We have had on 3 different time had our toilet water supply lines burst on us most on vacant apts, WHY ???? Pls help us Thanks

Are you dealing with a plumbing emergency like a leaking water heater, a sewer that's backing up, burst pipes, blocked drains, an overflowing toilet, or a washing machine that has a water supply line that's leaking? Sounds like an urgent situation. You would be best to call a plumber asap.

You should check the 1 1/2" vent pipe if there is one attached to the top of the pump casing. The vent pipe must be vented to the open air, outside of the house so the unit can breath air in and out at all times. A lack of airflow usually creates this type of problems. Leave the vent connection open to the room and flush the toilet, you will see the difference when pumping.

Your lines are located underneath house leading into the different areas of the house. It is likely that the line has burst if the temp was low enough. If it freezes again, leave a drip on your sinks to keep a flow of water going. This is crucial.

Believe it when I say the pool is not connected to the toilet.

You are not clear as to what actually happened, I presume the pool company came in and attached a hi-pressure cleaning device to your water supply. As such, they were definitely using your fresh water supply which should not have made much difference on the pressure. You say it did, ok. When the pressure went down in your water line, there is that possibility that the toilet would not fill as fast as when full pressure is available but that should only be a matter of minutes not hours, particularly if your toilet is a tank type.

You say you are in a community center, I must presume you have at least a one inch water line into your building and probably much larger, you may have a tankless toilet with a meter valve ("Sloan") on it - meaning you have enough water in your water system to support a direct flush and do not require a tank.

It could be that scale inside your pipes was disturbed by the high flow of water and the scale found its way to your "Sloan" valve, blocking the flow of water. To check this, turn off the water supply to the toilet, remove the top of the valve and clean it. Reassemble and turn the water back on.

I hope this works for you ... thanks for your quesiton @ FixYa.com

there is likely a sediment build up either in the fill valve of the toilet or possibly in the supply line. You can try shutting off the water to the toilet, disconnecting the supply line from the tank and running the water into a bucket to see if the toilet is getting a water supply. If so, then you may need to replace the fill valve. For future reference:
Any time you install a new toilet or remove and reinstall a toilet, it is a good idea to flush the water lines (as described above) before replacing the fixture. This can help to remove sediment from the water lines and the Shut off valve and prevent the sediment from building up (and eventually clogging) the fill valve.

First, see the Sears parts site for your washer:

Enter your model number (###.######) and you'll see a list of major sub-components with diagrams and parts.

New WC's are only 6 Litre capacity. But is it? check water level to make sure its high enough! you should be able to adjust the water level from the water inlet valve.

either your fill valve needs replaced or your flush valve needs replaced

Remove the tank lid and look at the fill valve. Is it a yellow valve?
This fill valve is common on the Toto Toilets and can easliy plug with debrie.

They can be disassmbled and cleaned. however, I usually just replace the valve with Fluid Master Fill valve.
You will also want to check the water coming into the toilet by turning off the water that supplies the toilet and disconnecting the water supply line. After removing the water supply line turn on the water at the valve to make sure that the water is flowing properly. Check the supply line also to make sure it is not plugged.
Be sure and place a small container to catch the water that will come from the valve. A towell will also help from making too much of a mess.
If the Supply line and the valve are clear the problem is in the fill valve.
The G-Max system denotes the Flushiing system which is a 3" flapper that allows the water from the tank to flow into the bowl quicker.
Good Toilets!

Yes, the water comes directly form the water supply line (not the tank or bowl). It is no different than the water from your faucet.
