I posted in January asking about repairing my expansion joint, long story short I never did anything about it. We had a lot of rain in SoCal last year and the expansion joint got worse with vertical displacement(1/2''in some areas)between the concrete deck and coping, seems like this was...

Just slammed my pool, Its my understanding that a high FC will cause inaccurate testing for pH, what level of FC will allow me to get an accurate test for pH? thanks, Brian

My pool already has some scaling but in fact I do not mind. My CSI is always within the levels suggested with Pool Math, before slamming CSI was .29 with the suggested range being no lower than -.6 and no higher than .6. Draining and refilling is a pretty big deal in SoCal because of the...

Due to medical issues I let my pool get out of control and want to get back on the right track. When I started the slam the pool was green with algae(pretty sure mustard) with FC 1 , CC 2, CYA of under 10, pH 8, CH 800(very hard public fill water), TA 130. The common way to lower TA as I...

My Hayward DE 4800 backwash valve needs replacing. From searching the net I believe Hayward SP0410X502S is the part # for this filter. There are quite a few negative reviews on this valve, mostly stating the steel slide in the valve fails due to substandard material for the environment(rusts...

I've watched a lot of youtube on the subject, asking here for anyone that has used a specific product. I DON'T want to use self leveling because some places have settled a bit and the surfaces are not on the same plane. Here is a seemingly good vid as far as application goes. He uses urethane...

I need to remove old expansion joint material at pool deck to coping and replace with new, suggestions on what to use are appreciated. thanks, Brian

thanks!

I need a Hayward DE 4800 filter tank cover o-ring and am having trouble finding one. I find a Hayward DEX2400K but it's not specifying it's for the DE4800, is this the correct one? thanks, Brian

Puzzled after reading this in the "CYA testing, further reading" section: Always round up to the previous line. If you saw the dot at 40 and not at 30 then you call it 40. First time I've seen this, why go to 40 if can still see the dot, why not use the 30 tested level to add cya amount as per...

Interested in getting opinions on this article/information, primarily cya levels and sanitation. https://blog.orendatech.com/five-things-cyanuric-acid

Thank you.

Thanks mknauss, re-read the article, aiming for 40ppm cya, I'll add the required amount of cya from pool math, wait a couple of days and see what it is then start slamming. Also I have a two speed pump, will the slow speed be adequate for running 24/7 during slam? thanks, Brian

Any reason I shouldn't add cya when I'm slamming? I've been slacking off on maintenance over the winter since we don't use the heater/pool and am opening it up now, cya levels are under 20ppm, slamming because I have algae . Also I have a two speed pump, will the slow speed be adequate for...

Thanks mknauss and Jim R, that sounds good to me, I'll start with the same run time, 6hrs, and see how it goes, less is more in this case. Seems like I read where I needed a longer run time with lower speed but I'm glad thats not the case. Thanks again.

Just installed a Pentair SuperFlo Pool Pump Dual Speed 1.5 HP(old Hayward 1.5hp single lasted lasted 15yrs). On the higher speed the pressure gauge at the filter(DE) is 15psi(same as my old pump), on the low speed setting it reads 3psi at the filter, does this about seem right? Filter info is...

Thanks guys , just ordered a Jandy.

I want to add a check valve to my system. Reading the reviews(amazon) both pentair and hayward have about 10% 1 star reviews, maybe they're cheap knockoffs bought online, not sure. Is there some brand(oem necessary?) or place to buy one that will last at least a few years. It seems like the...

I double checked and no energy rebates avail at this time. With either pump the outlet/inlet are 1.5", my lines are 2", I assume that using adaptors to 2"(smaller to larger) at the pump will not cause any issues. And yes COd3Sp4c3, I see the 2 speed pump does come with the switch so thanks for...

Yep SCE is pretty expensive. My reservations about the SuperFlo VS digital are based on: over a 10% 1 star rating on Amazon, customers saying it lasted only a few months, I'll be installing myself so 60 day warranty; my feeling digital is not as reliable as standard control, don't know if this...

Thanks Jim, I'm ignorant with regard to 2 speed motors! My confusion is with the pic I show of the toggle being wired in, if the black line is wired like shown in the pic, and coming directly from the load center(with no timer) then the toggle must be in the off(center) position for it not to...

Checked the rebates, Inteliflo VS $50 rebate if installed by "qualified" person, so thats $ loss, SoCalEdison where I live offers no rebates. I'll gather more info, seems like a higher than normal % of negative reviews on digital vs standard controls, such as receiving not working or crapping...

Thinking of getting this pump, 230v, it needs an inline switch at the motor to control the speed. Any reason I can't use it with my existing Intermatic mechanical timer, just wire it in one of legs? I only want to use the timer to turn on the low speed, when I need the high speed I can turn it...

Thanks, the Intelliflo at 3hp seems like overkill for my 15,000 gal pool, or can it be programed so it never uses the full load? The Superflo VS looks good, wondering of the use of the 1.5 to 2" unions(I have 2" plumbing) causes appreciable flow restriction. Also curious if the more basic 2...

Dang, just replaced bearings and seals on my Hayward Maxflo pump and then DROPPED it carrying it for installation....slightly tripped but thankfully I I didnt fall, only the shaft was bent, just enough so the impeller hits the shroud,will not freely spin. So here is what I'm considering, a new...

Great, thanks so much! I was just going to use the new ceramic part and the old other half but this is good news.

Replacing bearings(started getting very loud) and seals on a 14yr old Hayward Maxflo(I replaced all the seals about 7 yrs ago but not the bearings, everything went pretty smoothly until I tried to install the shaft seal(not the ceramic half) on the impeller, the interior diameter of the seal is...

I tried ordering a pump motor from Inyo and it wasn't a good experience, here's the short story. NO customer phone, only live chat, email, and fax. Live chat was anything but, took 35 min with up to 12 min wait between responses from them. The chat guy said I needed a different motor than I...

Thanks for replies guys!

Bearings need to be replaced or new motor, was running it 24/7 for 9-10 days(ending about 3 weeks ago) while treating pool for mustard algae(successful) during which time the pumped developed a small leak but is no longer leaking, thinking water got into the bearings then, started "screeching"...
