It is hard on the pumps low pressure seals to have to pull water through all that hose and the fittings, not to mention up off of the van floor(in low water level situations). It causes cavitation on the pump head. Your pump will tolerate much higher temps or longer bypass time if the water is under pressure...or at least not under negative inlet pressure or suction.I have the suction side of my truckmount (Judson TNT) fresh water pump plumed to my 100 gal onboard water supply
No transfer pump, works great, Am i missing something?
No accumulator needed Jim. Yes I was a little sceptical about this having had Prochem's with the bladders for so many years but I decided to give it a shot. I really felt I needed something for my new set up truck mount/show truck. It has almost 30 foot of hose going from my fresh water tank to the pump which is up pretty high on the El D. Now I tried a pump from Northern first but it drained my battery. Johns/Mytee's pump has an intelligent circuit board that stops rapid recycling with a built in "soft start"/"soft stop" switch that is sweet. It stops over heating problems too. I also really like the built in filter. But most of all what I like most is the "high flow" capability. So far I love it. Tomorrow I am going to take it on a rat nasty upscale home (renters sub-let the house and thrashed it) and can't wait to see how it performs. I'll post back.Rob do you have a blue bladder to help shut off the pump so its doesn't run too much?
So true. The circuitry is so quiet it is weird because I'm used to the out dated loud ones with the bladders. This bad boy will really flow some water. I picked up a project box and installed a nice custom switch too. Looks sharp. When weather breaks I'll do a lil video for it.the circuitry is what make this pump better I worked for 20 years Installing auto security/stereos if you wire the pump to a relay with and on and off from your TM battery Ignition on only it will never drain the battery since it will only work with the TM running
Great Job Mytee.
Hey Rob, since you have this pump and have run it for a bit now, do you think this is a pump I could use with my Porty setup or would that pump be overkill for me? MY PLAN 75-100 gallon fresh water tank pump out to the M5 A/F, I leave the M5 on the van so it would be like 6 foot hose run to water tank.John's pumps have many features that others don't. We are working on a video that will be up soon.
There is already a lot of pumps out there that can Pull their own water. Cat makes several. The problem is people don't use the larger hoses and fittings like 3/4" so the suction level stays down. General makes a very common pump that will pull water from 13' below it.<br>Here's a novel idea.
A TM that doesn't need a transfer pump between the fresh tank and the pressure pump.
