Circupool RJ 45+ Installation

[Rancho Cost-a-Lotta]

Here's an option if you plan to move the SWG...

Cut the cell out of the vertical line. Be careful to allow at least 1.5" (cut in the middle of the 90s and unions) on each side of the unions for couplers.

Cut the long horizontal a few feet back behind the flow switch. Replace the cell with a PVC coupler. That will raise the long horizontal line so you can mount the cell off the ground behind the post. Reconnect the line downward with a couple of 90s.

Another bad sketch, but you'll get the idea.

Go check the first pic again. LOVE the idea, don't think he has the room as the down pipe was used there to pivot with the side of the (dodecahedron ?) pool.

Hard to tell from the pics if it would work.

The 90s (in yellow) would maintain the pivot angle. After removing the cell, the lower 90 would just come up to reconnect on the downpipe.

What you're suggesting was option one in Post 6 of this thread. My concern with it now is that if the bubbles don't like to go down, this still has a down segment, albeit shorter. If I'm going to replumb I'd rather set things up so that bubbles only have to travel horizontally or up.

I see that now. I like your sketch much better!

It doesn't seem like a smaller eye is solving the issue. Flow drops about 3-4 gpm with the next size down. It does increase the velocity at the eye, pushing bubbles further into the pool, but doesn't prevent the accumulation of a bubble at the bottom of the cell.

 

[Newdude]

Dang it. Oh well, it was worth a shot before you cut pipe.

I’m still in the “there’s something else wrong” camp. 20-30gpm is a lot of water and a SWCG doesn’t make gas bubbles even remotely big enough to fill up the cell when you consider the rate and volume of water.

If this was a common occurrence, vertical kits just wouldn’t exist. Too much risk and no benefit.

I can't get past it either. I'm no genious, nor am I psychic, but still.

Beta, before you cut. Pull the cell and see if the fins are blocked. Maybe something came from the filter, or even faulty manufacturing and you didn't look closely enough at it with no reason to. Then rig up a gutter pipe or something to redirect the flow so you dont get soaked and fire up the pump on low to make sure its moving plenty of water at where the cell was.

 

[MITBeta]

I hear what you are both saying, and I will definitely follow your advice before cutting anything.

However, my observation is that the flow is essentially the same last year in the same pipe without the cell (maybe even a little higher given the early season clean filter). What it looks like to me is that there is not enough driving force to push all of the tiny bubbles created by the cell down against their buoyant force. Over a period of time, these bubbles coalesce and grow to form a larger bubble that sits at the bottom of the plates, or rises up against the flow on the outside of the cell where there is the lowest water velocity.

Here's another video:

I'd relocate the cell to the upflow side and let gravity do the work of keeping the plates submerged.

Here's another video:

OK I'm alot better now. in the first video the cell appeared empty like the bubble was stopping flow through the cell altogether. Err. Something else made next to no flow through the unit. The new video clearly shows plenty of water passing....until it doesn't I reckon.

One thing is for sure, you have single handedly silenced the I dOn'T nEeD a TiMeR crowd. I mean. You likely won't silence them, but 'how much gas can it possibly produce' has been clearly answered. And it's enough to *need* a timer.

 

[MITBeta]

I pulled the cell but didn't see any indication of a blockage or restriction.

 

[MITBeta]

So I went ahead and cut and glued the cell into a horizontal position:





I'm giving the PVC glue overnight to cure and I'll fire it up tomorrow.

 

[Texas Splash]

Look at all that room. Looks nice.

 

[MITBeta]

Ok, fired the cell up in the new position. There's still a bubble at low speed, however. Luckily it seems limited in size, but do I need to be worried about an explosion?

This week got away from me...

That small air pocket in the lower video shouldn't be a big deal. The plates look to be adequately submerged.

 

[Newdude]

I imagine that many have some degree of what you have going on. Pay close mind to it for now to ensure it doesn't grow.

Sub'd. I will be installing a similar set up for a family member so I can easily find it.
