The control box says the system is running, but the pool is cloudy, and the chlorine reads low. Or a Check Cell, Low Salt, or No Flow light won't go away. Or you are tired of buying chlorine and want to know what switching to salt involves.

Dog Days cleans and replaces salt cells, tracks down error lights, repairs the control side, and installs salt systems, including chlorine-to-salt conversions. A saltwater pool is still a chlorine pool: the cell makes the chlorine from the salt. When the cell stops keeping up, the pool goes cloudy, then green, like any other. About one in five pools on our routes runs on salt, and a few more have a salt system the owner decided not to fix.

The parts of a salt system, and what goes wrong with each

A salt system consists of a cell in the plumbing, a control box that powers it, and a set of sensors that determine when it's safe to run. A warning light can come from any of the three, and so can a pool that's short of chlorine.

The cell: scale, wear, and age

The cell makes chlorine by passing current through salt water across a stack of plates. Over time, those plates build up white scale, which cuts how much chlorine they make. Cleaning brings a scaled cell back. A worn-out cell doesn't come back, however clean it is, and needs replacing.

sensors

The sensors: salt, flow, and temperature

A Low Salt light isn't always low salt; it can be a dirty sensor or a failing cell reading wrong. A No Flow light can indicate a flow switch issue, or water that really isn't moving because the pump or filter has a problem.

The control box: power and settings

A blank display, a tripped breaker, a board that has failed, or an output setting turned down too low for summer. Sometimes the whole fix is a setting; sometimes the board has to be replaced.

Thinking of switching from chlorine to salt?

A conversion adds a cell to the plumbing and a control box to the equipment pad, then the pool is brought up to the right salt level. The water still gets tested and balanced like any chlorine pool, and the cell will need cleaning and, eventually, replacing. Larry will review your equipment pad and explain what a conversion involves at your house before you decide.

How a salt system repair works

1
call

1. Tell us the light and the symptom

Which warning is showing, what the display reads for salt, and whether the pool is cloudy or green.

2
science

2. We test the water ourselves

Salt, chlorine, and the rest of the balance, so we're working from real numbers, not the display.

search

3. We check the cell, sensors, and control box

Scale, wear, flow, power, and settings.

4. You hear the fix and the price

A cleaning, a part, a new cell, or a new system. Nothing gets done until you've said yes.

5. Running and producing

We confirm the system is making chlorine, set the output for the season, and tell you what to watch for.

How salt system work is priced

The first question is whether the cell cleans up. Larry answers it once he's tested the water and looked at the system. After that, the price depends on:

compare_arrows01

Clean or replace:A scaled cell that cleans up is a smaller job than a new one.

inventory_202

The system you have:Cells and boards are specific to the brand and model.

report03

The fault:A setting, a sensor, a cell, or the control board.

swap_horiz04

For conversions:The system you choose, the plumbing at your pad, and whether the pad needs new electrical work, which goes to an electrician we recommend.

receipt_long

You'll know the price of anything over $50 before it's done, and there are no hidden fees. Cells and control boxes under a manufacturer warranty are handled under that warranty's terms. Weekly customers' small wear parts under $50 go on the next invoice; everyone else approves every repair.

Salt system questions

?My salt system says it's working, so why is my pool green?expand_more
Because a cell can run and still not produce enough chlorine: it's scaled, worn, set too low for the season, or the pump isn't running long enough to keep up. The water needs a real test to find out which.
?What does the Check Cell light mean?expand_more
It usually means the cell is scaled, worn, or not reading the salt correctly. Sometimes cleaning clears it; sometimes the cell has reached the end of its life.
?The display says Low Salt. Should I add salt?expand_more
Test the water first. If the salt is really low, add it; if it isn't, the sensor or the cell is the problem, and adding salt will only push the level too high.
?How do I know if my salt cell needs replacing?expand_more
When a clean cell still can't keep up with the pool, it's worn out. Its age and the output it manages tell us, and we'll show you what we found.
?Do salt pools still need chemicals?expand_more
Yes. The cell makes chlorine, but the water still needs testing and balancing, and weekly customers with salt get exactly that.
?Can you convert my chlorine pool to salt?expand_more
Yes. Larry will look at your equipment and explain what's involved and what it costs before you decide.
?Can I clean the salt cell myself?expand_more
Some owners do, with the system switched off, following the manufacturer's instructions, and with gloves and eye protection, outdoors, because the cleaning solution is acid. Always add acid to water, never water to acid, as Hayward's manual puts it. If you're not sure how, or the scale is heavy, let us do it.
?Why did my salt system stop working after a cold snap?expand_more
Many systems cut back or stop producing chlorine when the water gets cold, to protect the cell. It may be doing exactly what it's designed to do.
