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 :

A pump leaking water indicates that there is something wrong such as bad water seals/packings or a broken ceramic plunger, or something minor like a leak o-ring. Any of these problems can be minor at first, but prolonged neglect can lead to bigger problems.
The leak could be due to the normal operation of the thermal release valve. The thermal release valve allows hot water to exit the pressure washer if the water temperature becomes excessively high. If the pressure washer is left running while it is not spraying water, the water in the pump will begin to heat up.
Over time pressure washer hoses can start to leak, which tend to be caused from either wear and tear to the hose or damages to the seals on the connectors. The first thing to investigate is the area of the leak and if it happens to be from a connection, suspect the seals have worn out on the connector.
If you want to avoid expensive mechanic bills but don`t have the technical knowledge or experience needed to resolve a leaking water pump in any other way, K-Seal is the option for you – it can fix most leaks in the water pump casing and in the seals.

Leakin water pump
ANSWER : The water pump on a car has a bearing that blocks a hole when working. When the pump goes, it pulls the bearing from the hole and leaks. This is very common, and it was made this way for pin-pointing the issue. The water pump should be replaced.

The well pump is running, but no water is supplied to thr irrigation lines. once I put water in the pump housing by removing the pump guage the pump pumps water through the irrigation lines. when it shuts down, iloose the prime again. what should I do?
ANSWER : Sounds like you have an air leak. First check your fittings, next carefully run water over the pump seals (avoid getting water on the motor or you’ll hurt yourself and the pump if not worse) the pump will prime if the leaking seal is covered with water. Take your time and be careful and it should only be a matter of a loose fitting or simple seal swap.

I have a 1/2 horse wayne shallow well pump. At times the water in the house slows to a trickel. This will happen for about 40-120 seconds then the pump seems to kick on and the pressure is restored. I have replaced the high low switch and the problem persists. Please let me know any thoughts on the problem. Thank You
ANSWER : Check air in your water tank should be less than you’re cut in pressure..

I have a pressure booster pump installed which turns on automatically when we open the tap and turns off by itself when we close the tap, but when power goes and comes back(common in india), the pump will turn on even with no tap opened and does not turn off automatically and goes on running, some kind of airlock problem I think, when we just shut off and on water input several times, it again starts working well
ANSWER : Check to see if the output pipe has water in it when the pump swutches off the pump needs to be primed at all time what we normally find cases like this is the pump is higher than the supply or there is an air pocket on the output where the pressure sensor is

Pump comes on–the water stopped coming out—noticed the 2 wires coming from the pump hooked to points are black at end—-top of pump got warm—-have had a lot of lighting in my area—3/4 pump
ANSWER : Likely two very separate problems:

Prime failure is either mechanical wear in the pump or an air leak in the suction line. It is usually easier to look for air leaks in the suction prior to disassembling the pump to look for trouble. A clogged foot valve, a clogged impeller, clogged inlet screens, etc.

Line leads discoloring can mean many things: Line voltage may be dropping too much and/or the line leads undersized. The motor may be beginning to fail causing an increase in amp draw. The pump may be overloaded but that is unlikely.

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.

Pump making growling noise – INTEX Sand Filter Pump
ANSWER : This could be serious , ck that pump is full of fresh water , and theres no sign of sand in there , if theres sand you have a oring leaking or your aration fingers require replacment , use old nylon stocking or coffee filter on pump dish to see if any sand is getting out of filter

I am getting oil out of the pump. Can this be a leak of coolant and can it be fixed.
ANSWER : I am sorry to hear your getting oil, this is not a good thing. If you remove the pump from water and disconnect it from any power source, try removing the lower housing and take a look around the impeller if you can. If the leak is coming from around the edge of the main housing your in luck, it is probably the main seal that can be replaced without too much trouble. If the housing is cracked or leaking near the bearing I am sorry to say it would be best to start looking for a replacement pump.
