Pool pump leaks


This will be a ceramic seal that seals between the impeller (motor side) and the pump housing. The seal is hard to change if you don't have a shop. If by chance you do get it apart be sure not to contaminate the new ceramic seal surfaces. You should have new bearings installed in the motor while it is down and apart.

the absence of the copper cone will not cause a leak, however, there is a different shaft seal that needs to be used in lieu not having the copper cone installed.

If the impeller is damaged or cracked, that can cause a leak at the shaft seal. If you replace the impeller, the shaft seal will most likely need to be replaced as well.

I have a Yamaha yz 125 2003 and there is water leaking out the bottom through a small whole and was wondering why it is doing that as it has just started doing it recently


This is telling you your oil and water seal need replacing ASAP do not ride until fixed as you will seize bottom end guaranteed !
there is small seal each side of your water pump impeller when you take the impeller out replace both even if only one needs doing as you will be going back to replace the one left soon after as they always go together..
Most people would not do this repair without replacing the impeller as well - usually the impeller starts to wear groves where it spins inside the seals then damages the seals So you get the theory behind replacing the whole lot as old impeller can damage your new seals
The seep hole is designed to give you warning of burst seal before its way to late as without the seep hole leak you would have no idea you are leaking coolant into the motor
You can do your self its a bit of work but not complicated - if you do your self don't forget to change your engine oil couple of times after first few rides reduce any risk of having coolant inside it where it should not be
good luck regards Jamie

My pump is leaking .What causes that and how do I fix it


Thank youfor posting your question here on Fixya.com. The leak is likely caused by a defective pump seal. If you look at the parts breakdown at http://www.star-pool.com/assets/Hayward-Pool/Hayward-Manuals/Hayward-SP2610X15-Super-Pump-Parts-Diagram.pdf you can see the seal and the other parts that must be separated in order to replace the seal.

THE HARD WAY! Once you are sure the seal is defective you need to buy a new one along with a diffuser gasket, a pump housing gasket and some pump gasket grease.

The 4 housing cap screws and the impeller must be removed in order to remove the 4 motor cap screws. The hardest part of this process is removing the impeller. The cover on the other end of the motor should be removed and the motor shaft held with a wrench. The impeller must then be removed by turning it with a large pump pliers or by inserting a screw driver into one of the holes on the outer edge of the impeller in order to turn it counterclockwise with the shaft held with the wrench. If this damages the impeller it should be replaced.

Now remove the 4 motor cap screws and everything is apart except the seal. Half of the seal can be removed from the motor shaft and the other half from the seal plate. Placing a socket on the back side of the seal that is on the seal plate allows the seal to be removed by tapping it with a heavier tool (hammer or pump pliers). Clean this area, apply a little silicon adhesive to the area and insert the new seal half into the seal plate using the instructions that are included with the seal.

Use pump gasket grease on the pump impeller gasket and reassemble the completely reassemble the pump.
THE EASY WAY!
Remove the piping from the motor and the electrical conduit and wires from the end of the motor. Bring the pump to Leslies pool supplies (I don't work there or own any of their stock) . If they are not very busy then they will do the above and only charge you for the parts while you wait.

I have replaced so many seals I almost always do it myself at the pool site but it is not easy for the first timer.

Thank you for posting your question here on Fixya.com.


Your pump seal is the most likely culprit. As the water leaks around the motor shaft it will trickle down to the bottom and drip off. Double check your drain plugs first to be sure it isn't one of them dripping. Assuming they are not, it is the seal.


Waterway pumps use a press-fit 1000 seal. It is not an 'easy' seal change compared to most. You may want to take it to a pump repair shop for the seal change and the shop warranty that should come with it in case it is not done perfectly. If you do it yourself, get a piece of 1" rigid PVC about 8" long with clean-cut squared off ends to use as a driver.


Remove the front pump cover exposing the impeller. Remove the cover plate off the back off the motor to expose the end of the shaft opposite the impeller. Depending on the motor, lock the shaft with a wrench, screwdriver or allen key then spin the impeller off counter-clockwise to expose both halves of the seal.


Remove the old pieces completely and replace them. Put a SMALL bead of silicone caulk along the beveled edge in the seal plate, line up the metal cup making sure you NEVER touch either seal face in the process, and then punch it down with a mallet and the PVC pipe. The ceramic piece can get a small amount of a synthetic lube or just use a little soapy water to ease pressing it into the impeller recess again making sure not to touch the polished seal face. Use clean rags or pieces of paper to cover the seal as you work with it.

