JFettig]

why all those pumps when you can go with a danner! danner mag #3 pumps 350gph, and 10.5ft max head. thats only a few feet lower than the iwaki, and 2x the maxi and eheim! MUCH MUCH more pressure! Im running one right now, Very quiet. and from what others have said about them, they last a LONG time. People like Colin and diggrr have been using them for many many years in their computers.

[Metalloid15]

The Danners do look good, but there is still the price issue. The one place I saw danners wanted $80 for the 350gph (I am sure it is cheaper at other places). It has twice ther pressure of Via, Maxi, and Eheim, so two Via's should be about the same pressure as a Danner, with same flow, for about $40 less.

I will see if I can find some cheaper places to buy Danner pumps, and if anyone knows of a good site please give me a link.

[[EG]~NaTz~]

yes i use a danner mag 7. danners are great for pressure, head and gph. awesome pumps.

i wasnt aware that via's went for 15 on ebay. i was thinking of the 21$ on marine depot or something and i remembered seeing maxis for like 25 somewhere so then it was 4 more dollars but hey close enough.

[JFettig]

I got mine for $35. search on the forums for them, theres a link somewhere. I dont have it right now.

[therudyq3]

well it depends on what kind of setup you're gonna use. Frankly I think that 1 pump will do the job.
Multiple pumps only add more noise and heat which just simply defeat the purpose of a WC.
So I'd go with one good reliable pump.

[Stedeman]

you can get the maxi-jets for $20 each at big als http://www.bigalsonline.com/cgi-bin/index.cgi?inCUR=US and also the size of 2 maxi jets is still 1/2 the size of 1 Ehime

[BosHaus]

Will 1/2" ID tubes fit a danner without any mods?

[Giblet Plus!]

Nope. You need barbs from homedepot. Mine were about $1.50 total. :)

[BosHaus]

Danner Pumps (http://www.petsmart.com/fish/shopping/water_pumps/products/product_770.shtml)
I found some here pretty cheap, there may be cheaper places though

350gph for $45, 500gph for $52, 700gph for $55
+ $7 shipping

which of these would you recommend getting?

[Metalloid15]

Oh I had seen those Danners before and considered getting them, I just didn't realize that they were danners at the time.

Big Al's has some awesome prices. Via Aqua 1300s for $15. Via Aqua 2600 (740gph) for $28 a piece!!!!

So a Danner 700gph (go ahead and scream overkill, I know someone will do it) is about the same price as dual Via 740gph pumps. Tempting it is. What do you guys think? How is the pressure on one Danner compared to the pressure of two Via's?

[Metalloid15]

Up

[Metalloid15]

Up

[Metalloid15]

Any opinions?

[HoratioJackson]

ok... now im not sure... but if you put em in series its not gonna speed up the flow, the second pump would only speed the water up if the first pump wasnt running at max capacity, because they are both turning at the same speeds right?

[gizxmo]

yep getting my second maxi by the end of next week and they each flow through their own radiator will get digital camera to post pics prolly done in 2 weeks to a month
