Nice job on the Class, Kent. The attached article shows a little different slant on manifolds. It features Rumson, New Jersey's new manifold truck. It's not a mini-pumper - it has no pump or tank. It's a 2000 gpm "manifold on wheels" that carries its own dual bed of 5-inch hose, master stream devices, attack lines, 10kw generator and tools. Rumson has areas with limited access for larger vehicles including large homes with long narrow driveways, and bridges and boardwalk with weight…

Thanks for the clarification Brad. I think this is a case of regional terminology. Locally, correct or not, a 4 way valve and mainifold are two different appliances with two distinct uses. Hence my "confusion" post. I was confused.<br />
<br />
I have zero experience with tender operations and most of our supply lays are pretty short (300'-400'). I have never seen a Humat valve used in the middle of a lay, only at the hydrant - but I am sure it works. Neither have I had occasion to pump "into" our version…

I have zero experience with tender operations and most of our supply lays are pretty short (300'-400'). I have never seen a Humat valve used in the middle of a lay, only at the hydrant - but I am sure it works. Neither have I had occasion to pump "into" our version of a manifold. While it would certainly work, we use it primarily for supplying attack lines off a reverse lay (LDH inlet to 2 1/2" outlets).<br />
<br />
That is the nice thing about the forums: Learn something new everyday and it is all interesting.<br />
<br />
Thanks,<br />

Not sure who is confused, at least not me. The humat is just another type of manifold with a different purpose. I have a lot of time with LDH manifolds and the one Mark is referring to is just simply a giant gated wye and could have two 2.5" ports or four and may even have the 5" port going all the way through with guages to look at line pressure to ensure the manifold is not under to much pressure to cause catastrophic failure like the one in NJ. They are great for tanker shuttle operations at…

They are great for tanker shuttle operations at the fill site, or can be used in a revese lay or even reversed to flow four 3" lines into it to fill the 5" supply line.<br />

I'm sure you all know that but someone else who reads this may not.<br />

I think we are confusing two different things here.<br />
<br />
A manifold (in this part of the world anyway) is a large gated wye for reducing an LDH line into 2 or more smaller lines.<br />
<br />
A device for boosting pressure on a forward lay would be a four way valve, of which Humat is a brand name.<br />
<br />
Maybe different parts of the country have differing terminology?<br />
