Very helpful thanks bud! Gotta quick quesion. I've gotta Honda GX200 engine with AR pump rated at 3.0GPM 2700PSI. I wash cars and thinking of upgrading to the 3.5GPM 2500PSI AR pump which is about 700-800 more cleaning units. Will that make a big enough difference do you think to increase my cleaning time? thanks!
When washing, in particular soft wash which is what you are really doing, less pressure and more water is better. I use the example of a spray bottle and garden hose. Spray bottle gives more pressure and less water volume. Garden hose gives less pressure bit more volume. Which would you rather use to wash a car?
Be careful as more GPM usually means more power needed from the engine….Almost every machine giving you more than 3 GPM usually have a 240 or 270 engine but I would like Brian to confirm if the 200 has the guts to move more than 2.5-3.0 GPM.
Good morning Brian, in your video last year about rebuilding pressure washer washers (great video) you said that if you have water in the oil it might be more financially feasible to just buy a new pump. I've looked on Amazon for an AR like I have and the seller is Tool Barn. The reviews are really bad or really good, nothing in between. Do you have a supplier that you recommend?
You can purchase replacement pumps from most Sherwin William's stores. You can order online from a supplier called Watercannon.com if you buy in person, warranty issues are easier to deal with later.
Great video I have a question I just purchased a Honda GX 390 motor and I also purchased a 4000psi 4GPM GP pump., I just put the pump in the motor yesterday but I have no pressure I have a really good water flow but no pressure, Do you by chance I know what is causing this?
Make sure the unloader is turned clockwise. Also check the nut under the black cap on the unloader, it should be adjusted close to the bottom of the unloader.
Did you figure out your no pressure? You have a great pump with the general and a great motor to run it! Did you purchase the motor and pump new or used?
Hey Brian quick question I have Honda gx270 with AAA pump 4K psi 3.5gpm and I want to replace it with AR VIPER HEAVY DUTY FULLY PLUMBED 4 GPM 4200 PSI are those pumps any good and is this to much for my Honda gx270. Was thinking to run it around 4K 4gpm
@@Brian_the_repair_guy hey Brian it’s me again. I need help getting a pump for my pressure washer. Is there an email I can have to email you some ideas I have in mind if that’s okay with you
Also once you jump up to 4000psi/4.0gpm the engine power required to operate the pump increases so technically for those specs you should be running a 11-13hp engine. The 9hp Honda gx270 I have was the same 3000psi/3.0gpm I bought used. When that pump quit I had 4 other Honda gx340/390 machines with various pumps and back ups I decided to put on a general pump at 3500psi/4gpm I had sitting on the shelf and once I got the unloader set and the right tip on the gun it worked great but the 9hp Honda seemed like it was struggling a bit and running louder than before with the smaller pump. It ran a whole season like that but ended up wearing out the oil seal on the motor around the output shaft that the pump slides onto. I thought no big deal it's probably from wear and tear and it old so I replaced the seal and again in a few months it was leaking again. I am guessing it wore out from excessive heat around the crankshaft mixed with crazy vibration?!?!? Decided to put the pump back on a larger gx340/390 and no problems since. Also I put a smaller pump back on the gx270 and no leaks so make sure your engine meets the minimum horsepower needed to operate the pump. Just because the engine is a 1 inch shaft doesn't mean it will run all 1 inch shaft pumps. I also have 17 years experience running, fixing, and maintaining all my machines from bigger belt drives to gearbox drives to the basic direct drives! Pressure washing is awesome!⛲💦🔫👍
I would have to disagree. An 11 or 13 hp is not necessary. Many companies produce a 9hp 4000psi 4gpm machines. Simpson, Powershot and Hustler come to mind and they produce a washer with the GX270 as well as 4gpm 4000 psi. You are right about the engine. If there is too much stress, the sound of the engine will tell you. This particular customer has had me replace the pumps on all his machines to 4Kpsi and 4gpm over the years. No issues on the engine. Still running strong. After 32 years of doing this, I have no issue stating it can be done with little concern on a ln engine in good working order. If your experiencing vibration on yours, there is an issue. Regardless of the pump or the engine, there should be no excessive vibration. Good luck
BRIAN---FOR A HONDA GX200, 6.5HP, , WHAT IS THE LARGEST PUMP I SHOULD TRY TO USE-- WANT TO CLEAN UP OIL STAINS ON DRIVEWAY IF POSSIBLE---BY THE WAY - USED DIESEL OIL STAINS, MAYBE THE WORST THERE IS
@@Brian_the_repair_guy I have used over 20 different chemicals to try to get it out of the driveway. Torches, gasoline, Dawn, Get it up, muriatic acid, etc. Anything that has been suggested on youtube i have tried i think lol. So, if you would, what is the biggest pump you would put on a GX200, 6.5 hp---I have a 2.5gpm-3600psi currently..
