Is it true once tank has reached -30hg pump has to be shutoff and tank monitored?

I only take mine to -29 because I live in a higher elevation. And when I shut it off I do not have to monitor it holds right on.

I have, and often do leave my pump running at full vac all night completly unsupervised with this chamber.
1575662
Yes....but a second b4 you shut down the vacuum.make sure you turm the ball valve to the off position, immediately after that shut the machine....and yes monitor the gauge to make sure vacuum chamber seals properly. But remember that the higher you are ABOVE sea level you are the LESS vacuum you can achieve. ..but if you are below 1500FT no worries ....anything higher than that you will begin to lose vacuum...

I can't see any reason why the pump needs to be shut off. If there are small leaks, the pump may keep up with them. Depending on the pump design, you can get problems if you leave the pump to tank tube open, and then shut off the pump....it may draw oil out of the pump, and into your tank

I guess it would depend on what you are trying to do. If you're more specific I would love to help.

Yes after you've reached -30, you should shut off the valve and turn off the pump. If there is no leak then you should be fine and observe the silicone for bubbles to reach the top and break. You don't have to wait for all bubbles to be gone but mostly gone is fine. Once that happens, slowly release the valve and watch all remaining air bubbles shrink down to super small size. Now the silicone is ready for pouring.

I'm not an expert in this but I can tell you that the pump on my system is very quiet. There is a pressure switch that tells the pump when your tank is full. Either you haven't ran it enough to fill the tank or the pressure switch is not working (or needs adjustment). Have you tried iSpring customer service? They may be able to help

Dont think so. Water should be pumping out. Otherwise, pump motor will burn up. Make sure the water level in your tank is high enough.

Yes, it simply turns the power on and off, but not all pumps are meant to be started frequently. I have good experience with Hydor, bad experience with cheap pumps.

Ron, If it's not primed, it will burn out the pump pretty fast. You might look for a pump that does not have to be pre-primed.They cost quite a bit more, but they do make them. Instructions on this pump say, the pump gas to be level or below the hose that leads out of holding tank.

The shut off is supposed to be automatic. We see some evaporation but not a lot. I tested our water and it was 40 degrees. We also add clean water each day.

You should install a pressure switch if you want the pump to shut off automatically.

The contactor should turn off the pump once you hit ~60psi. If it keeps running the pressure sensor/switch is broke. If it keeps switching on and off the pressure builds too fast because the tank bladder is gone. If you press the valve at the top and water comes out the bladder is gone - replace tank.

It's factory set to automatically cut off when the tank pressure reaches 60 psi. It does reach that and then it cuts off.

Late response to old question, but if anyone is still interested in also monitoring water and/or gas metering, check out Brultech and in particular their GEM product.

You need to look at the various pumps offered. I guffed the first purchase and got one without a shutoff. I sold it to a friend and got another which specific addy showed a round bulb that is tethered to the pump and floats according to the water level it will turn on or off. The picture will tell all. This app read NOT to have a shutoff.

Don't think so. But there is an internal timer that's used for redundancy. It won't pump more than a certain% more than the previous times. If it is still calling for water, the safety shuts it down completely

The fitting has nothing to do with the problem. The problem is internal. I believe it is the diagram which will not let the pump shut off once it is activated. Once the water is drained and the float lowers/returns to the normal "off" position, the water never turns off.

Yes, if you have the room. The larger tank will lower the cycle rate of your pump.

Yes, Auto shut off when the water level is full. It even has a code that comes up on the display so you know it's off due to being full and not some other failure. This unit has the ability to drain through a hose so you don't have to use auto shut off if you have a drain available. Another feature is you set the humidity level you want (in % humidity) and it shuts off when you reach that level

It will probably over heat it. There is no automatic turn off. Its made for a larger tank then that

You should read the manual. It clearly states that the pump will run until reaching 150 psi and then shut off. It will kick back in once it drops to 120 psi to once again to fill the tank to 150 psi. That is its operating cycle. That is how pumps work. in order for the pump to operate at pressures up to 120 psi, the tank must maintain a pressure of 120 psi OR MORE. The pump does not maintain operating pressure, that is what the regulator is for. Adjust the regulator as necessary per application.
