How-Test MCP655 Swiftech Pump

[ibmkg]

I just got this pump. The problem is that I am not able to test it since it does not suck up water. Manual says that it needs to be primed.

So what I did is took a 3 inch length pipe and used it for the inlet. This pipe was placed directly under a flowing tap. A long 4 feet pipe was used at the outlet.

Now with this setup the water circulated but the thing is that I had to be careful about pipe directions i.e. if the outlet pipe was 90 to the inlet (parallel to outlet) no flow takes place. I have to bend it. And not too bend it since the flow would stop. This is a pain , what is the proper way to do it?

Also, I don't see a huge flow (317 at 3.5 bar should have been 5 times at least, the current I am seeing).

fill up a bath tub or sink full of water instead of using running tap. The sink is easier and faster but you have to aim the oulet down into the adjacent sink so it doesn't spray the whole kitchen.

You can also fill the pump from outlet, run a 7-8 inch tubing from inlet and fill it up full with water, and loop it back to inlet quickly.

Thanks for replying.

What I did is took a bowl and filled it up with water. Filled the inlet with water too. Then placed this inlet tube in the bowl. However, as soon as the water in inlet tube is exhausted, flow stops and it does not suck water from bowl. Perhaps it needs to be continuously fed yet I cannot submerge the pump in bowl.

I can make a loop i.e. fill inlet with water and connect it to outlet but my aim is to verify 317GPH. i.e. There should be some way so that I can see the water while it’s flowing (outside the tubing), check it's pressure and take a gallon and verify the time required to fill it.
