Junction between return pump and tank?

[PapitoDelSol]

Hi,

I’m installing my tank and I want advice for how connect my return pump to the return pvc pipe.

I have a soft pvc pipe but not pretty rigid.
It is possible and easier to use silicone pipe?

Thanks

Any soft hose should be able to connect with a “barbed fitting” — these come in various sizes for various sizes of soft hose!

There are adapters that convert from hard pipe (either glued or threaded) to a barbed fitting!

Do you have picture? Not good enough with plumbery vocabulary yet

If it put it in hot water, I can put it but I’m really wondering if a silicone one more flexible will be easier or not.

There are tons of styles, some have 90 degree bends, some are designed to glue to hard pipe, etc! — this one has American pipe threads (NPT)

Yes, heating it will help! Using some silicone grease lubricant on the inside of the soft hose will also let it slide onto to barbed fitting easier!

— just be sure to use a hose clamp around the hosing where it is stuck on the barbed fitting!

Those clamps are key, and I’d use two of them.

That’s how my tank is set up

Thank you!
Done! Hopefully, I had a silicone pipe, didn’t easy to put it.

Looks good, but replace the clamps as they will rust on you quickly and become a problem later.

I would use the plastic clamps, or worst case, zip ties

They are in Inox. LFS told me it was ok…
I had also one near the sump so it will be in the water.

Nice...hopefully 316 grade.

Inox (EU name for general stainless steel) comes in many grades, all of which are steel alloyed with chromium and several other metals…

Some grades of inox/stainless are more corrosion resistant than others (think, parts on a marine boat)… however, all Inox/stainless steel parts will leech heavy metals into a contained saltwater system!

— this is part of the reason marine aquarium pumps typically have a ceramic impeller shaft!

So.. need to change it!
But I’m looking at several website and I find no plastic clamps.

Ceramic impeller shaft?

Try “plastic hose clamp” as your search keywords, bulk reef supply does carry them, though I’m unsure about shipping internationally!

Ceramic impeller shaft?

Our pumps move water by spinning a part called an “impeller”! These impellers need a rigid shaft going through the center of them to spin around/stay aligned!

Many pumps use an Inox/stainless steel shaft, but marine specific pumps will typically have a ceramic shaft instead!

Sorry, bug below…
So I jut found Inox 364 (Marin grade), could be good?

Do I need to put one here too?



@UncommonSense You lost me with the ceramic impeller shaft

You need one where the hose attatches at both ends.
