How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

One of the most obvious signs that your carburetor needs cleaning is the development of popping and “sneezing” sounds when the pressure washer is running. These sounds are often an indication that there is some sort of imbalance occurring in the air and fuel mixture.

Surging Pressure Washer Troubleshooting Tips

This can be confirmed when the trigger is released and the pressure builds back up to a normal level. It is telling the operator that the water supply does not meet the pump`s recommended flow rate. Check that the water supply and inlet screen are unrestricted.

Check for leaks

There could be small leaks, holes, or tears in your garden hose or high-pressure hose that are causing your pressure washer to lose pressure when you pull the trigger. If you find leaks, plug the holes or replace the hose, which should solve your pressure issues.

The reason for this is because a build up of water pressure. On the water inlet or coupling the water can cause a pressure build up, popping the garden hose off. The aqua stop is a valve in the end of the garden hose connection that restricts water flow.

If the washer is noisy during the spin cycle or is leaking from the bottom of the tub near the transmission, the tub seal and bearing are likely defective. Replacing the tub bearing is a very involved repair and will require disassembling most of the washer.

If the pressure washer trips the fuse board or blows the electrics in your home, make sure there`s no water in the switch or the other electrical items – and again examine the capacitor if your model carries one.

A dirty inlet or discharge valve is the most common cause of a pulsating pressure washer. Dirt or hard water can get caught up in these little divots. It is important that you clean out these pieces every so often to prevent these kinds of problems.

How Do I Tell If My Unloader Valve is Bad? In most occurrences, the first symptom of an unloader valve going bad is no pressure from the wand when the trigger is pressed. This happens when the unloader valve gets stuck open and does not allow water to enter the hose and trigger.

If your hose is 100 feet or less, no, your hose will not likely have issues. However, if you want to use a hose that is a few hundred feet long, you will lose a noticeable amount of water pressure. Most pressure washers are not sold with long hoses because the best pressure is achieved from a shorter hose.

If the machine is pulsing whilst in use, it may be that the accessory you are using has a blockage. Clear by soaking the accessory in warm soapy water and then rinsing out under the tap.

Turn Off the Machine

Turn off the water source. Don`t immediately detach the hose from the machine if the main water source is still on. Pressure has built up in the hose and could cause injury. Now, turn off the safety lock on the pressure washer and pull the trigger to remove any excess water and pressure.

The most common reason your washer makes banging sounds during the spin cycle is that an unbalanced load has thrown it out of whack. When you put your dirty clothes in your machine, make sure to distribute them evenly in the drum. Heavy items mixed with lighter ones can cause it to spin unevenly.

It can be caused by various factors, fuel injection problems, bad spark plugs, a malfunctioning air sensor, might be a dirty air filter, and troubles with the engine control. Other issues of the fuel ignition system can also trigger surging when stopped.

Honda pressure washer units are the most popular gasoline powered washer in our selection. Its HONDA engine is capable of producing 2,000-3,000 PSI and 2.3-3.0 GPM (depending on the model).

Running a pressure washer without water can cause irreparable damage, sometimes instantly, sometimes gradually over time. Either way, you are better off not risking rendering your machine unusable.

Why Does My Appliance Keep Tripping the Breaker? An appliance that consistently trips your circuit breaker is not only annoying, it could be the sign of a bigger problem. The most likely reasons for this problem are an overloaded circuit, overheated appliance, electrical short, or ground fault issue.

Pulsation generally occurs when a liquid`s motive force is generated by reciprocating or peristaltic positive displacement pumps. It is most commonly caused by the acceleration and deceleration of the pumped fluid. This uncontrolled energy appears as pressure spikes.

And when a PRV fails, it can lead to an explosion. Damaged equipment, disrupted work flow, and even injury may result. Why take that risk when you can easily tell whether or not your pressure relief valve needs replacing or repair.

The difference between regulator and unloader occurs when flow downstream is stopped. A regulator redirects flow through the bypass port, maintaining full system pressure. An unloader valve closes the fluid passageway and traps pressure in the discharge line.

A trapped pressure unloader valve opens when there is an increase in pressure, so when the trigger on the gun is released (open) the pressure increases and opens the unloader valve sending the water back to a holding tank or back to the inlet side of the pump.

Is your Karcher Pressure Washer making a humming or buzzing noise when you try to use it? Don`t worry, we`ve got you covered! Chances are, the capacitor has failed and needs to be replaced. But don`t panic, replacing the capacitor is an easy and inexpensive way to extend the life of your pricey power washer.

If your washing machine won`t start and just clicks, there may be debris in the washer drain. Check the drain to see if there`s any debris (particularly large items, like coins) that may be stuck inside.

