I run water from a bucket to the wheels and back again with a submersible pond pump.  Today I joined together the plumbing on 2 machines and now the pump I have is struggling with the extra length. 



Simple fix would be to raise the bucket but I also figured a new pump may just be good to have all around.  Right now it's a normal table height but I'm not sure what kind of pumps people are using for this since it runs into grit sometimes (I do basic gravity filtering but it's not perfect). 


Also, the knobs on the cabbers to control the water to the wheels leak.  I've caulked around them but it actually leaks from where the T goes into the housing.  Anyone know better hardware that's not leaky?

Looks like a compression fitting. Shouldn't leak. Replace the brass compression thing, don't over-tighten and if its leaking on the threads try a little teflon tape.

I use the larger submersible pump from Home Depot ($54) I believe I paid for it. I have the same pump at both the Wisconsin and Arizona location. Have had one for 3 years the other 1 year. I pump from outside into my shop and up to 6 different machines. I have a master control valve that I set for what I would want for max water and then use the individual valvea at each machine.I use 1/4 inch tubing from the pump to all machines. I have the pump pluged into a plug with a switch onit, the pump pluggedinto one plug and a light into the other plug.If the light is on pump running,light off pump off. Seems to work great for me.

Right now I'm using a pump from an evaporative cooler, it's not submersible but it sure moves a lot of water and doesn't seem to mind the sludge. I also use the hose fittings from a garden irrigation system. Those barbed fitting don't seem to leak at all. Now if I could just that danged cheap tile saw to not make me feel like a drowned pocket gopher.