The more powerful the machine the farther away you can spray from the substrate while still maintaining efficient pressure to clean, thus you can cover a wider area. Weaker machine and you have to get closer in and the closer in and your spray pattern becomes narrower.
True. The advantage of the "weaker" machine is it is less likely to damage the substrate. They also require far less water volume to operate properly. I reccomend guys have a heavy duty machine and a cheap machine to cover each situation.
@@Brian_the_repair_guy instead of having two machines, couldn't you just turn down the pressure on the bigger machine to the level of the 3000psi machine when not so much is needed?
Yes. At is a good manufacturer of pressure pumps. They have 2 classes. One is manufactured in Italy, the other class is manufactured in China based on AR specs.
Hi Bryan, if you have to choose between these 2 machines which one you'd take for small just starting pressure washer business cleaning driveways and surface preparation for painting. 4000 PSI @ 4 GPM 3500 PSI @ 4.5 GPM Thanks in advance!
This is a hard question to answer. The total setup will make a difference. Short answer, I like high gpm over high pressure. Long story is if the pumps are the same make and manufacturer then you can adjust the unloader to increase the pressure to 4,000 on the 4.5gpm. Depending on your water source, you may be better with the 4gpm. Some houses struggle to give you enough water.
If you are starting a pressure washing business and have a choice the 3500psi 4.5gpm is the better machine. The more GPM the better. If you are worried about the water source then you can use a 30 to 50 gallon water tank as a buffer tank. youtube has allot of videos on how to set up the buffer tank.
@@Brian_the_repair_guy No it's not. If you are starting a pressure washing business and have a choice the 3500psi 4.5gpm is the better machine. The more GPM the better. If you are worried about the water source then he can use a 30 to 50 gallon water tank as a buffer tank.
@@zoukiezouk2278 thanks for the input but you missed the point of my comment completely. As I stated, GPM is best and you can INCREASE the pressure on the unloader to get 4K psi on the 4.5gpm pump. This gives you more CU than the 4k at 4gpm or the 3500k on 4.5 gpm. If someone is concerned about their gpm delivery from the source, then a machine that requires less gpm would be a better choice. Not everyone has the ability to haul extra water. The simple solution is a second machine that uses less gpm. Thanks for you comment. It gave me a chance to further explain the pros and cons.
@@chriscoerper4489 first thing I would check is the pressure. If you have a gauge, then make sure the machine is not producing more pressure that it is suppose to be set for. If the pressure is too high, that can happen. Check the oil in the pump first. Make sure the level is good. If you don't have a gauge., turn the pressure down three turns and see if there is a change. Keep me informed please.
@@Brian_the_repair_guy I have a gauge and it has the correct pressure with not much unloader spike. Oil level is good in pump. Do you think pump at 4.7 GPM is too much for the 270? Thanks
@@chriscoerper4489 is this not the pump that came on the machine? If this is a pump that was installed outside the manufacturer, then yes. The 270 may not be able to handle that much water under that much pressure. You can try turning the pressure down to 3000psi and see if there is an improvement.
I have just aquired a landa pressure washer. It has no unloader valve that I can find. Instead it has a pulsation dampener. It is not building enough pressure. It builds then you squeeze trigger it releases without building. If you release trigger it builds again for a min or two then the motor shuts off.
@@davidgrossmiller7073 this is an older pump. The parts are limited. If you can locate an owners manual, there will be a list of the parts you will need to rebuild the pressure dampener.
@@Brian_the_repair_guy Since this is an old pump and pulsation reducer. What would you suggest it replace these parts with. I can not find any info on birdwell inc. pulsation reducer.
