What water work costs in San Antonio
The national range is from the site’s cost guide, checked 2026-11-08. The local column applies the 1.00× metro factor and rounds to $5. It is a planning band, not a quote.
| Job | National range | San Antonio planning band | What it includes |
|---|---|---|---|
| Whole-house softener, installed | $2,500–$6,000 | $2,500–$6,000 | Typical US range |
| Whole-house filtration | $3,500–$9,000 | $3,500–$9,000 | Typical US range |
| Well tank replacement | $1,200–$2,800 | $1,200–$2,800 | Typical US range |
| Well pump replacement | $900–$2,200 | $900–$2,200 | Typical US range |
| Reverse osmosis, installed | $3,500–$8,000 | $3,500–$8,000 | Typical US range |
| Annual service, no salt | $150–$400 | $150–$400 | Typical US range |
Editorial metro factor, not a measured price index. The factor is not a measured local price index; it estimates labour and permit overhead. A quote that is far below the band usually has a smaller scope, not a better price.

Firms in San Antonio, TX are shown in the order supplied by the dataset, not by rating or payment. No placement is sold. Each name opens that firm’s own profile page.
How this list was built
The directory starts from public business records: the firm’s own website, its published address and phone number, and the state or city licence register named above. A record is marked verified only when a person has checked the name, address, phone and licence against those sources and recorded the date. The place_id field is kept so a future rebuild can match the same entity without guessing.
The national cost band comes from the site’s cost guide. The metro factor is an editorial estimate, not a survey. No rating, review text, price or availability is invented for a verified page; where a public rating is shown it is attributed and dated.
If a record is wrong, the firm can ask for a correction or removal.Corrections: contact@watertreatmentpro.com. Read the fulllisting verification method.
