Adjust the pH into range first.

Why run 24/7 ???????????????????

Just to filter. My CalSpa is a 1988 model, and I always had issues with its factory filter cartridge housing leaking, plus the big plastic "nut" kept breaking and was at least $20. Plus access to even remove the housing was ridiculous. So I routed the plumbing out of the cabinet, with shut off valves on both sides of the filter, and used an aftermarket Hayward filter unit which seals at the top. I cover this all with a wooden box I made, not in the photo.

I have a spa filter I routed outside of my spa cabinet, has worked fine for a decade now.

I would think so.

Many spas have a flow sensor to prevent electricity from getting to the heater element if the flow is too low, for safety.

I'm responding, even though the poster did not start his own thread. purchased a Doughboy brand above-ground pool liner for my 15' pool and had it professionally installed (installer said Doughboy was best). Same installer as 14 years earlier when entire pool was installed. Within a month I discovered a leak at a seam, a bad seal in the manufacturing process. Doughboy wanted me to cut out the area with the leak, and also the area with a Sharpie-written manufacturing number, and ship that to them for evaluation (10 year warranty or so). Well, that was obviously out of the question (I could put a pencil through the hole), and they would not accept a local Doughboy dealer's opinion either. Finally after fighting for 2 months (and doing a home-made patch), I told them that I would just post the facts everywhere on the Internet, and Doughboy realized that loss of even ONE pool sale would be worse than replacing the liner. So they agreed to send a new liner if I would pay shipping, and I reluctantly agreed. Well, that liner has been in a closet now, and I've got apparently leaks in 2 other places, so that newer liner might go in next spring, and I'd try doing that myself. Believe me, sad that sometimes one has to complain a bunch to get action. UPDATE 2021: In April 2021 I needed to drain the water and planned to fix those two leaks, but when mostly drained a windstorm came up and damaged my pool structure and tore the old liner to shreds. So a week later, my daughter and I installed that liner that had been in my closet, my first install, took us 3 hours and 3 upright posts needed to be shortened due to rust from leakage/damage.

My 7-foot 1988 CalSpa holds like 300-350 gallons. I use a floater and 1" bromine tablets, my floater holds like 7 tablets. I keep pH in the range. Once every week or two I use some monopersulfate shock. I don't use any other chemicals except use a leak sealer product like every two years, as I have a yet-undiscovered leak not in the equipment section.

Yes. And post pictures !!!

Ha! Try submitting an E-mail question for a 1988 spa. You won't think nearly so highly of them

That looks like a simple flexible PVC hose with hose clamps on each end. Hardware store, Home Depot typically sells in coils or by the foot. My own CalSpa is way older than yours, doesn't have a similar hose, so can't tell you where it goes.

First of all: what's a "C pipe" ???? Got a picture of yours, and the flattened area? Because may cause more trouble than it's worth to "fix" it.

Sounds like it's picking up a short to ground (like its GFCI is operating properly to protect you) or its GFCI is malfunctioning.

My 1988 CalSpa is still operating.

If you backwash, does the pressure drop or stay high???

I've had a 15-foot non-inflatable above-ground pool for 21 years now. Mine came with a real pump and real sand filter. I've had the liner replaced twice in that span, once by the original installer and then in April with the help of my daughter. No, I only brush or vacuum it every few weeks. Vacuuming such a small pool takes under 15 minutes. I use a floater/chlorine dispenser. I superchlorinate every few weeks, or use monopersulfate shock.

I just use outside speakers on the patio wall, wired from stereo inside.

My current cover came from a local pool supplies store that had about a dozen assorted covers stacked in the back of the store, and at a real good price. One was exactly what I needed (had a big manufacturer's name on it), so I bought it and threw it into the back of my truck. This was about 6 to 8 years ago though, and that store is no longer in business. Prior to that, a local cover company made cover for me (Phoenix AZ).

Yes, not too uncommon. I should tell how Doughboy kept trying to weasel out of replacing my 1-month-old liner for my 15 ft. round pool, installed by a professional pool installer !!! They would not accept one of their local dealers to inspect the pool, wanted parts of it shipped back to them at my cost, then I should wait 3 weeks for their "decision". I told them I'd just post the truth of what happened and how I was treated online everywhere I could. No Susan -I don't have a cover lift, just a pair of bent metal cover holders that hold the cover up. I bought this like 20 years ago; may not still be commercially available.

I've seen white pools, and the water still had a slight blue tint (think of lakes and the ocean). So I think it's esthetically pleasing for folks to see blue color. Both my above-ground pool and my old spa are blue.

I'm in Arizona, have had my CalSpa since 1988. My 7-foot spa is on my 8-foot covered patio, so doesn't get full Arizona sun in the warmer months, shielded by the patio roof. So in those 32 years I've gone through at least 4 covers. The sun is way worse than the air temperature, but a cover in the sun gets quite hot. I've never tried a protective product on mine. Right now my cover "probably" needs replacement due to the seam starting to show wear. I've had longer cover life in the last 15 years once I installed cover holder so I can fold back rather than lift the awkward cover off and put on the patio.

Yep, cost $3000 then, CalSpa Hawaiian.

Similarly, I buy 5500 watt heating elements for my 1988 CalSpa from Home Depot or Ace Hardware, considerably less than from spa dealer.

$170 to fix is not a ton; consider that a new cover could be $400....
