Hi everyone. I read several posts about doing something similar, but I'm not sure I've accomplished what I need to.
I have a large waterfall with a dedicated pump and dedicated drains. I don't need this running all night (North Texas) when it gets cold so it makes sense to winterize only that portion since it's separate from the rest of the system. I have a valve on the discharge side of the pump, but not one on the suction side. Pic attached for reference.
The waterfall outlet is several feet higher than the pump, so I used a shop vac to vacuum the water out of that line from where the pump basket goes. That seemed simple.
I then reversed the vac and blew air into the suction side until the returns for the waterfall bubbled. There is no valve to isolate and air lock the drain so once I'm done I can hear water filling back into the suction lines from the drain.
How do I keep these lines full of air without adding another valve?
I thought maybe to seal up the pump and attach a compressor to the drain plug on the suction side and put air in that way so the system says sealed. Is that what I need to do or am I overthinking this?
Thanks in advance!
