Hi all. I just installed a new jandy blower. I turned it on and it's nice and high powered. My question is when I turn it off, it still blowing bubbles. Is that normal? Its definitely not running. Does it hold air and pressure somewhere? Thanks.
I assume you are still running the pump but the blower is off? If so, air is brought into the stream of water into the spa without the blower, That is normal. Our spa does not have a blower and has plenty of air entrained in the water flow when the pump is run at high enough of a rpm.
Yes sir, the pump is running into the spa. I am heating it up as we speak. Will the bubbles eventually stop, is this just air trapped in the system or new air now coming in. I never had bubbles before, but my old blower was trashed. Thanks
One more thing, there is a on off valve right after the blower. If I close that ball valve the bubbles will stop. So I guess now it's just sucking in new air from the blower pipe. When I change the returns to the main pool, do I want the air bubbles there, or should I close the ball valve.
The jets usually have "Venturi" fittings that pull in air due to low pressure generated by water moving past a restriction. Once the air is started, the air can continue as long as there is water moving through the venturi fitting.
Hi. No I just have an old pump... makes sense about the air keeps pulling in. I plugged the hole at the bottom of the spa wall, so you it does spillover. I usually have it set like that all the time so it skims the spa water too. Figured that was good, only started doing that this year.
When you say a valve, you mean so water cannot flow back up into the blower? These handy blowers have it built in at the neck of the unit. That is why I selected that model to replace whatever I had. Thanks
