Return Plumbing Question

[italquam]

I am looking for some advice......

My sump has 3/4'' Return outlet, which i was thinking of adding a coupler onto it to go from 3/4'' to 1 '' for my return plumbing since i have a lot of 1'' return parts.

Does anyone know if this will make a big difference on my return or should i just order all 3/4'' parts?

My return pump is a Ecotech Vectra M1......FYI

you cant reduce the water in front of the pump. but you can In large it on the exit side of the pump that much for sure..

if the inlet of the pump is 1 inch you cant have 3/4 pipe going into it as a example.. If the pumps inlet is 1 inch you can have 1 1/2 going into it..

Hope this helps.. Of COURSE there are sometimes exceptions..

So the input I am leaving alone, the output is 3/4 inch and i want to enlarge to 1 inch so i should be fine then....... did you mean to say outlet on the second part of the above answer, i was a little confused because you mention inlet both times...

thanks for helping out

I actually just got an answer from Ecotech on it, they said it is fine to go up one the plumbing size for the outlet......

Vincent,

Thank you for contacting EcoTech Marine. It wouldn't be an issue at all to increase your diameter to 1 inch PVC. If you have any other questions, please don't hesitate to reach out.

Thanks again,
Alex

I see you get the answer right from them.. but nope i was saying you can increase the inlet of the pump with no issues at all. the Outlet you can increase as well but only so much depending the pump....

was pointing out you cant decrease the input...

sorry for confusion:rollface:

Ok now i undertsand, i appreciate the help. Thanks

Absolutely go up on the return plumbing, it can make a huge difference in the output of the pump.

Obviously you don't need to go overboard but going from 3/4 to 1" will make a difference depending on how the plumbing will go ie up to a T then across to two returns in the tank that go up through the overflow and back to the tank. I'd probably go even bigger than 1" from the pump for as much as you can. Larger pipe is a cheap way to increase flow efficiency.

For example, i am going up from a Vectra M1 which has 3/4'' output to 1'' inch 45 degree elbow then up to 1 inch PVC to a 1 inch return penductor eductor. My plumbing is over the back of aquarium as my tank has no built in plumbing. I will be using a reverse check valve as a safety if power goes out or i shut pump off. Same check valve setup that is used on Melev's reef tank on his website.

With that few restrictions going to 1" is great and may be all you need. Depending on how much experimentation you want to do it would be interesting to see the power settings on the pump to get the same flow with 3/4 vs 1" plumbing.

Well i will probably have 2 - 90 degree elbows also in plumbing in order to get over back of the tank.

That would be a great experiment........i would be curious as well
