My GE Filtration system tank does not fill up with water .. The connections look fine

Make sure any water valves (Cold or Hot) for water heater are not leaking first. Gate valves may leak at the packing nut over time and drip on top of tank. If water is leaking from the top of the water heater itself the tank is corroded and water heater will need to be replaced.

The eductor assembly is plugged. This is where the brine is drawn in to regenerate the system. It is the space capsule looking thing on the left side of valve. The owners manual has directions to repair this. You may find your manual here.

There are two water lines connected to water heater.
One is marked Hot and the other Cold.
The shut off valve is on the Cold line.

To eliminate sand and dirt from entering your water heater, the 'sediment' filter should be installed on Cold line.
Sand and dirt are sometimes called sediment, but this type of sediment is not the same as calcium carbonate sediment that accumulates inside a tank that receives hard water.

When you have hard water, then water heater makes calcium carbonate 'sediment' deposits that accumulate in bottom of tank. A 'sediment' filter will not prevent this problem.

If you have hard water, to prevent calcium carbonate from forming inside tank, you need a water softener.
Water softener will prevent calcium carbonate sediment forming inside tank.
However water softener will shorten life of water heater anode rod.

A 10 year old water heater is at the end of its life expectancy. No sense replacing a gas valve to have the tank rust out next month. I'ld replace the whole unit. Also, install a drip pan, under it and a WAGS safety device. Any water in the pan and the WAGS will shut off he Water and Gas. If your water heater has an expansion tank near by, replace that too.

Water on floor usually indicates that the tank is leaking and time to replace the whole unit

It sounds like there is quite a bit of sediment in the water. The filter you are using may be a very fine micron 5-10. Try using a 30-50 micron filter.

The mouse must have been in one of your product bags...depending on the deterioration of the carcus; you may have already injested some of the decomposing material.
1. Turn off the water supply and remove the top cover
2. Make sure you have rubber glvoes. Drain the holding tank and remove and dispose of the remaining salt tablets/product left in the tank.
3. Yes, clean the tank with a disinfectant (bleach) and rinse thoughly. Be sure to rinse the tank...you don't want high levels of bleach in your supply lines.
4. Fill with new/clean softner tablets and return unit to service.

I had same system under my sink for same amount of time and have since then removed entirely for health reasons related to Ro Systems. Mainly the tanks becomes contaminated [alge build up]and my faimly had constant nagging stomach aches which took a long time to resolve untill we decided to disconnected and throw out our "beloved healthy RO System" and decided to install a bi annual disposable type filter system. If you are expereanceing this I would advise the same as for the leak ,There are so many connections under there and it is usually not the tank but the fittings in lines some where and the reason it looks like the tank is because that is the lowest point the leak has traveled. So check all your fittings and if you decide on simple water filter I will advise you.

Please rate. Thanks jj505

The tank was full of water . The blatter in the tank was empty so I pumped six pounds of air into it and it works great.
