And how much water pressure do you have? I need to turn the hot and cold water on all the way to get good suction.
Insightful. How did you know??
I realized that I needed lots of water going through it so it was up all the way in my initial tests. But now that you mention it, this morning I was trying to get a shower and the water pressure was pitiful. The whole house carbon filter was clogged, I had to go down and turn it off to get decent pressure. I hadn't put two and two together until I read this. I bet that was a big part of my problem! I'll have to try it again.
$4.86 waterbed kit
$10 hose
$5 fitting for hose

Total cost: under $20
Total cost to buy (online with shipping, my only option cause they don't sell them here): around $60
So there you go. I'll save myself $40.
