Re: Seeking false water flow alarm suggestions

Does anyone have a spare 1" male threaded part for the Potter VSR-ST union? I have access to the rest of the switch, but the part needed to screw into my pipe is missing. I'm sure someone has run across a non-operational Potter VSR-ST and is willing to sell me the union piece I am missing,

As long as I'm paying for monitoring, I might as well have the switch. I guess I'll just get the delay switch. On 10/12/2016 10:57 AM, rongreenman . wrote: You'd need a hydro pump to overpressure your system but although your switch is doing what it should as mentioned, that switch does not

Re: Seeking false water flow alarm suggestions

You'd need a hydro pump to overpressure your system but although your switch is doing what it should as mentioned, that switch does not have a built in time delay according to earlier reply. Changing it to one with a time delay would solve the problem. But why not just disconnect it. The is no

I assume attaching a water hose to my test valve wouldn't help, as the pressure from inside and outside would be the same. How do you suggest I add pressure to my system? On 10/12/2016 9:52 AM, Steele, Andrew wrote: I've heard of contractors pumping up sprinkler systems a few lbs over

RE: Seeking false water flow alarm suggestions

I've heard of contractors pumping up sprinkler systems a few lbs over domestic supply, rather than leaving the sprinkler at supply pressure, so there is no subsequent flow alarm after running an Inspectors test. For example, our City water pressure trends up in the very late hours, then down

Re: Seeking false water flow alarm suggestions

My guess is the flow switch is doing exactly what it is supposed to do. Replacing it would give the same result as the working flow switch already there. The check valve would, if working, allow water at a higher pressure into the sprinkler system leg only once and then it would check shut.

Re: Seeking false water flow alarm suggestions

Mike is right. However the problem relates to the draining and refill, so something has changed. It may be as simple as a check valve that was holding previously, but is not now. A possible solution would be to put a time delay relay between the VS-SP and the bell. Just a few seconds delay

Re: Seeking false water flow alarm suggestions

I'm not on municipal water. I'm on a well, but when my 2HP pressure pump kicks in, it does build pressure rapidly. I had to replace all the sprinklers early on, due to a recall, so that probably eliminated any air pockets... until this latest total drain. I'm beginning to believe the only

RE: Seeking false water flow alarm suggestions

Barry, The unwanted waterflow alarms are caused by the fact that the VS-SP does not have a retard and you are getting water surges because you are connected to a municipal water supply and have some air pockets in the sprinkler system. They are called unwanted alarms, not false alarms. The

Re: Seeking false water flow alarm suggestions

The check valve prevents water from coming back down and entering the home system, not the other way around, but I'm open to exploring any options. Any suggestions on how to check and repair this? I'm not sure if the picture was attached, as I can't see it here, so I'll give a link to