After doing a load of laundry, the machine won't drain


If your Whirlpool FRONT LOADER is leaking, the following link can give you guidance on how to inspect the washer to determine where the source of the leak may be coming from:

http://www.fixya.com/support/r3576656-washer_leak__front_loader


Most commonly, the source of the leak comes from the door bellow (gray rubber seal). They do wear out with age and can develop small rips and tears. A routine inspection of the perimeter of the door seal can determine if you have any holes. If the seal is damaged, it must be replaced. The following link explains how:


http://www.fixya.com/support/r3574186-installing_a_door_bellow_on_a_front_load


The manufacturer recommends that you leave the washer door open between washes to prevent the seal from becoming permanently stretched. Once the seal stays compressed constantly it can stretch and not seal properly. In addition, leaving the door open helpd let the wash tub air out and prevent mold, mildew and musty odors.

If you suspect you have an obstruction somewhere in the drainage system, the drain pump reservoir needs to be cleaned out. The following link explains how:

http://www.fixya.com/support/r3574284-checking_the_drain_pump_on_a_front_loade

If you check the drain pump reservoir and the problem still persists, you may have a pump with a damaged motor/impeller, or something lodged in one of the drain lines. In particular, the drain line that runs from the bottom of the wash tub to the inlet side of the pump.

I recommend you remove the inlet hose, as well, and inspect for clogs. In is common for small garments to become lodged in this area and restrict water flow to the drain pump. Check the output drain line for obstructions as well.

It does not take much to damage these small drain pumps. The error code is generated if the drain cycle exceeds 8 minutes. So...if the impeller or motor become damaged, and the pump does not pull water at the correct volume, you may still experience the drain error. In this case, you will have to replace the pump in order to get the error to clear. The following link explains how:

http://www.fixya.com/support/r3574350-replacing_the_drain_pump_in_a_front_load

Replacement parts (if required) can be purchased at any of the following web sites:

searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
repairclinic.com

Prices vary between sites, so shop and compare. The first three sites listed also have helpful exploded view parts illustrations to assist you with locating and properly identifying the parts you may need.

Leaking #1 pump on Arctic Spas Cub hot tub.


I found out that the pump impeller can be unscrewed from the motor shaft by turning the impeller while keeping the shaft from rotating. There is a brass shaft coupling embedded in the back side of the impeller. This allowed me to remove the leaking seal assembly inside the pump by tapping it out gently. However, instead of just replacing the seal, I decided to replace the entire pump with a newer version. Cost was only about $25 more than replacing the seal and gaskets. The pump-motor assembly has been reinstalled in the spa and there are no more leaks.

Water pump doesn't work but there is no water leak it can be just a sensor problem?


No, but it could be the impeller inside the water pump, has come loose from the impeller shaft.

A leaking seal indicates that the bearing, or bearings, for the impeller shaft are bad.

I have replaced water pumps, (With a brand new one), and have had to remove it, and reinstall with another one.
Why?
Impeller is spinning around on the impeller shaft. The machining done was a bad job, and the impeller wasn't staked to the impeller shaft.

Water leaking during drain and spin


Hi!

You Need to check the following--

The fill hoses : These are located behind the washer and are connected to the water mixing valve and faucets. Pin holes and cracks on the hoses may cause them to leak.



The water valve: The water mixing valve is located behind the washer. The fill hoses connect to the water mixing valve. Inside of the valve is that the water gets directed to the filling spout. Water leaks happens when the valve develop pin holes or cracks. Bad fill hoses or water valve could be the reason why the washer is leaking water.


The Filling spout: Is just a directing part, this part directs the water from the water valve to the tank. Pin holes and cracks is what make this part to leak.


The tank : The major cause for the tank to leak is through holes or cracks that the tank develops because of vibration or metal items hitting the tank during the spin cycle.


The tub seal : The tub seal is made of rubber, it is connected between the transmission post and the center of the tank. Leaks developed when the seal gets worn out and it looses the ability to make a good seal between the transmission and the tank. A crack tank or worn out tub seal could be the reason why the washer is leaking water.


The overflow tube : This tube is use to direct the water away from any electrical parts like the motor in case of an overflow cause by a bad water mixing valve or bad water level switch.


The pump : The pump job is to remove the water from the tank to the drain pipe. This pump has an electric motor and an impeller. When the pump motor is turning, any water that falls in to the impeller, is push out to the drain pipe.

Most leaks are cause by a worn out seal between the front pump housing and the rear one.


The drain hose : The drain hose is made of hard plastic and some times it develops pin holes and cracks leaks. Bad pump or drain hose could be the reason why the washer is leaking water.

Thanks for using FixYa and do rate the solution as Fixya if found helpful.
