    Simpleguy68, you laid out some valid reasons why a vacuum tanker may not be right for your department. That is why regarding what type of apparatus you are looking at it is key to determine what works best for your department.

    As with any apparatus there are some give and takes as you indicated regarding length and cost. For other departments that can afford the length and additional cost they eliminate an engine for a fill site, free up personnel, make additional water sources available that were never before accessible and increase their water delivery.

    Regarding the water source being 100' from tanker access, the vacuum tankers don't really care about the length of the hard suction. Even with a 125' of hard suction they will out perform a 450 gpm floating pump through the same length of hose.

    I also noted that you aren't against the concept, just a vacuum tanker in your department. That's what these discussions are about. The exchange of ideas and information to help people determine what they need to look at and what they need for their department.

    The second paragraph is also a good point. I always wondered about that- even if your fill lines are supplied off a PDV equipped manifold, as soon as the gate valve for THAT outlet is closed, you're isolated from the dump valve.
    I do not know about 3 inch storz for sure but since it is a metric fitting I do know that 4 inch storz is barely over 3 1/2 inch actual opening. Also some of our AWG appliances the 2 1/2 valves are actually 2 inch flow.

    3 inch cam lock is 3 inch flow.

    We're surburban/ rural as well but we have a DECENT water main system(where we have it). Like I said,you could put two Vacs on it simutaniously loading and still have reserve,a couple end hydrants being excepted. We're looking to do a vac for speed/manpower requirements in the early stages of a incident. T.C.

    UPDATE. We have purchased a demo E-One watermaster 3500 gal. Looks like delivery within the week. Now the fun begins.

    It certainly SUCKS. It was outhauling the old one at the drill 2 to 1. Old-2000 gallons,NEW 3500 gallons. Still learning how to get max production from it but a great addition to our arsenal. My retirement 'home",hehe.

    T.C.

    Does it have a pump and if so what capacity and how is power provided?

    A while back we provided mutual aid to a department that has a semi tanker and the operator of our vacuum decided he wanted to try something. The department was rightly using their semi as a "on site" tank and letting smaller tankers keep it full. He and I have shared a lot of discussions over the years and although we may not always agree we are cut from the same thread. He decided to supply their semi tanker through LDH by putting pressure to our tanker. He said due to the low friction loss of LDH it worked great. Might be something you want to keep in the back of your mind.

    Take care,
    Walt

    Walt,You remember our ORIGINAL discussion? How my Boss was going to have Zero,Nix, nada firepumps on the Tanker? Well I pushed all I dared and still retain my job. I have a Gas powered 600GPM pump that shortly will be mounted to the truck in a fashion that I can connect a hose from the right side discharge to the pump inlet. Our tank only builds 12-15Psi. We've tried a few experiments with tank pressure only,nothing to date suits me. We took the Boss to a local Big Water Inc seminar,concluding tomorrow and guess what Mark Davis said? Turning out to be a pretty good week

    At todays drill we were loading at over 1000gpm didn't make a minutes difference if we used the vacumn pump or just conventionally loaded.About 3 minutes vacumn,3 and a halfish with 4" feeder. More tomorrow as we go into more advanced operations.

    I remember our conversation, primarily because "A Husker said so". I still stand by what I said.
    I know that you said hydrant vs. vacuum was only about 30 seconds (ish) difference with 4". 30 seconds on a shuttle makes a difference. Try 5" LDH and you will improve a little more. As we both know, fill and dump times are what can change a tanker shuttle and every little bit counts.

    Keep us updated.

    We did a Big Water drill in Casco last weekend.With a 2+ mile haul and a couple other tankers we were able to maintain 750+GPM,once we changed the Attack truck strainer we did over 1000gpm. And YES,our Tanker lapped a few of the others.Loading rates vary by which strainer you use but you are EASILY loading in excess of 1200 GPM. Still waiting on a few fittings to complete the rig,the package E-one sends you is OK but barely adequate for high performance results.Once the rig is lettered and the pump is put on,I'll post a couple more pics

    That joke is funny the first couple times you hear it. After the 50th,not so much.Rig is working well,I'll throw up a couple more pics tomorrow. Still waiting on the pump enclosure and a couple more fittings to finish it up.

    Looks great! We just upgraded our tanker from a 45 year old chassis to a 10 year old chassis, way safer and way more efficient!

    Wait...I thought YOU were the boss? Tell him it's nothing but an overgrown cop car without a proper firetruck si-reen.
