How much flow for water change pump?

[Aquavaj]

This will be from a 32g brute in the garage to the living room. I would say atleast 25ft. The container will not be elevated. I'm leaning towards a submersible pump since they're cheaper but that means about 3ft of head at the container and another 4-5ft at the DT. I can't go to the sump because the return will spray and splash too much. Will probably go with 5/8" hose.

I've been looking at those cheap pumps on amazon with around 1200-1300gph. Would this be enough flow for the distance and head? I don't need crazy flow but I don't want to stand there for 10 mins waiting either.

Also would brass on the hose be avoided or would the short contact time make it a nonconcern?

I used to run a 1/4 HP utility pump with well over a 25 foot run and it was no problem at all.

You can use this calculator to get a decent estimate of equivalent head height of your planned plumbing run.

After you plug in your desired flow rate (in gpm), total length, pipe diameter, number of elbows etc, it'll spit back the equivalent total pump head required. Play around with pipe diameter, desired flow rate, etc. Then for whatever pump you’re considering, look at its published pump curve (expressed in flow vs head height) and find the flow you should expect at the head height provided by the calculator. That should get you close enough for government work [emoji106]

I've been looking at these utility pumps and have a few questions before making the purchase.

1. Are they fully submersible?
2. The hoses these use look to be like black vacuum hoses. Are these aquarium safe?

1. Yes they are fully submersible.
2. You can attach a garden hose or a braided flex hose with a PVC fitting if you prefer. Never had any issues.
