Lakeside homes get water from either Lakeside Water District or Padre Dam Municipal Water District depending on the address, and both deliver hard imported water that leaves scale in fixtures and heaters. Since we don't have a readable hardness figure for either, a test at your tap sets the softener. Call the number on this page to be connected with a local plumber in Lakeside.

Which district supplies my water in Lakeside?
San Diego LAFCO lists two retailers in the area. Lakeside Water District serves Lakeside, Eucalyptus Hills, Moreno Valley, Muth Valley and Wintergardens, while Padre Dam Municipal Water District serves other parts of Lakeside along with Crest, Harbison Canyon, Blossom Valley and Alpine. The boundary runs address by address, so check your bill. Lakeside Water District takes calls about water problems at any hour at 619-443-3805.
Does the local water change what I should buy?
Lakeside Water District's main supply is surface water treated at Helix's R.M. Levy plant, plus imported water from the Skinner plant and groundwater from the Santee-El Monte Basin, which the district treats at its Vine Street plant to remove iron and manganese. It disinfects with chloramine. The district's report includes a hardness row, but we couldn't read its values reliably, so we won't print a number. Padre Dam customers have a different report again.
The practical answer is a test at your faucet. A softener is the right tool for calcium and magnesium; it isn't a chloramine filter, so a carbon stage is the add-on if taste bothers you or if you want to protect the resin. Because the district already treats its groundwater for iron and manganese, a standard softener sized to your measured hardness is usually enough.
Will a softener fit an older Lakeside house?
Usually, with some piping. Lakeside's median home was built around 1978, and about 52.5 percent of homes predate 1980. Many have no softener loop, and the main may come in at the front or side of the house. The plumber cuts in a bypass and shutoffs, finds a drain for the brine line with an air gap, and makes sure there's power for the valve. On larger lots, splitting the irrigation and hose bibs off ahead of the softener saves a lot of salt.
A Lakeside note
Lakeside is unincorporated, so if the job needs a permit, it comes from the County of San Diego Planning & Development Services Building Division, which handles simple permits and inspection scheduling online. Sewered parts of Lakeside are served by the San Diego County Sanitation District. Ask the plumber where the brine line will discharge on your property before the install.
