I bough my sprayer a month ago and have had nothing but trouble with the power cord for the pump. Finally got that fixed, turned it on and no pressure to the pump! I almost returned it I was so frustrated. But watched your video and sure enough i just needes to turn that valve on! Super easy and it's working great! Thanks for the video!

[@chatkat9765]

Very helpful for my 40 gal. Sprayer, Thank you and stay healthy

[@larrycave7136]

Your video was very helpful I just purchased one ..the 20 gallon and it was a very nice intro to the product hopefully everything goes well

[@biffdotorg]

The best part was realizing how to clean the strainer even after I had mixed 30 gallons of chemical. Thank you!

[@AgriSupplyCo]

So glad you found the video useful Biffdotorg! Thanks for checking our the Agri Supply channel.

[@unoduney]

Thanks for this very informative video of this Fimco Sprayer. I have a 25 gallon Fimco Sprayer that I've had for 12 years and I was having an issue with keeping my desired pressing while spraying. I noticed I had to flip the power switch to off and wait while and then cut it back on to activate the spray. After watching your video I will go back and troubleshoot what is causing this problem. Thanks again.

[@AgriSupplyCo]

Hi there Unoduney, thanks for your comment! Happy to help and glad our video was useful to you. Feel free to reach out anytime to our Customer Care Center if you need any other help with the Fimco sprayer, have a nice day! www.agrisupply.com/contactus.aspx

My issue is the pump works fine but it looses it prime and I have to remove suction tube and fill with garden in pump while pushing in suction line to make it work

[@paulsscooter]

THANK YOU, Hi, I worked on my sprayer most of the day yesterday and wasn't able to fix it. I took apart the pump, replace the sprayer heads and the little filters in them and no luck. I looked on line and found your video, you said to remove the hose coming from the bottom of the tank and check the screen filter. First thing this morning i went out to the sprayer and check the screen, it was severely blocked. I took it out and cleaned it and put it back in, IT WORKED GREAT. Thank you for taking the time to make this video, I really appreciate it. Paul P.S.,,,,, did i say thank you?

[@PFHabitat]

My 3 nozzle boom less boom won't spray out of all 3 sprayer ports at the same time. It will only spray out of two. None of the nozzles are plugged because it's random which two it will spray out of when you turn it on, but all 3 will spray chemical, just not all 3 at the same time. Any thoughts? We've tried a 2.4 and 4.5 gpm motor on it and had the same issue

[@AgriSupplyCo]

So glad you enjoyed the sprayer video Mike! Thanks for watching.

[@mikethimm660]

I have been frustrated with this the past few years and figured out the solution. Modify the sprayer to make it a constantly flooded pump so the pump has a gravity feed from the tank and it works! I think Fimco wants to sell check valves and that's why they manufacture them with pumps mounted higher on the tanks

[@AgriSupplyCo]

Appreciate your comment Mikethimm660. Thanks for watching!

[@lindasuti1610]

Thank you for this video! Have you ever seen a situation where the solution was coming out of the pressure gauge and no pressure was getting to the wand? Is is just the pressure gauge I need to replace? Thank you.

[@budmiller725]

Hi Linda! Thanks for your inquiry. You may need to simply add one wrap of thread tape and retighten the gauge. Although, its not uncommon for a gauge to develop a crack and need to be replaced.

[@lindasuti1610]

@@budmiller725 thank you very much!

[@donens9310]

Great info. I have this same sprayer, but lately, the pump won't self prime. Advice. Also, is the total system meant to work as a closed system so the tank pressurizes and as such any loose fitting will result in loss of pressure?

[@AgriSupplyCo]

Hello Don, Thanks for reaching out! First, the system is not closed as the tank does not pressurize. Below is a quick list of things to check for on your sprayer. One of these could be the culprit, so we suggest the following: - Check for any air leaks in the supply line, including the rubber washer by the strainer screen - Make sure the strainer is clean as even sometimes a film will build over and could be difficult to detect with the eye - Check for cracks in the pump housing as something could have hit the pump or possibly cracked a bit over the winter - Make sure the suction outlet area at the bottom of the tank is free of debris - Check for debris in the check valve assembly by carefully removing the pump head to inspect - Check for a faulty check valve If you have any other issues with your sprayer setup, feel free to reach out to our Customer Care Team at 1800-345-0169. We'd be glad to help you troubleshoot things a little more in depth, thanks! Have a great day.

[@DEDBRD-di4yj]

Make sure you clean the filter in the tank . Generic roundup is notorious for leaving this thin film and causing you pump to clog up. If you had 180psi on a small wand theres no way you could tell how much chemical your putting out . You would probably be applying 3/4 times what you need .

Hi there F150, Thanks for reaching out! We would say it depends on the type of Fimco pump you are looking at and the application.

Hi there Doug, thanks for your comment & reaching out to us today! Let me consult with our technicians to see if we can come up with some suggestions for your sprayer issue. Will send you a message back shortly!

