I completed my first two jobs this week! One was just a drive/walk way but the other was a full on driveway, roof, deck, koi pond, & house wash! Yaayy, the rent is paid!
I’m having trouble with my Gen III softwash pump though. When I went to start my second job the first pump didn’t switch on. The on/off switch wouldn’t even flip. So I switched over to the second built in pump and quickly moved on to the job, exactly why I bought this machine in particular. I have used the machine less than a dozen times but never had any issues while practicing and have made sure to flush the lines with water. I did notice some discoloration in my line near the brass valve I put in for the flush on the sh line so I have ordered proper pvc 3way valves with fkm seals to replace asap. Could this have messed with my pump so quickly though?
I also noticed that my pump seemed to be pretty loud towards the end of the job. Is it starving? Does this indicate an air/pressure leak?
I am not getting the ideal performance out of my machine in my opinion, it couldn’t reach the roof peak from ladder or on the ground. I’m going to have to retouch the roof wash but didn’t feel safe climbing on it after I had already started washing (Client was happy with the job, but I’m not). But I’m hoping this is all user error, praying I haven’t fried my pumps before I’ve made any money.
(For those concerned about the koi, I did my research and was very careful To super rinse everything but also we removed the fish to an aerated tank temporarily and pumped out the waste water.)
Pump sounds shot. No pressure, how long have you owned it? Call power wash store if you just bought recently let them know. I’ve had gen 2 for 2 seasons and have had no issues with it. I would change out the three way like you said. If it was me I would take the 90 degree off the end of the proportioner and use a straight barb instead. I think it will help the flow a bit.
I got it in August but fired it up for the first time just 2-3 weeks ago. I called the Power Wash Store and they thought I should test the switch by connecting the wires to the other switch or just see if the pump responds when hooked up directly to the battery so I am trying that. As for the other pump I’m sending a video to them but it’s possibly just air in the system. We’ll see. You’re absolutely right about the barb and I just switched it out! Thank you for noticing that.
You’re welcome. When you find out the problem, post it if you could. I’d be interested to know, hopefully it works out for you. 12v can be finicky to deal with from time to time.
That sounds sounds like the pump is loose or vibrating, also make sure you have the pressure switch adjusted for the proper flow rate with your tips if you want max performance,
Here’s a video on how to do that Pump PSI sweet spot - YouTube
As for the switch I’d recommend getting A marine grade switch if it’s gonna be getting wet, those autozone ones have always burnt out on me
Thanks man, I tested it and I’m relieved it was just the switch. I was kind of panicking it was gonna be the pump. I’ve ordered one of those switches, seems like your definitely right about those ones getting wet.
I hadn’t seen that video about adjusting the pressure switch, thank you for sharing that’s extremely helpful. That guys videos are great I should probably just try to watch them all
I dunno man, I’ve had the fat boy 7gpm from Bob and it’s going on 2 years with no issues. If you’re rinsing the pump thoroughly after each job, you should get a minimum of 6 months- year. Maybe I’ve just been lucky though
They’ll regularly fail if they’re choked or not rinsed properly, there’s nothing inherently wrong with the design of a 12v pump, open one up next time and study what failed, it’s either corroded or burnt out or both. 5 gallons of water isn’t enough to rinse a 12v pump like many suggest on Facebook and YouTube, that’s silly talk, let it cycle for 5-10 minutes while your doing something else. You cant over rinse it.
I have a question. I just set up my 7gm pump with a DYI proportionor. Im using 1/2 GF valves. It seems that there is a low flow of water that comes out of the metering valve. I’m using 3/4in hose in and out of the metering valve and pump to the reel. The hose coming from my buffer tank is full of water, but when it comes out, it’s less water. It’s seems that the water flow can’t keep up with pump. When I pull Trigger on gun, air is always coming out. Can anyone give me any advice on how to resolve this? I don’t want to burn out a new pump
@Magicmike Post a picture of your set up. The first thing I’d check is if there is any possible air leak at any of the connections. If the air isn’t leaking in anywhere and it’s air tight, then it must not be getting enough water to the pump, like you said. Do you have your lines hard plumed into your tanks?
Go thru each of your inputs and make sure you’re not getting any air. Cut off the other 2 and cycle thru each one. You’ve got a leak somewhere. To test, I always keep a short - like 10’ clear hose that I can plug in right after pump to check for bubbles, also to use for transfer hose.
