For my application, it would have been better if there were in the strainer in addition a non-return valve would have been installed yet. I wanted to run the hose to a simple Jet garden pump, but by water from a well has to pump pumpen.Die no pressure switch. What extent also works well when the pump has managed to suck the water, but that can take about 3 minutes. The problem is, if you then switch off the pump, the suction hose is idling. That could be a non-return valve prevents. So, I have to now get such. Oh, one more thing. It was difficult at first, the plastic cable gland tightly covered to bekommen.Ich, with the O-ring of the connection to the pump is already be tight when laid in there screwed. But it was not there, the pump drew air and managed to not suck the water. Remedy managed black PVC insulation tape, which I wound 3 turns on the round thread, so it was tight. Ok that was no fault of the hose, but rather on the result, the sealing surface of the pump has not been good.
I just read in another review that as yet, a check valve should be installed. If so, then it works for me, maybe it caught
Yes, the valve has really clamped, did it consistently, now everything works fine
