Title: Running 2 pumps in tamden
Post by: williamx on June 25, 2004, 11:57:57 pm

What would happen if I was to connect one pump to the water container then run a hose to another pump about 100 feet away? and then cleaned the windows from that pump?

You would have two pumps pumping out the same rate ;D

Why would you want to do that?  To make sure it gets there ???

I think I understand what you mean from a post on another site.

You tried a long stretch of 10mm hose, but the pressure was low so you thought a booster pump at the other end might help.

The problem is that 10mm pipe is narrow and gives a high resistance to flow.  Thats ok when short distances are involved, but the longer the pipe the higher the resistance.

Use a standard garden hose (about 25mm) and you will find you can run more than 200 ft with no appreciable drop in pressure.  Connect youe pole with its smaller pipe at the end and it will work fine.

The best hose is "Tricoflex" as it doesnt kink so easily.  (But its also quite expensive)

Thanks for that Philip :)

Do you know where I can get some Tricoflex Hose? also the connectors to fit the 10mm hose to the 25mm hose?
