Default Whirlpoolin pump

Will using a smaller diameter hose from the output of my march pump to the whirlpool valve increase the pressure?

I'm looking to improve my whirl pooling power

It will...but keep in mind the 809-HS will only generate a max pressure of 5psi when fully closed off....

I use 1/2" hose but have the end of the copper tube pinched a bit where is shoots back into the pot. Pinching the end makes it shoot a bit harder (like putting your thumb over the end of the garden hose) and makes the whirlpool stronger. Make sense?

Does this really help? I see how the restriction would increase the speed of the water coming out of your whirlpool arm, but at the cost of reducing the flow rate. I would have thought you'd get the best whirlpool by maximizing the amount of water going through the whirlpool arm, not it's speed.

I guess I'll have to play around with this...

It's sort of a momentum thing. Think about a really big tube. If you have 6gpm flowing from a 6" tube, you'll hardly have any velocity. The wort won't whirlpool faster than the velocity of the wort exiting the tube.

+1 on reducing the diameter only at the end...
I use a stainless hose barb. I think it's 1/4." If you go too small you could blow your silicone tubing.

That makes a lot of sense. Thanks! I'll give this a try.
