Is Rosemead water hard enough to soften?
It depends on your supplier. San Gabriel County Water District’s 2025 water quality report lists hardness from 17 to 200 ppm, averaging 97.4. On the U.S. Geological Survey’s hardness scale, 61 to 120 mg/L is moderately hard and anything over 180 is very hard. Homes billed by another company should check that company’s own annual report for the number.
Moderately hard water still leaves spots on glass, scale on shower heads and grit in the water heater. Whether a softener is worth it is your call; if you decide yes and the loop is already there, setting one up is a straightforward job.
How an install goes
Check the loop
We confirm the inlet and outlet, the shutoff, a drain point within reach, and an existing outlet for the control head. If any of those are missing, we say so before ordering anything.
Set and connect
The water is shut off, the old unit or loop caps come off, and the new softener goes in with a bypass valve, flexible connectors and the drain line clamped in place.
Program and test
We enter the hardness from your supplier’s report, set the regeneration time, load salt, run a regeneration, and check every connection for leaks.
Bigger jobs, free estimate
We install on an existing loop. Adding a new softener loop to the main line, re-piping, or adding an outlet is a bigger plumbing and electrical job with its own free estimate.
While we’re out for this, Rosemead customers often add water heater flushing, water heater repair, shower head and tub spout replacement or pressure regulator and expansion tank replacement.
What to text
A photo of the loop or the old softener, the pipes going in and out, the nearest outlet, and the softener model if you have already picked one.
Softener questions
Why does my water softener smell?
Bacteria in the brine tank or a softener that sits unused can cause odor. Cleaning the brine tank and running a regeneration usually clears it.
How much does it cost to install a water softener?
It depends on the unit and whether your house already has a loop. Depends on the job; we’ll let you know after we see photos. Tell us the model and we quote it.
How much salt does a softener use?
It depends on your hardness setting, household size and how often the unit regenerates. Moderately hard water needs less salt than very hard water. We show you how to check the level and when to top it up.
Will a softener help my water heater?
Yes. Softened water leaves less scale in the tank, so less sediment builds on the bottom. You should still flush the heater on the maker’s schedule.
Can you fix my existing softener instead?
Yes. Stuck regeneration, a salt bridge or a leaking bypass are often repairs rather than a reason to replace the unit.
Can you supply the softener?
Yes, or we install yours. You can buy the unit you prefer and we install it, or we can suggest a size that suits your household and water.
Do I need a loop?
Yes. Without one, the main line has to be cut and re-piped, which gets its own free estimate. Many Rosemead garages already have a loop from an earlier softener.
How do I set the hardness?
Use the number from your supplier’s annual report. We enter it and explain how to adjust it if you notice spots coming back.
What about the old softener?
We disconnect it and take it away, or leave it if you plan to sell or reuse it.
Does softened water go to the outside hose bib?
That depends on how the loop was plumbed. We check and tell you which faucets get softened water.
