Hi LB, I did use a 1.5" to 2" bushing to go from my 1.5" intakes from pool. I had to modify the 2" street elbow to get it to fit into the Jandy valve. The intake pipes were too close together and of course set in cement. But I was able to shave off part of the street end to get it to fit...

Ok so I re-plumbed the suction side. I went from the existing 1.5" verticals to new 2" and was able to run that into my new Jandy diverter and then into a Jandy check valve. This eliminated 8 elbows to only one 2" elbow. Plus it eliminated the crappy Ortega 1.5" valve, replaced, to a Jandy...

Mark: Thanks for the reply. Priming RPM is 3450. Both suction ports are open but they go through an Ortega 3-port valve which severely reduces flow. All of those elbows can't help either. I had pressure at both RPMs mentioned and through that range. And I'm assuming that pump side leaks don't...

Ok.Thanks. Do you guys figure that a leak at the shaft gasket or motor seal plate would affect vacuum as well? That kind of makes sense to me.

I called Pentair they are going to send someone out. I did read that some people have had small suction side air leaks worsen after new pump installs. Makes sense. My old pump was a WhisperFlo 1.5HP 1.47 SF so it was definitely pulling. I had some air in the basket but nothing major. Maybe the...

Hi Guys, I just installed a new Pentair IntelliFlo XF pump station. It doesn't seem to be priming properly. The basket does not fill all the way up with water.It fills to the top of the basket after much "work". So like an inch from the lid - one heck of a bubble. :-D I saw here at TFP the...

I'm trying to get a handle on how to most efficiently run my 2010 Jacuzzi J-480 Spa. California electricity costs are killing me. First I want to know how much power the Spa uses. I know from the manual that the max draw for the motors, radio, and Ozone is 3.8kW. It would be helpful to know...

Thanks Richard. I did mean -0.6. Also, I'm very impressed with your breakdown of pool chemistry. No matter where on the web I look the references always seem to come back to TFP, specifically referring to your explanations. It's been fun geeking out on pool chem. So thanks again to you and TFP...

Ok I think I understand. Thanks. I found the following information from the U of Arkansas. "Temperature Counter to the typical increase of mineral solubility with increasing temperature observed for most minerals, many carbonate minerals are more soluble in cold water. For example, the Ksp...

I'm curious about the CSI. It's cold here in Northern California or at least it hasn't warmed up yet. My pool is 50oF. It appears from using the Pool Calculator that temperature greatly affects the CSI. Or that CSI decreases with decreasing temperature. This seems counter intuitive to me as I...

Ok so I'm in the process of cleaning the finger elements of my Pentair FNS 60 and I might be having some problems. The last time I did this a week ago(pressure increase from all the dead algae has been happening quickly and I don't have a multi valve for back washing) I noticed that the...

Thank you for all the great advice and support. Sorry. I do get ahead of myself and I'm bad I helping myself. And I got excited and just through everything in at once and then scrubbed the pool for 3 hours last night to midnight. The pool light was particularly helpful and motivating as it...

Ok right. Baking Soda raises TA. Thank you. I added Borax to get me to 50ppm Borate. But since I was low on TA(40ppm) and pH(7.2) I knew I shouldn't add a comparable amount of Muriatic Acid to counter the affects of the Borax. So, I'm planning on adding 2.5Gallons of 34% MA followed by 135oz...

Aha, I think I'm excited to post in a forum. I don't do that ever. I'm just realizing that the Pool Calculator tells me what happens when I add any chemical. Not just Chlorine. Amazing. Looks like the Borax will add 115ppm TA and 6.4pH which puts me at 155ppm and 13.6pH respectively. So I can...

Love this site. Just getting started with BBB. Got my TF-100. Specifically purchased from NC despite living in CA because I wanted to contribute. Started with a green swamp. Drained 75% of water to reduce my 100+ppm CYA. Refilled, brushed, changed cellulose fiber on my Pentair DE three times...
