Thread: Air bubbles inside liquidator

    Air bubbles inside liquidator

    I have a lot of air bubbles inside the Liquidator by the "in valve". Anyone know what could be causing that?

    Re: Air bubbles inside liquidator

    Also this may sound like a stupid question but, since my Liquidator is not running 100% now, can I just run a tube from the incoming / outgoing and remove the check valve so my filter can still run but bypass the liquidator?

    Re: Air bubbles inside liquidator

    Actually I should keep the check valve in but keep the arrow going towards the "out area" by the skimmer basket correct? If I wanted to bypass the Liquidator till I find whats wrong with the air bubbles.

    Re: Air bubbles inside liquidator

    To bypass you could:
    Keep LQ hooked up but close off the LQ with the flow regulator turn all the way off.
    bypass LQ by hooking a tube from the outflow directly into the inflow
    bypass LQ by hooking a tube from the outflow directly into the inflow with the flow regulator valve in the loop and closed off.

    As an FYI if you LQ is above water level I would try removing the check valves. They are just one more area where you can have leaking issues and you will also get a better flow without them.

    Re: Air bubbles inside liquidator

    I can just run a tube from the pipes where the little black connector is sticking out correct on both points correct?

    Re: Air bubbles inside liquidator

    Also, can I buy this tubing in say Home depot if i want a little longer tubing? If so, what kind of tubing do I need to buy?

    Re: Air bubbles inside liquidator

    Also I lost the little black ball and the cap from my flow meter so i took that out temporarily. Since taking that out, that wouldn't cause the air bubbles correct? Also, can I get a replacement flo meter for the liquidator easily? Is there a warranty on the parts?

    Re: Air bubbles inside liquidator

    In the beginning I had lots of small air bubbles in mine too, I assume from filling. After a few days these should dissipate with very few bubbles in the liquidator. If you see air bubbles in the tubing try to determine which connection is leaking. Any air leaking into your system should be on the OUT side of the liquidator because this side is under vacuum. The IN side is under pressure so any leaks there would show up as a drip. Hope this helps.

    Re: Air bubbles inside liquidator

    My air bubbles are actually inside the Liquidator unit right where the big purple plastic thing is.. On the "in side"

    Re: Air bubbles inside liquidator

    If the bubbles are tiny and attached to the side wall or fittings, they are probably due to out-gassing. As a liquid warms, it can release dissolved air back to the environment.

    If the bubbles are coming from the valve and making their way to the surface, that is a different problem and probably due to a suction side air leak.

    Re: Air bubbles inside liquidator

    Here is a video of the bubbles inside the liquidator, and it seems like there are a lot of bubbles coming out of my return jets to on top of the water, more than usual..

    Re: Air bubbles inside liquidator

    That is most certainly an air leak on the suction side of the plumbing. It is forcing air into the return side and into the liquidator as well as the returns. You can see the air pouring into the pump basket which should not contain air. It could be from the other side of the liquidator which injects into the suction side of the pump. Make sure there are no air leaks in that line.

    Re: Air bubbles inside liquidator

    so you think it could be the connections on the other side of the liquidator, where it connects by the pump basket? Should I get new tubing? Take out the check valve since I am higher than water level?

    Re: Air bubbles inside liquidator

    ok just ran a tube to bypass the liquidator, and I confirmed that the bubbles stop coming up from the return jets. so it is def a leak in the liquidator somewhere..

    Re: Air bubbles inside liquidator

    Just check all of your connections on the out side of the liquidator and make sure the tubing is seated good in each fitting. Look at your tubing too. If it is cut at an angle it may not seat good. Try to square the tubing off if you can. When you seat the tubing into the fittings push and twist the tubing back and forth until it won't go in any further.

    Re: Air bubbles inside liquidator

    Can you shoot another short video of the OUT side to wherever you connected it? You should see the bubbles entering the tubing and be able to locate which connection it is.

    Re: Air bubbles inside liquidator

    Yes will do later today. Would love to finally figure this out, for now I am bypassing the Liquidator.

    Get new tubing and remove the check valves. Put pipe dope on the barb connections before reconnecting them.

    I fixed the problem. I got new tubing and that seemed to solve the problem. Thanks everyone!
