Before screwing down the subfloor once and for all, I decided to run a final test on the water system to see it perform while pumping water. This I did for several reasons:
- I had a nagging doubt about my gerry-rigged outflow connection.
- It was important to see if the Shurflo pump (4008-101-E65) worked as promised.
- I wanted to see how the tank system, connected in series, could keep up with the demands of the 3 gallon per minute pump.
So I did this by refilling the system to 1/3 capacity (roughly 21 gallons) with a new water jug slepped multiple times to the spigot on the adjacent property. I then hooked up the pump to the outbound hose and powered it up with the twelve volt adapter borrowed from the mini-fridge/cooler (purchased last month to keep my food stash cold. Very handy, BTW). Thank God I did this test because the outbound connection affixed to the tank failed miserably.
Originally, I could not find a connection that actually fit the strange nipple protruding from the tank, so my connection was improvised using a small section of 1″ PVC, split tubing as a gasket and black PVC glue. BAD idea. The minute I turned on the pump, water came spewing from this hokey connection, soaking the fiberglass insulation which, by the way, makes an effective sponge. Oooops. So, to avoid my folly please observe the photo lower right. This stock pic illustrates the proper way to outfit your tank. Specifically, the green ribbed 1″ hose affixed to the large nipple with silicone cement and a clamp should be the fill hose and the smaller 3/8″ connection should be the outflow. Well I reversed this config. and, not wanting to pull the tanks, I simply adapted by using a PVC compression fitting, a reducing connector and a 1/2″ elbow (pictured lower right). Whew, talk about a work-around. For those of you whose eyes have not glazed over, just pay attention and hook up the tanks as intended and spare yourself 8 trips to Home-Depot trying to get it right.
Well, all’s well that ends well and my trips to the well, well, they were rewarded with a nice, leak-proof flow and my first load of dishwashing was officially recorded. Amen.
