The on/off switch on my Jandy 400n heater seems to have failed. If I bypass the on/off switch, my heater works fine. What is the purpose of that switch, can you buy that separately from the gas valve? And is there any harm in leaving that switch bypassed?

My pool and equipment flooded and filled with a mass amount of dirt during the hurricanes last year, and I'm just getting around the fixing the pool heater, a Jandy JXI400. I got it working again, but now when running, it sounds like there is rocks inside of it. From googling, it sounds like...

I have a good foot or 2 of dirt in the pool from Hurricane Irene over the drains on the "surge" side of the pool. Any ideas how to get it out? I'm on the water, I'm worried about draining too much and having the pool pop out of the ground, I'm not much above sea level. I'd take pictures, but it...

Thanks for that advise, its a Jandy VS motor.... not sure the exact model number at the moment.

I do have a salt system as well that was submerged.

I haven't made it back home yet, but will be headed home tomorrow as power was restored today, but I live in Tampa. and I know my pool pump equipment pad did end up entirely submerged in sea water, from my understanding for about 3-4 hours. (Water has never come even close to the equipment in...

So I have a pool with an AquaLink RS where randomly, the SWG is not functioning, and there is no power/lights to any of the SWG components. It seems to turn on successfully every few days and works fine for a days, then back to not working again. Any ideas of what this can be? I tried pressing...

Thanks for the information! I'm gonna do my test, and if it turns out the Pentair is more accurate I'll probably try changing to the FloVis. This is a commercial pool, not a residential pool, AFAIK there is no requirement on residential pools and I've never heard of any sort of required...

Yup, but also part of why I want to look at it, is if there is ever a new inspector and he looks at the Pentair flow rate instead of the flow meter, he could shut the pool down based off of that, and I won't really have a good answer for them as to why thats wrong. Also, occasionally if someone...

Thanks, but the thing that irks me is its even more then 30 GPM difference, I'm looking at 55 GPM off. I'm a little confused by your phrasing, since you said the pumps fairly accurate (10%) then said the flow meter is 10% accurate which is extremely inaccurate, are you saying the pump is 90%...

Thats whats been happening, I was just curious about WHY there was a mismatch and if it could be corrected. The only "problem" is the number displayed on the screen, nothing else at all

I guess you entered my question, there is no real flow meter so the VSF flow rate is probably entirely inaccurate since its just based on RPM and presumably some flow restrictions? Sorry, forgot to mention this is a commercial pool, it has a required flow rate on the permit to be open. It has...

I'm sorry, it was a 3" pipe, this is the flow meter installed: https://www.amazon.com/gp/product/B007CU0QI2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 How does the pump automatically speed up as the filter gets dirtier if it doesn't have any built in flow meter?

Last year, in the middle of pool season, we a pump fail and need replacement and I had an Pentair Intelliflow VSF-XF 3 HP pump installed. When it was setup, the flowmeter after the pump on the return line to the pool was also replaced (2" pipe, 2" flow meter). From when the pump was installed...

I'll have to give the vitamin C thing a try and if not the Magic Stain Stain ID... I'm struggling a bit with why when I threw them in initially it cleared up an area but I can't repeat it now... My pool is marcite/plaster in ground, 2 hp pump, I'd guess around 20,000 gallons but I gotta...
