Dave - If it's any help, I consulted with the chief engineer at Tasco to select my pump. I'm using 250 feet of 1/2 inch pex to heat a greehouse. He recommended the Tasco 009 which can service 35 ft of head. Yours sounds like it will take a much larger pump with more head. Another option he...

Dave - Which position is "open" on your valves? Is it completely "unscrewed" or completely "screwed down"? Also, have you tried adjusting your flow meters by unscrewing them a bit? When I do that, the flow increases, so they actually act not just as a meter, but also as a valve. It's worth a try.

Dave - I've had the same experience. It's the same with Pex Universe and Pex Supply. When I bought the manifold from Pex Universe it arrived without the compression fittings. After three weeks trying to reach them, I finally got someone who said they'd be shipped right out. Two weeks later when...

Dave - Have you gotten any help on your manifold balancing problem? I can't find any replies to it and I'm having exactly the same problem, except that I can't figure how how to use the return side valves and the supply side flow meters together to improve flow as the Everhot site suggests you can.

I just installed an Everhot Pex manifold that's supplying a 250 ft loop heating the floor of my greenhouse. We're having trouble getting a good flow through the manifold, although when we disconnect the supply line, the flow is pretty good. The everhot site mentions that flow and balancing can...
