Like your boss’s boss, I would.
If you just want to throw $450 away I’ll send you my address and you can mail it to me and I’ll hold onto it until you come back to your senses. AR pumps are…not good.
Ah, I didn’t read back enough. You’re talking about a sacrificial pump. In that case, yes, buy an AR lol
Haha, I was going suggest calling it ‘spiking the punch bowl’. I guess I shouldn’t be too surprised to hear it has come up before around here.
Why in the world would you want that for doing a roof. If we’re right and may have to replace the pump every year or so, the GP one is $355. We go from talking about a roof pump to you wanting to do surface cleaning, lol.
Haha, I realize it’s reaching deep into the rabbit hole but if we’re going to break the rules, may as well break them properly. I don’t clean that many roofs but that kind of gpm would sure put more of them in reach & make light work of them. It seems like a few minutes of SH followed by downstreaming a house & cleaning a driveway would rinse the guts out well. One hose that absolutely rocks for every situation from the roof to the curb sounds tempting to try. It’s definitely within reach. Only point of contention is how long it will last. Maybe I’ll toast a pump for research purposes.

Just for future reference, you can build that exact same box for about $25 and 10 minutes of your time. The boxes are cheap on Amazon and so are the fans and the switch. Probably have as much in wire and connections as the rest of it. I get it though, time is money and plug and play is nice.

For $100 they could have at least bolted the bracket on straight
Thats a PC case fan. The cheap chinese ones are worthless. You can get them in various sizes and ones that run at different speeds if that one fails, and you can daisy chain a couple if heat is an issue (push pull is the optimal setup with hot air direction going up and out if possible). Noctuas are supposedly the best, but I am running about 11 artics in my supersized ATX phanteks case. Artics are a lot cheaper. I don’t like radiators in PCs, one leak and poof, there goes a $1400 gpu.

I wouldnt mind seeing heat shrink on those crimps. Other than that it looks like it will serve you well
@DisplacedTexan - you mentioned a few times you replace the electronic pump relays with external relays like the ones used on automobiles. What issues were you seeing? I noticed you mentioned that this creates a stable 12v system for you. I’m about to do the same and wanted to confirm.
Well, technically it’s a solenoid not a relay. The factory relays on some 12v pumps don’t seem to last very long due to heat and the amount of cycles they see. When you install a solenoid you effectively bypass the factory relay. The automotive solenoids can withstand thousands of cycles. No issues with trashing relays since I’ve been using the solenoids. If you’re not having issues with the factory relays then you may not need a solenoid.
100PSI makes a huge difference when you want to get distance. Just make sure you’re washing it out well after running SH through it.
Right - solenoid - trying to type less
Yes - factory relays are crap. I keep a few on hand , but gonna move to the solenoid.
Which pump are you running?
Delavan 7gpm/100 psi
