Lana I'm still not sure if I've got the results I'm hoping to see. We've had a few storm fronts through my area in the past few weeks but I have not felt a need to use a net to get stuff off the surface so perhaps I'm overly concerned. My three return outlets are the eyeball type and I've got...

With my new WFE-3 up and running, I need to approach the proper orientation of my return 3 1" return eyeball outlets. I'm getting (as near as I can tell) excellent flow from all, based on the amount of movement from the "far end" outlet. My pool is rectangular 16 x 34 and all of the return...

Back in business Picked up a fresh set of CH and TA (Leslie's has a coupon for 50% off)...all of mine were 3+ years old. Used the procedure of adding 5 drops of 0012 before proceeding with the normal test and got a good blue at 35 drops (albeit with red specs). Getting the 5 drops of 0011L to...

Response from Taylor Here is the full text of the reply message from Taylor. I've made bold the portions of major interest. Bottom line: 1. The red specs are magnesium and are normal, more normal in some waters than others. This was mentioned in an prior reply to this thread. 2. You can try...

Still getting a precipitate in the test Tried the Taylor suggestion of adding 5 drops of R-0012 to the sample before adding 0010 and 0011L. Did get a more bluish end result but still got the red particles. Let the solution sit for a bit and the red stuff settled to the bottom of the sample...

Thanks Mark, Thanks for the formula's and also for all the help. Without you and the other folks here I'd be at the mercy of some bone-headed tech. Based on the math I've got around 39 feet of head, so I figure I'm somewhere around 70 GPM with puts me a 6 hours for 1 turn per day. (Your...

I just performed the Taylor Calcium Hardness test (the blue top bottles) and got a strange result. The solution turned red as expected after 20 x 0010 and 5 x 0011L. After adding about 35 drops of 0012, the red started to precipitate into small globs that remained in suspension while the...

Success (sort of) Got the valve installed this morning. UPS didn't show up until around 5:30 yesterday...I must be one of their last stops. I seem to get the best balance between impeller noise and pipe noise with the Jandy about 1/3 of the way closed, with the suction side Jandy balanced to...

Eyeball fittings Mark The Jandy valve has arrived at the UPS South City location and will be here probably tomorrow afternoon (I very seldom get a morning delivery from them for some reason). Rather than running back and forth to the pool store trying to get the head required from smaller...

More readings With the end of line eyeball re-installed and the cleaner shut off, I get 13 in HG at the pump and 6.5 PSI at the filter. Here is a diagram of the piping and fixtures: Here is a table with the fitting count and pipe runs: Hope this helps some. Rich

OK, so a vacuum gauge from Leslie's Pool is now installed where the drain plug was located on the strainer housing on the Whisperflo. The vacuum is hovering around 9 HG. The pressure gauge on the filter is a hair under 8 PSI. The needle on the vacuum is fluttering a tiny bit which I assume is...

Vacuum gauge readings So, if I can find a vacuum gauge I suppose I want one that reads out in PSI. I noticed one made by American Granby at Amazon for not too much money. It reads to 30 PSI (although the text says 30 HG). I believe I would want to be sure my discharge side PSI is higher than...

Scott Good to know and thanks. Living in the SF Bay area, one tends to forget about winterizing. Rich

The fitting in question is from Pentair and is a PVC male slip connection. I've seen others by other makers that are threaded male. The pool company that did my rebuild simply cut the 1-1/2" PVC off flush with the plaster and shoved the fitting into the pipe. The retaining nut operates as...

Suction side readings Mark, Is there an easy (and not too expensive) way to plumb in a vacuum gauge on the suction side? If so, would it be worth it to help keep my suction/discharge head in balance? As for your model, remember that they are only to approximate or predict reality, not to be...
