Another pump recomendations

[Mr D smack]

Im getting ready to break down my 225 and replace it with a 120. The first question is what externial pump to use. I curently have a Iwaki 100rlt. This pump is on its last leg. I searched and found that to rebuild it its about half the cost of a new one. So I decided to buy a new pump and rebuild this one later for a back up. Will this pump be to big for the turn over rate with having aproxmantly 30 feet of head pressure. My sump is in the basement and this is the reason for a high head. With this in mind if need be I will re do the or the supply. I curently have 3/4". The new tank is 5 foot long. If the 100 Rlt is too big then what are some suggestions.

Second question. What would be ideal for Power heads. I currently have some maxi jest 1200's, Rio Seio 620, and a Rio 2100. I would like to get just 2 power heads to do the trick. After doing some research I like the Turbelle nanosream. Would these work?

I bought the 225 used and would like to so to say start off with new pumps.

30' of head? Why so much?

[Mr D smack]

It comes up to 28.44 on the calc. here. I have aprox 10 foot vertical in the basementto get through the floor, with aproxmantly 6 feet horz. Thenanother 5 feet vertical to the top of tank. 4 90's, 2 ball valves, 2 couplings, and a Tee.

The sump will be on the basement floor? I dont know what your plans are, but I would suggest to put it up on a bench if possible. It makes working on it, and draining for water changes so much easier and would decrease your head.

That still seems like a lot. Horizontal doesn't count (very little anyway). Larger return plumbing (1" or better) would help.

[Mr D smack]

Yes it is curently on the floor. Honestly I never though of putting it on a bench. Guess what Im going to do over the weekend. Thank you very much . So simmple but again never thought of it. So back to the pump. Would the 100 RLT be to big. If not keep 3/4" supply line?

Here is mine on a bench. I have it set up so that I just open a couple of valves to drain the sump for a water change. The 44G Brute trash can that you can just see on the right holds salt water for changes. I connect a hose to the sump drain which goes to a toilet, open the valves and drain the sump. pump SW in from the 44G Brute next to it and water change is done. So easy!

That pump seems big to me. I'm using a Gen-X Mak4 and it has lots of flow. Some of the flow is T'd off to feed the fuge (behind the sump).

I need to update this pic. The fuge wasn't up and running yet

[Mr D smack]

I got the horse in front of the wagon. I'm planning on the 225 to go into the same sump in a year. I ill be building a bigger sump for this. So if I leave the sump on the floor as is now do you still think that its too big. I also have a T on mine for the fuge curently. Th eguy I bought this from had the main line to the tank restrictied so that might have been some of the cause of the pump going out at such an early stage. If this could be a problem I could just add anothe rT and put it back into the sump?

[sjm817]

Try it and see.

[Mr D smack]

Thanks for quick replies

[sjm817]

Are you using the same pump, or buying a new one?

[Mr D smack]

Buying a new pump. I will rebuild the one curently running later.

[sjm817]

Tough call. That is an expensive pump. The 3/4" plumbing is really small too. I'd fix that if possible.

[Mr D smack]

Yeah I'm going to swithch it to 1"

you want to run the largest dia for the longest run. If the pump has a 3/4" outltet, use a couple to change it to 1.5 or 2" and use spaflex. A side note, 1" pipe going 8' has roughly 15' of head loss due to friction in the pipe, at 1.5" it has about 2.5' of head loss.