[@AgriSupplyCo]

Appreciate your patience Doug! Our suggestion would be to #1 Check the boom valve if you haven't already done so. Sounds like you may be having a problem with the manifold not opening properly. #2 You may need to check (if you have a boom-less sprayer setup) that the nozzle body is currently set in the "off" position. We'd be happy to help troubleshoot this with you more Mr. Doug if that doesn't solve your issue. Feel free to reach out directly to our Customer Care team at 1-800-345-0169 or www.agrisupply.com.

[@AgriSupplyCo]

Hi there Marshall! Appreciate you reaching out with your question on the Fimco sprayer. If you don't mind us conversing with our Quality Control Team, we will get back to you shortly with some suggestions for this. Thank You.

[@AgriSupplyCo]

Appreciate your patience! The first thing we would recommend is checking the screen in the suction hose to ensure it is clean & not blocked. It sounds like it is getting enough flow to build pressure when not spraying - But as soon as the valve is opened on the wand, there is a burst from the built-up pressure, and then the pump starves for water. If this doesn't fix the problem for you Marshall, please give our team a quick call at 1-800-345-0169. We'd be happy to help troubleshoot with you to figure out what the problem might be with your sprayer. Thanks, have a nice day!

[@miketyler7616]

Here's a question I didn't see. Mine builds pressure, and as soon as I open the boom valve, it's sprays, but the pressure drops to 0. It still sprays, but why does it go to zero?. Shouldn't it hold some kind of pressure?. All screens are clean and I just put a new manifold on it. Thanks for any help

[@masonmalone9961]

My sprayer wont build pressure with the boom line open only builds with both closed

[@AgriSupplyCo]

Hello there! Thanks for your comment. With the boom valve completely open it is not going to build full pressure. With the boom on it is going to build at the most about 35 to 40 psi. If it loses all pressure when the boom valve is open, it could be the inlet screen is partially clogged. How to clean that screen is mentioned here in our troubleshooting video. If the screen is NOT clogged it could possibly be a pump issue.

We'd be happy to help you troubleshoot some possible solutions if needed! Feel free to reach out to our Customer Care Team at 800.345.0169 or email us directly at [e-mail]. Thanks, have a great day.

[@AgriSupplyCo]

Hello again Tom, thanks for your patience! So it sounds like your bypass/recirculation valve is open to some degree. This would be the valve on the manifold that has the rigid tube that runs into the top of your tank. This valve allows you to adjust pressure and mix the contents within your tank. Here's what we recommend you try: 1. make sure you have no external leaks 2. make sure the valve (small gray switch) is completely closed 3. if this is not the issue, it has to be an internal problem with the diaphragm leaking inside or a nozzle issue Hope this is helpful, but please don't hesitate to reach out to us if you need more help troubleshooting your sprayer. Have a great day! www.agrisupply.com

[@iAvi8]

Can you clean them out with vinegar?

[@AgriSupplyCo]

Appreciate your question iAvi8! So we would actually recommend that you use a designated tank cleaner instead of vinegar. Cleaning out a sprayer with vinegar can damage interior parts and be corrosive. We recommend either one of these products for flushing out your sprayer.

I agree, they are junk. both tubes flat in six month, 3 of the four pump mounting tabs cracked off withn the second year. today,18 months, pump will not prime. I guess i will blow 70$ for a replacement pump as i do not have time to order parts and trouble shoot.

[@tempgar]

I have to replace my pumps about every 2-1/2 years. Purchased / Delivered Aug 2015. I spray 60 gallons of spray in March, May, July, and maybe Sept, across my property; driveway and woods areas each year. l clean it, just like I do all my equipment - thoroughly, with sprayer cleaner exactly according to directions. New pump in spring of 2017; now on 3rd pump. Manifold connectors just break - not even being touched. Just the jiggling of the pump running and the ride across fairly smooth property. If I knew another company that made a sprayer that could do what this one does and was more reliable, I'd through this one away and switch in a minute.

If you have a moment, please reach out to our team via email at [e-mail]. I will also speak to our team to see what suggestions they might have for this and send a comment back here on KZbin, thank you!

[@AgriSupplyCo]

Hello Richard, Thanks for your patience! Got a little more insight on your issue. It could be one of two things: #1- One possible problem would be on the suction side of the pump. Often times if the strainer at the cut-off valve to the tank is checked, it may be partially stopped up. It could be grains of sand or small pieces of other foreign material. Also looking inside the tank at the outlet point, it could be a piece of plastic of sort that has covered or partially covered the hole causing the pump to starve for water. It's also good to insure that the suction hose is clear all the way to the pump. The suction hose can be un-hooked at each end and safely washed out to insure that it is free of debris. #2- Another issue could be there is a small leak somewhere on the outlet side of the pump. This means that when the pump comes on to build up pressure, it then cuts off when the pressure is met. If even just a few small drops of fluid leak out somewhere, the pressure will drop causing the pump to come back on quickly and overcome the pressure loss. Hope this feedback is helpful! Again, please don't hesitate to reach out to our Customer Care Team if you have any other questions at 800.345.0169. Thanks for watching!
