Question about Rl Flowmaster Garden

1 Answer

I have an RI Proflo Model 014.3L, which like the previous one will not pick up liquid from the tank. Instead of having to push down to pressurize no force is required down but there is some resistance when the lever is pulled up and no pressure occurs in the tank/spray nozzle. I took the previous one apart and could find nothing wrong but needed something right away (kudzu was/is getting ahead of me) so I bought another one and figured on fixing the previous one later after growing season. Now I have two broken sprayers, one virtually new and one only a season or so old. Any suggestions as to how I could fix this thing? Robert Branch Walls, MS

    It is not a clogged nozzle but something in the pump. This is a back pack sprayer, nominal 2 gallons. Do you know where I can find a manual that would have trouble shooting instructions and a description/layout of the pump mechanism? That is where the problem is, perhaps a seal but, if so, how do I change it? It is not old enough for the seal to have deteriorated so it may have slipped out of place or something, hard to tell from looking at it. Nothing appears to be out of place or missing.

    Thanks, glad to know what they call these things but everything on this site appears to apply to a different model than the one I have. Mine is a 4 gallon or so backpack sprayer and the only model number on it is 014L. Looking at it again it just could not be 19 something which appears to be the model on all these sites. On the Home Depot site there is a picture of it but no model number on or near the picture. The problem is definitely in the pump, probably a seal but I do not see how to get to it for replacement. It is virtually new so doubt the seal could be deteriorated but it may have slipped out of position or something. Do you know if the FloMaster manufacturer has a web site or where I could find a manyal or instructions on how to get at and replace a seal? I have another one that possibly had the same problem. Also do you know if the "kit" has anything other than the seal in it? I looked at several of these sites, thru about page four, and none lest exactly what is in the kit and none mention an instruction sheet it the kit. Do you know if there is such a sheet in the kit? At lease you have provided some usuful information. The first "expert" was totally useless.

It's probably either a clogged nozzle or a bad gasket/o-ring. Here is a web page that talks about some things that go wrong and fixes:
Maybe it will be a simple fix, sure hope so.

Uneven burner

I apologize I've not logged in for some time and do not know what "everyone else" has had issues with.
I can tell you as a grill repair company we get 4-5 calls every week from clients complaining of poor flames, poor heat. The problem has a very simple solution and the problem is not the burners or other parts and (almost never) the regulator.
There are 3 safety features in an LP cylinder. One is a check valve that gauges pressure leaving the tank. This is a swing-arm pressed up by escaping LP. When the gas fills the manifold and gas line (because the BBQ valves all Must Be Off when the cylinder is turned on) the pressure pushes this swing-arm back into position.
The problem usually occurs with newly filled tanks because with the tank full and the OPD float displacing liquid pressure the gas "hits" the check valve swing-arm too hard so instead of registering the pressure leaving the tank the swing-arm is pressed too far and the back-pressure does not reseat it correctly.
The mechanics of the tank are designed to read higher pressure leaving and lower pressure returning as a leak and shuts-down. We still get some flow because of the OPD pushing but the tank will not allow gas flow at the necessary BTU's.
Reset: Turn off everything on the BBQ and the LP cylinder. Disconnect the cylinder and turn the BBQ valves all to "high".
Wait 5 minutes.
Turn everything off again -- and be sure every valve is completely off so no pressure is released.
Reattach the LP cylinder to the regulator and turn the tank on -- very, vert slow for the first full rotation so the gas pressure leaks through slow and cannot "hit" the check valve too hard.
Once the cylinder os all the way on light the BBQ and it will be fine.

Please let us know how it goes.
If I had one dollar for every time someone contacted us to buy burners, regulator, etc only to fix their BBQ while on the telephone with us ... I would retire!

Aqua Pro RV Water System siphon kit, #27910 - i followed the instructions and installed the kit, valve right way, arrow pointing the right way. It does not suck the antifreeze out, it blows air or liquid...

The valve should be closed while siphoning from the antifreeze. This allows the RV pump to draw it from the jug instead of the holding tank.
You can not use city water or other pressure to move it.
If all else fails and you are using RV antifreeze imply place the antifreeze in the holding tank. turn the valve open and use the faucets normally until you get liquid out of them.
Come summer you can simply add 1/4 cup of non-phosphours bleach to every 5 gallons of water to clean and purify tour lines and tank again.

1992 geo ran out of gas

Sometimes the pump will overheat when the gas tank is low, and sometimes the sock filter in the tank will pick up junk from the bottom of the tank.
Fuel pumps are designed to run in liquid gasoline to keep them cool and lubed.
You may want to replace the inline filter and check fuel pressure.

My Bissel is putting liquid into the carpet but not sucking it out

I have found a website that says

Repair a cleaner that is not picking up solution. Ensure the nozzle attaches properly. Press down firmly on the gasket to verify that it is positioned correctly. Make sure the tank lid is installed the right way. If it is not, remove it and reinstall. Verify that the hand tools are positioned properly when in use. Change the angle of the attachment and apply downward pressure. Check the water level of the tank-in-tank. Empty and replace if necessary.

The cyan isn'r printing. I cleaned and changed the cartridge. If clogged is there a way for me to unclog the nozzle?

Use a syringe filled with a liquid head cleaner. Add tip syringe with flexible hose (like the hose on the outlet head cleaning mechanic). Remove the ink tanks. Hose into the nozzle.Give the pressure slowly until the liquid head cleaner in the syringe out. Make sure no liquid is spilled in the vicinity of the nozzle. Replace the ink tanks, nozzle check and head cleaning. Is there a change from the nozzle check from the previous?

My refilled 60 # propane tank leaked and then stopped flowing.

Rick, if the tank is normally plumbed for a horizontal position, and you have it standing vertically, then you are feeding liquid propane to your pilot light, hence the frosted hose etc., and a tendency for the pilot light to go out as it has too rich of a fuel to burn. There should be no vent to allow air in as propane is pressurized, and only attains zero pressure at 40 below zero farenheit. The valve you speak of should have been the liquid vent valve which is used during filling only, and is closed during any other use. Your supply valve should be in the wide open position. The pressure relief valve is only operational when the tank has been overfilled or overheated. You should have a pressure regulator between the tank and the appliance you are trying operate. Hope this helped. Marvin

Echo model 650evl. fuel dumps through carb

Make sure the fuel tank air vent is open. If this has a Walbro brand carburetor, open the lower cover (4-screws) and check that the fulcrum lever in the body is engaged with the fuel check-valve-needle end, and also that there is a tiny spring under the fulcrum bump. Push down on the fulcrum and observe that it picks the needle up and pushes it back when pressure is released. Check the diaphragm for pliability and that it is installed next to the carburetor body with the pin side in, the thick gasket next, finally the cover. Good luck!
