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 :

Water leaking from a loose connection can cause the unit to cycle on and off. Verify if the pressure hose has an O-ring at the connection. If missing, this will also cause the unit to cycle on and off. While the unit is running look for any water leaks that may cause the unit to turn back on.
Trigger handle / hose O-ring – If water is leaking near the pressure washer trigger handle or high-pressure hose, you may need to replace the O-ring that sits between the spray wand and trigger handle, or the ones on either end of the hose.
Surging occurs when the pressure is fine and then weakens. It is caused when the flow rate for the pump cannot be supported by the water supply. Problems can mount from there so it is important that it is dealt with as soon as possible.
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.

Replace leaking, punctured or rusted hoses. Clean your drain pump every three months to avoid clogging. You might be using more detergent than necessary. In this case, your washing machine will stop and try to absorb the excess foam in its drum.
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.
Any leaking may be fixed by tightening the connectors while the water and pressure washer are turned off and the pressure has been bled by pulling the trigger. Also check the o-rings; grease or replace if damaged.
The engine of your pressure washer may rev sporadically because it is experiencing an intermittent blockage of the air that it needs to function properly. The first thing that you should do is to check the air filter for clogs caused by debris or dirt. Clean out any clogs that you find and the erratic revving may stop.
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 the machine is pulsing when on standby, is the garden hose supplying the pressure washer fully uncoiled? 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.
DON`T Let the Machine Run Too Long Without Pulling the Trigger. Pressure washers operate under pressure, and that pressure needs to be released by pulling the trigger. If you let the machine run for two minutes or longer without spraying water, then you could damage the pump.
Problem: The pressure washer cuts out.

If your machine cuts out occasionally, it could be because you are using an electric extension cable. Extension cables must always be 13 amp constant rating and no longer than 10 metres. Please check your operating instructions for correct specifications.

Each time the power cord is plugged in to an outlet, the Reset button on the GFCI module must be pressed down to connect to electricity. Check to see if the Reset button has been pressed. Next, confirm the small plastic window below the Reset button shows RED in the window.

It depends on the pressure washing equipment you purchase. New pressure washers will be rated with a number of hours they should last. For example, if it is rated 500 hours and you use it fewer than 50 hours throughout the year then it will last you more than ten years as long as you keep it well maintained.

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.

Hunts on and off when trigger is not depressed, checked for leaks and screen, also discharge, still does it.
ANSWER : There could be a small bit of grit stopping the non return valve in the inlet pipe from sealing fully which would allow a pressure drop causing it to hunt. The valve may also be just plain faulty.and require replacement.

My chainsaw leaks oil out of a small hole or drain just below the base of the bar. is there anyway to way to stop this
ANSWER : Are you sure you aren’t talking about the chain oiler system? There is to be a small amount of oil to lubricate the bar and chain.

All bar oil leaks from the bottom in a stream while engine is running
ANSWER : Take bar and chain off and clean oiler its not ably to close so to speak

2 cycle mantis tiller leaks gas thru the carb. – will not start?
ANSWER : If it leaks gas,it can **** air.you have to find out whats leaking and stop it.

Poulan 14″ gas leaks bar oil all over, plenty on bar/chain, using thin synthetic oil.
ANSWER : Use actual bar oil sold for that purpose. It’s thicker and won’t run out like water. Synthetic oil is very thin does not have the proper density.

Turn water on then actuate wand trigger. Pressure washer leaks when wand trigger is actuated and has very low pressure/flow output. After releasing trigger the pressure cycles on – off at approx 1 second interval. I suspect that the plasstic oulet tube is leaking causing low pressure leak out of bottom when trigger is actuated and causes pressure switch to cycle when the trigger is released. Any Help? This pressure washer is approx 18 months old!
ANSWER : You gave a very close solution yourself for the problem. But other leakages can cause such symtoms.Forexample a leaking head or a leaking chemical inlet. These can be caused because the spill valve (pressure control valve) is stuck. When this valve stucks it will leave a micro switch ON. So the machine keeps working with the gun closed. This will in turn creat internal pressure and damages the head, valves and chemical non-return and even damage outlet hose. So besides fixing the leakages you must check and service the spill valve. I often replace the spill valve. One must also checks if the micro switch is faulty. Now very important that what you mentioned that the machine cycles at one minute intervals, with trigger closed…this is most probably always the spill valve fault. If you open machine you see a place where there is a wire..this belongs to the micro switch…under you find the spill valve. Intake and suction valves may now also have a fault. Also there are systems with non-return valves at the machine outlet. You have to tackle by elimination. Fix the leakage..then tackle spill valve and micro switch.

My petrol lwan mower won’t start! I have checked the spark plug and cleaned it, checked the air filter and have also cleaned it they are fine. I have also taken the carburettor to bits and have cleaned it and still no joy. It has a full tank of petrol and the oil is fresh also. I checked the air line and the petrol pipe and these are all ok. When i sprayed quick start into the air filter my lawn mower started up straight away. Then cut out once it had used it up. my throttle plate had also snapped which i fixed and my clutch cable had also come loose which i have tightened and is now fine. The lawn mower is only 3 years old and has not been used for 2 years as my neighbour just went out and brought a new one. so i am trying to get this one started as my electric one has just died on me. I have also been having a go at setting the carb today buy adjusting the air pin but still no joy. It is firing though but just wont start!!! can anyone else suggest anything that might be wrong. Also do these have chokes as i can not find one for it. MY LAWN MOWER IS A POWER DEVIL 3.5HP
ANSWER : When you sprayed the quick start into the thing and it started and ran out, I think the answer sits here you also said you pulled the carb apart to bits it is apparent to me you did not do a thorough job!! Just the fact that you stated that it has not been started for two years tells me that you are having petrol movement problems. For one thing to get started check all the little orifices associated with petrol movement this is surely where you will find your answer to get the machine running, I know this for a fact. You will receive joy just as soon as all your do diligence is finished. If you cannot find the choke on your machine you surely cannot buy one for it. Maybe this repair stuff is just not your thing, maybe as your neighbor before you, you should maybe go shopping and then you will achieve the full amount of joy you are in such desperate need for. Going from electric power to petrol power is a total different world. I think that now my answer to your question is almost as long as your question, so I will be stopping because my fingers are tired of all this typing, GO BLACK HAWKS! Good luck PAL
