Hot Tub Cleaning Is More Than a Drain and Refill.
We purge the jet plumbing, scrub the shell, and rebalance from fresh water. That is the cleaning that actually resets a spa.
How Often the Water Really Needs Changing
There is an actual number for this, and most spa owners are surprised by how small it is. Take the gallons your tub holds, divide by the number of people who soak on an average day, then divide by three. That is roughly how many days the water has left before it is spent. A 400-gallon spa that two people use every evening is done in about two months, not the six or eight that people tend to stretch it to. Good hot tub cleaning is not something you book when the water finally looks bad. By the time it looks bad, you are months overdue.
The reason the interval runs so tight comes down to volume and heat. A spa holds a fraction of what a pool does and sits at 100 to 104 degrees. Every soak adds sweat, lotion, deodorant, and skin cells to a small, hot, heavily jetted body of water. Sanitizer burns off quickly at that temperature, and dissolved solids keep climbing until no reasonable dose of chlorine or bromine can stay ahead of them. That is the point where the water starts to feel off no matter what you pour in.
Tell us how often you use it and we will set the right cleaning interval.
Schedule a Spa Drain & CleanThe Real Work Is in the Plumbing
Drain a hot tub, wipe the shell, and refill it, and you have done maybe half the job. The half that matters lives in the pipes. Every spa pushes water through several feet of hidden plumbing to feed the jets, and that warm, dark, wet run of pipe is exactly where biofilm sets up. Biofilm is a bacterial layer that grips the inside of the lines and shrugs off normal sanitizer. It is what feeds Legionella and Pseudomonas, and it is usually why a freshly refilled tub clouds over or foams again within a week.
So before we drain anything, we run a line-flush purge through the circulation system and let it work the jets. It breaks the biofilm loose so it leaves with the old water instead of seeding the new fill. Then we drain fully, hand-scrub the shell and waterline, and pull the cartridge. Spa filters are smaller and pack tighter than the cartridges in a pool filter, so they load up faster and sometimes need replacing rather than another rinse. We check the housing and the pump basket while everything is open and easy to reach.
Why Hard Water Is Rough on a Spa
The tap water across Riverside County runs high in calcium, and a hot tub punishes that harder than a pool ever does. Heat drives calcium out of solution, so it plates onto the hottest surface first, which is the heater element. Scale on the element makes the heater run longer for the same temperature, and a scaled element is the most common reason an older spa heater gives out early. You see the rest of it as a chalky white line at the waterline and a gritty roughness around the jets.
That is why we test calcium hardness on every visit, and why a fresh, balanced fill protects spa equipment more than it ever needs to in a pool. Starting from clean water is the cheapest insurance the heater and pump will get. When scale has already built up, we work it off the shell and fittings during the drain, while the tub is empty and we can actually reach it.
Spa Questions, Answered Straight
How often should I drain and refill my hot tub?
Use the soak-ratio rule. Take the gallons your spa holds, divide by the number of people who use it on an average day, then divide by three. That is roughly how many days the water has. A 400-gallon tub used nightly by two people is spent in about two months, not the six or eight most owners stretch it to.
Why does my spa water foam or smell even after I add chemicals?
That is almost always biofilm in the plumbing or dissolved solids that have climbed past what sanitizer can manage. Both live where chemicals cannot reach them well: inside the jet lines and throughout water that is simply worn out. A line purge and a fresh fill fix what another dose of shock will not.
Can you clean the spa on the same visit as my pool?
Yes, and most of our spa owners have us do exactly that. Folding the hot tub into a regular pool visit means the chemistry gets checked on a real schedule instead of whenever the water starts looking off, which is the single best way to stretch the time between full drains.

“Our hot tub had a weird smell and cloudy water no matter how much shock we added. They did a full drain, cleaned out the biofilm, and it has been perfect since.”
“They cleaned the filters, purged the jets, drained and refilled. The water is clearer than the day we bought the spa. We use it every night now.”
“I did not realize how much buildup was hiding in the plumbing lines. After their deep clean, the jets run stronger and the water stays balanced longer.”
“Hot tub had foam on the surface that would not go away. They drained it, flushed the lines, deep cleaned the shell, and refilled with fresh water. No more foam.”
“The spa filters were so clogged the jets barely worked. They replaced the filters, cleaned the pump basket, and the water flow is back to full strength.”
“We use our hot tub every night and it gets dirty fast. They set us up on a monthly deep clean schedule and the water stays clear and balanced between visits.”
“Calcium buildup along the waterline was making the spa look old. They scrubbed it all off during the cleaning and it looks brand new. Really impressed.”
“Our spa sat unused for six months and the water turned murky. They did a complete purge, drain, and restart. Crystal clear water and ready for guests that weekend.”
