working pressure rising really high when solenoid off
I'm setting up a new planted tank and I now have my regulator (dual stage). I connected everything for the first time and all seemed well until I turned the solenoid off.
I had everything set at a working pressure of 30 psi and bubbles were going steady at about 1 bubble per second. I then unplugged the solenoid and left everything for an hour or two. When I went back and looked at the working pressure it had gone up to 100 psi! That seems really high.
I disconnected everything in the worry that something may be wrong. I contacted the vendor, here is what I was advised:
"If that is as high as the pressure got then I wouldn't worry. All the fittings on the regulator are tested well above 100 psi.
Also the pressure rising is quite normal and sometimes the pressure will climb to 110-120 psi when the solenoid is closed, as long as the pressure returns to normal when the solenoid is open this is fine."
Now this doesn't really seem right to me, I feel like it shouldn't be rising by that much. It didn't just stop at 100psi either, it was still rising.
Would you guys be concerned? I found an old link on this form (sorry, don't have the link to it right now) where some people were having the same issue with a certain kind of regulator and the advice was to return it and get a refund.
