Every firm listed here is in Vila-real. Near Castellón de la Plana itself, is Aquafiber Poliester Reforzado. For work that needs return visits, a firm within an hour’s drive is usually worth a slightly higher quote.
None of these firms has 20 Google reviews yet, so lean on references from past customers. Look at how recent the reviews are; a strong score from years ago says less than a steady run of recent ones.
Size a tank from your daily use and the longest dry spell you need to cover, then add a margin for deliveries. For drinking water, ask what the filter removes and how often cartridges or membranes need changing.
Questions to ask before you sign
- What size do you recommend for my use, and why?
- Is the tank food-grade for drinking water?
- What base and access does it need?
- What filtration do you recommend after a water test?
