Covered except when swimming, so often that can be only an hour or 2 each day it's uncovered. But that doesn't seem to be enough, needs that good 24-48 hours of continuously uncovered to prevent or fix the hazy white. Definite chloramine smell whenever the cover comes off. It makes sense that...

Our pool has an opaque thermal foam pool cover (4mm sandwich of closed cell foam) rather than a translucent bubble cover. We keep the cover on 24 hours a day except when swimming (drought and water restrictions here). I have found that if the pool doesn't get much use in a given week, the...

Retested pH with Taylor and palintest, both agree around 7.5 - 7.6. Salt levels are fine (around 3300ppm using taylor). I will do an OCLT tonight, but I am wondering if this is a case where I should just go ahead and SLAM even thou there are no indicators for it. Is that a bad idea?

Tested using lab calibrated palintest photometer, high chlorine model (accurate up to FC 10). EDIT: Just checked FC and CC with Taylor, and confirms the photometer results. FC dropped to 2.5 prior to this. I understand you are implying CC may be the culprit, but if levels are < 0.5 then that...

Accidentally left the SWG turned up, FC went up to 7.5. Following the usual TFP advice I told the whole family it was fine to swim in, however all of us came out with irritated eyes. Never had this happen before at lower FC levels, all other params are fine. FC 7.5 CC 0.2 CYA 65 PH 7.6 TA 100...

The message is getting confused again here. This is not about running solar at a different speed (which any solar controller can do). This is about running solar at *two* different speeds. One speed to prime solar, then a second different speed to hold the solar at once it's primed. Afaik none...

I have been doing the bucket test with cover off pool, and after a 5 day period there is about a 1/4 inch difference. However the pool surface is exposed to different water currents, sunlight and wind conditions to the water in the bucket. So I'm thinking that may account for the difference? I...

The VRV can be in many locations, even just above the equipment pad. All it has to do is allow air in when under negative pressure so water can drain when the system is off. If it is functioning correctly and sealing (which mine is), the location has no impact on the performance of the system...

Water has to exit from the highest point, otherwise the panels don't fill unless you run them at a very high flow rate. I wonder if adding a constriction to the return pipe is an option? Yes it would increase tdh, but i guess the hope is by letting the panels prime at a lower flow rate, it is...

OK unfortunately my Easytouch and Intelliflo do not have that option of setting a higher solar prime speed. Other than added tdh, Is there an issue with just running the panels without full prime at their rated flow speed? In my case running at rated flow without prime still uses much less...

Managed to test some things. First of all I removed the VRV completely, and this made no difference at all to the pressure or bubbles in the returns. So its definitely not a VRV issue. Then I tried starting at panel rated flow speed, run for 30 minutes, then increase speed a little, wait 30...

I have an Intelliflo and it definitely doesn't reprime when speed switches, hence my issue with solar prime. I was thinking one solution may be to run a short scheduled program each morning after the main pump schedule is running. Just run 5 minutes at high speed with solar valve open, then...

I think the original question got lost here, I am curious because I have the same question. The goal is to have a solar priming speed that is different to the solar run speed. I.e: - when solar first switches on, run at speed X for 5 minutes to make sure the panels are primed. - after this...

Regarding the superflo, it can run on 110v I thought, so I don't quite follow what the issue is with power supply at your equipment pad? In terms of automation, yes you need to wire to mains and then use a low voltage cable to wire the pump to low voltage relays in the easytouch. Each pump...

The return side/filter pressure gauges are only showing the return side pressure. The total tdh as per the pump curves is the return side pressure *plus* the suction side pressure. The pump display has a readout of the total system psi (suction plus return). This value should always be larger...

There is no goal per se, just that the system tdh is the suction side pressure plus the return side pressure. The filter gauge gives you (approximately) the return side pressure, the vacuum gauge on the pump suction side gives you the suction side pressure. Once you have these 2 values you can...

The general idea is to run the pump at as low rpm as possible while still getting good skimming action and functioning equipment (chlorinators and heaters have flow switches and will only switch on at a certain flow speed). Then just increase/decrease the number of hours runtime based on what...

Cartridge filter is good for that size pool. You can never go too big with a cartridge filter. Heaters are highly specific to your climate and desired swim season length. Whomever is supplying it should be able to provide you with some data to show it works for your case.

To expand on that, it depends, but probably no. Most of the system pressure is likely on the return side rather than the suction side. So reducing suction side pressure won't help that much. But there is a way to tell for sure, you would need to put a vacuum pressure gauge on the suction side...

Just to chime in on the Intelliflo, I have one on a pool that's only 9,000 gallons. But what that means is that I can run it at very low speed and it uses barely any electricity, and is also pretty much silent. However the 2 setups you have proposed are both fine, and even the "basic" superflo...

To be clear you need an Intelliflo pump for automation. The superflo can't easily connect to automation systems (it's possible, but needs a bunch of custom relays and wiring kits, and is very bare bones control compared to the Intelliflo). Otherwise, looks like a good setup.

The automation *is* what let's you set it and forget it :) The main reason you need automation in a setup like yours is for flow speed control. It let's you set a very low normal flow speed (uses minimal electricity), and then have the flow speed automatically increase in response to events like...

Thanks for all the help @mas985 , I have some testing to do this weekend and will see what I can figure out. I'm assuming there is no magical device that lets me take non invasive pressure readings at various points in the system... I am limited to wherever there is a plumbing point I can...

Bubbles are definitely not from the SWG, I have tested in service mode with the SWG off and everything else off in the system, and still see the bubbles. They are only present when solar valve is on. Where you say "That would mean alot of head loss between solar valve and VRV", why is that the...

I will try to get some photos this weekend. It was installed by a professional installer who is certified for this panel brand. Was only installed a couple of months ago and has always operated this way. I asked about the high pressure when it first went in, and was met with indifference by the...

Filter pressure was 18 psi at 35 gpm. It just goes up and up as I increase pump rpms. VRV is on the supply side before both sets of panels. It is up on the roof at the lowest point of the panels. The VRV seems to just be threaded in. Is it safe to unscrew it and screw in some kind of end cap...

Each panel is 6.5ft x 4ft, so they are fairly small panels. And the fact that they are split into 2 separate arrays connected in serial means the net flow rate is low (7 * rated panel flow instead of 14 * rated panel flow). - At rated speed (3.5 gpm/panel as per above), there is a minor amount...

If you search the web there are a number of home automation projects floating around that have pentair rs485 protocol support. For example nodejs-pentair

Fwiw my Intelliflo VSF has over pressure detection and will switch itself off if system pressure rises above a configurable level. I assume this is a feature only available on the VF or VSF pumps and is using the flow rate pressure sensor.
