I’ve finally figured it out why my heater, Pentair MiniMax NT, stopped working. It showed air pressure issue with blower motor running smoothly. I replaced the air switch and motor running cap; no luck. Finally, I decided to dig out the blower and took a look. Then I found out all of the fan...

This is the 2nd time my dolphin stops working in two years of service. It shows exactly the same failure as what I experienced last year. At that time the service center noted it was a bad motor and replaced with a new one. Unfortunately, my warranty expired last month. I open the unit and see...

There's an error LED flashes which indicates an air pressure issue. The blower fan keeps running at the low speed when the system is on, which is pretty strange. For a normal system, at the start up the blower fan should run at at full speed for 15s (pre-purge period), then slow down to half the...

Hello, I've updated my pool with the Pentair VSP. I'm wondering what is the right RPM for the solar panels. I read that one solar panel needs 3~4 GPM for the best heating efficiency, but how do I know under which RPM my pump can generate 40gpm given there are 10 solar heater panels? Right...

Hi Friends, I'm using an old 1HP SF1.65 3450RPM single speed star-rite pump (AO Smith motor SQ1102) for my pool and spa. The motor consumes 9.6A max at 230V. The pump runs great but it is noisy and consumes 1.8KW read from the electric meter. I would like to change to the latest VSP with as...

Hi Folks, Not sure if this is the right place to discuss... I ordered a robot cleaner which needs a power from the power center box. A licensed contractor installed a GFCI outdoor receptacle from the power center. The robot was plugged to the GFCI receptacle; it worked fine so far. I opened...

I’ve got a robot cleaner for a while. I don’t expect would go back to pressure side cleaner anymore. My PB said can take out the booster pump for free as I don’t use it anymore. Should I cap the inlet and the outlet after removing the booster pump, or connect them together? My PB said whatever I...

Hello Experts, I need to upgrade my single speed pump to VSP. The following factors weight heavily for the decision; 1) Quietness. My PB says the VSP needs to run at 2000 to 2400 rpm to pump water to the roof solar panels. When using SPA, need 3450 rpm. He said the latest VSP can be similarly...

Hi Experts, I need to change my power control center now, and I want to know which option should be the right way to go. My pool uses a single speed star-rite pump, with spa, a gas heater and roof top solar system. All old. They are controlled with Compool CP2000 indoor unit and an outdoor...

The cleaner has served my pool for a bit more than one year and finally failed. The power looks good, LED blinking as normal and I can even connect the robot cleaner on iPhone to setup clean cycles. Everything looks normal but cannot let it move at all, whatever by itself or by manual drive. The...

I wonder if I may change to a VSP but use it as a single speed pump, i.e. as a drop in replacement to the current single speed pump? I want to change to a VSP in seek for lower noise and electricity bill. However, my pool is quite old and comes with compool CP2000 control center and LX-10 power...

I'm currently using a very old single speed sta-rite 1HP pump. My concerns with it are the pump is pretty noisy and bears high electrical cost. My breaker panel shows 2KW when the pump is on. My pool is about 20K Gal, has a SPA which is about 2 feet above the pool thus needs to maintain a...

The waterfall from SPA to the pool barely flows while the pressure gauge reading is normal. I have a concern as the water flow rate for the SPA may not be sufficient. Interestingly, if I splash in the spa to help push more water a bit into the pool, or, a strong wind blows and excites a bit more...

Algae boomed days ago, shocked the pool and water has been clear now. But a large area on steps and wall are now shown green-yellowish algae stains, which cannot be brushed off. Any idea? Thanks.

The broken tile locates above waterline but unfortunately it's in the path of SPA-pool waterfall and it looks like water can enter the crack. The crack is about 1 inch long, 2mm wide. Any easy DIY fix?

Not sure if the thread is suitable for this session. Just wonder what do you use for fencing the pumps. An ideal fence should be 5'1/2+ tall to blocking the pumps from visual, easy to move for mechanic service yet steady enough to withstand strong wind, and if possible, block noise as much as...

I observed that my pool lose 3ppm chlorine every day. My pool has 10K gallons water and thus I'll have to drop 1 gallon liquid Chlorine every 3 or 4 days. It's 95F~99F outside everyday these days during day time and we use the pool three times per week.Does the CH consumption considered normal?

Just used for two weeks and seeing a lot of tiny holes on the DC power cord now. I guess squirrels or other rodents like to bite the cord. I used to leave the robot in the pool and now I have pull it out every day and save it in my garage. A lot of hassle... start missing my old Polaris 280 now...

Hi I want to replace the old fence surrounding the pool equipment to block them from visual. The fence guy asks if they can drill one foot deep hole on the cement, as shown in the photo below, to drop fence posts. I wonder if it would break any plumbing. My pool guy says should be fine but I'd...

My pool filter and plumbing worked fine without using the pool solar. I recently repaired the major leak of the solar and trying to use it. However, I noticed that once the flow control to be set to pool and solar, then turned on the pump filtering, the whole system started shaking strongly...

I expect heating efficiency would drop, but still like to double check if there's any other adverse effect, as the water would flow much faster under the same pump pressure. I have 9 Fafco water collector panels and 2 of them have major leaks and beyond reparable. I'm sourcing Fafco panels...

It'd be better to post a video while I don't know how to do so just past a photo here. There's a short 2mm wide crack locates at the inner side of the L junction, which is closed to another T junction. It's hard to cut and change the pipe here I suppose. I want to try a simple fix with roof...

Have a more than 10-year-old rooftop solar heater system, and hasn't run it for several seasons due to leaking. Recently I have started to think of repairing it. Ran it and found the following problems; 1) 4 or 5 Fafco collector panels (4'x10'x12") leak (9 in total), highly suspect racoons or...

I won't use my pool for swimming from Oct. to May next year. A pool guy told me to treat the pool as normal in the off season, i.e. 3 hrs pump running, add bleach and do weekly maintenance. No other special treatment needed as the local temperature never drops to the freezing point. Just wonder...

Hi just wonder how can I treat the pool wall stain, as shown in the attached picture. The stain cannot be brushed off. I have been running the cleaning robot 30min daily and brushing the wall weekly for a few weeks. Didn't get the condition improved. Highly appreciate if anyone could give an...

Hi I live in San Jose and thinking of buying a clear solar cover (bubble wrap) to help maintain my pool temp over night and block exessive evaporation. Did some research on web but still have some details cannot figure out; 1) My pool is in kidney shape. Should the solar cover be trimmed to fit...
