Please check ''TANK FILL'' hose quick connector & ''LIQUID'' hose on ISV Tank & make sure both valves is opening properly.it sound like(one of those) close! If valves is Ok then check tank fill solenoid, it may need to rebuild or replace. If those are OK, replace ''TANK FILL'' Hose.
I hope this will help you to solve the problem, if so please vote for it. Gool luck!

Won't refill from source tank. Trys to, solenoid buzzes, then quits trying.


If it is a 34700-2k or 34700z it could be the check valve that is between the solenoid and the block if it is a 34788 the check valve is brass cap on the side closest to the solenoid. you should be able to blow through the check valves one way they only take 3 psi to open if it will not open it will need replaced

I replaced the black ink with a refill cartridge and its saying black ink volume unknown. went back and got a new refill cartridge says same thing...please help?


All cartridges are "tracked", which basically just means that when you run the cartridge down on one printer, if you put it in another it will still appear to be empty. With refilled cartridges, your printer may see it as empty because it has been empty once before. If your printer accepts it and still prints, your best option is just to let it go. Print with it and just ignore the message. You'll know when you need a new one because your printouts will start to fade or streak.

If your printer won't accept it or print at all, you can try performing a hard reset to try and trick the printer into thinking it has a new cartridge.

1. Open the cover and take out the cartridges.
2. With the cover open, unplug the power source from the printer.
3. Wait 20 - 30 seconds for the printer to reset.
4. Install the cartridges and close the cover.
5. Plug in the power source.
6. Turn the printer on and let it go through its regular startup process.

The hard reset option is not a guaranteed fix, but it is a good idea to try; it works on many models and brands very well but there are some that fail to recognize the refilled/remanufactured cartridges after a reset.

I have a ge reverse osmosis filtration system and recently lost pressure and tank capacity. I have only had the system about a month and my water has been tested fine. I did leave town for 10 days, could...


Make sure that all valves are in the open position.
Try to recharge the water storage tank. Here are the steps to follow.
* In General: When any type shut-off valve handle is positioned so that it is parallel or in line with the tubing that enters the valve, valve is OPEN. When handle is turned perpendicular to tubing that enters valve, valve is CLOSED.

Necessary Supplies:
1) Tire Gauge marked in 5psi increments (ie 5, 10, 15, 20psi, etc.)
2) Bicycle tire pump for standard type bike tire valve
To recharge RO system tank:

1) Close cold water feed valve (valve located at some point along the cold water line from street plumbing).*
2) Leaving RO tank valve on, turn tank on side & locate valve stem on bottom side.
3) Remove stem cap.
4) Drain all water out of tank through open RO faucet into sink. (Continue to leave RO faucet open throughout procedure)
5) If current tank pressure is insufficient to empty tank, apply tire pump to valve stem and pump 10 – 15 times. Exit flow will increase and then gradually decrease as pressure equalizes. Do not overcharge internal bladder of tank during this
procedure.
6) Repeat step #4 until tank is completely empty. (Tank is empty when additional pumping produces no more water)
7) At this point, adjust EMPTY tank to exactly 7psi. (Gauge reading midway between 5 & 10psi is sufficient)
8) Turn off RO faucet.
9) Replace cap on valve stem and reposition tank in upright position.
10) Open cold water feed valve.*
11) System water is useable immediately, however, tank will take 3-4 hrs to completely refill.

How do i refill the coolant in the car after replacing upper hose


hello, your car has a reservoir tank were you put the coolant in at all you have to do is start your car and it'll draw coolant from there after your car runs a few minutes check your coolant reservoir tank it;ll probably be close to empty also since you took your hose off you'll have air in your system that you'll need to bleed out of the system otherwise your car will over heat and you wont get proper coolant flow the bleeder valve is a small brass bolt that you can use a wrench to open and close it with, with your car running just open the valve until you see coolant flow out then close it do this till you get a solid stream of coolant flow and check your reservoir often while doing this keep it full.

Culligan RO sstem has recently stopped producing more that 6 oz


This might be a possible tank pressure issue. This could also be a clogged filter. I would first check the tank pressure by using the following steps

Necessary Supplies:
1) Tire Gauge marked in 5psi increments (ie 5, 10, 15, 20psi, etc.)
2) Bicycle tire pump for standard type bike tire valve

To recharge RO System Tank:

1) Close cold water feed valve (valve located at some point along the cold water line from street plumbing).*
2) Leaving RO tank valve on, turn tank on side & locate valve stem on bottom side.
3) Remove stem cap.

8) Turn off RO faucet.
9) Replace cap on valve stem and reposition tank in upright position.
10) Open cold water feed valve.*
11) System water is useable immediately, however, tank will take 3-4 hrs to completely refill.