Started washer, heard ‘pop’, water started coming out of bottom

ANSWER : Thats not good. Sounds like the seal blew out. Inside the unit there are seals that seal up the parts where they are bolted together. Also there is the pressure connection that could have blown out as well. To determine which is the problem you will need to dissassemble it.

Couple of guys tried to help me on this, perhaps you guys could come back. I forgot to mention there is a pressure tank bladder type on the discharge side. Could the air in this tank be messing with the prime. I checked the intake. It has water in it after bleeding air from the discharge system where before it was dry before purging air. I think there is air in the system and wonder if it is coming from the pressure tank?. i open up one of the discharge valves and a lot of air comes out. Should I put a valve on the pressure tank to take it off line until I get water from the well?

Mar 12, 2010 – Could it be the check valve? I took it off and the flap appears to be working correctly. This well has been here a long time. Never given me any problems. I do have galvenized couplers on the discharge and intake sides. Old. Could these be leaking even though they show no sign of water? The discharge is able to hold 30 pounds easily overnight. I do not hear any vacuum in the intake when I take it off. Could the pipe to the well have a leak? I know I would have to insert a sleeve but I do not want to go through the hassle if I do not have to. I had put on a brand new pump from the hardware store that did the same thing so I think that would elliminate the pump as being the problem.
I disconnected it for the winter and rehooked it up. The galvanized couplers on the discharge and pump side are old but do not appear to be leakeing as I taped them well. The check valve seems to be functioning well as I took it off and the flap works correctly. The well is not pulling water. there does not appear to be a vacuum on the check vale when I losen it. could the check valve be bad? I am aware I might have to resleeve the well, but do not want to hassle with this if I do not have to. I want to eliminate everything else first. i put another brand new pump on it to see if it was that. That partiuclar pump which was the same thng did not work either.
I took the pump nose off and looked at it. The one way valve appears to be working fine. The impeller is working fine also evidenced by when I turn it on witht the discharge cap off, water shoots out. When I open one of the discharge valves and turn it on, the pressure drops to 10lbs. At this point the prime water has moved through the pipe and and the pump does not soound like it has any water in it. I pull the cap off and have to “reprime it again.” It again goes back to the pressure gauage rapidly fluctuating while pump on. I disconnect pump on intake side I hear no vacuum. The guage is on the discharge side. The seals on the pump nose do not look frayed or damaged. The pump is not leaking water in any of the joints. The pipes on discharge and well side do not appear to be leaking.

ANSWER : My friend, please boil your question down. Your title has to do with riding mowers but the leaking, bladder, impeller, air bubbles, pressure tank, check valve comments seem to be migrating toward a pump of some kind – well? spa? pool? irrigation?

Briefly, any system that involves a water source, a water moving device, water storage device and ultimate useage is subject to leaks … into the system and out of the system. If this is a well and you have air in your system, your pump may be sucking air at the well or any loose connection between the tip of the pipe and the inlet to the pump. Your bladder could have failed but from what I can get from your comments, this is not the case. On the pressure side, neither air nor water will leak in … only out.

Please recheck all connections. Make sure your check valve is installed correctly and not leaking. The check valve assists the foot valve, which may have failed.

I am more inclined to think your well may be at the end of its useful life. To prove or disprove, you could have a plumber put a vacuum gage on your pump. He or she can answer this question is about 90 seconds based on this test. Expect to pay for one hour of time, which will be less than the time you have already invested in your project.

I have used the McCulloch (FH180A) three times over the course of two years. On my fourth use the pressure washer just surged on and off and I would get a tiny spray from the gun each time it surged. In other words it would do nothing. Please help… very frustrated. Thanks

ANSWER : Sounds like the problem could be low input water flow or pressure. There could be crud on the intake where you hook up the garden hose, there could be some other sort of blockage. Try hooking it up to the hose and pull the trigger (with the power switched off) and wait to see if water comes out the tip. Also look at the tip(s) themselves. sometimes a piece of crud gets into the hose and then clogs the tip.

I bought a honda pressure washer power boss 3000. I load the gasoline, start the machine, but pressure water is not coming out
from the trigger. i tried so many things , but can t get started.

ANSWER : If you are using a water tank for water supply, remove the water supply line from the pressure washer and connect a water hose from a faucet. Turn the water on, then crank the engine. Pull the trigger of the spray gun until water comes out. When then water starts to spray properly the release the trigger, shut engine down with pressure on the line then reconnect the water supply from the tank to the pressure washer. If this fixes the problem then the problem was “air-locked”! Happens alot with new pressure washers that have never been run. If you need any other help, please email me @ [email protected]
