Dry Fire Hydrant Design #14 - Patriots Point Museum - South Carolina

Deputy Chief Matt Cole (Chichester FD - New Hampshire) was kind enough to provide us a few photos of an interesting dry fire installation in Mount Pleasant, South Carolina at the home of the Patriots Point Museum. While we have no official details of the installation regarding when, why, what, and how...one can surmise quite a bit by just looking at it.

The design includes the use of a single length of lightweight, 6-inch suction hose - looks to be perhaps 20-feet or more in length. A Zico floating strainer is attached to the suction hose - from our September 2017 suction strainer flow tests, we know that the Zizo strainer performed quite well (but at a lift <5 ft). It appears that some type of cable lowering/retrieving system is used to deploy the suction hose and strainer onto the water's surface.

We would like to see some performance test data before placing any serous judgement on the design...however, a couple of concerns include the constant exposure of the lightweight suction hose to UV rays and the long-term effects of the load placed on the couplings of the lightweight suction hose when the hose is in the stowed position.

Otherwise, we always enjoy seeing creativity. Many thanks to our good friend DC Cole for taking the time to take and send us the photos.

What is the lift at mean low water?

We don't have that answer. All we know is what we see in the photos. Although, at best....the lift looks to be greater than 10-ft at high tide ...using the water marks on the support structures.

We had some suction hose (made by Firequip - actually a nice, VERY flexible hose) that was mounted on the top of the truck. After ~ 10 years of exposure to the variable New England sunshine, the exterior of the hose was very tacky, even leaving an almost pine pitch type residue on your hands if you handled the hose.
