What it does

Same job as the standard Single Tank, sized up. A 12 x 52 inch tank holds a 2 cubic foot mixed bed of ResinTech CG10 softening resin and Jacobi catalytic coconut-shell carbon, rated at 64,000 grains. It softens and it filters: hardness, chlorine, chloramine, taste and smell, across the whole house.

The difference is capacity. A bigger bed goes longer between regenerations, which is what a busy household needs. Same BluePeak ProValve, same media and the same certifications as the standard tank. An undersized system is the most common installation mistake in this industry, and this is the tank that avoids it in a large home.

Who it is for

Larger households on city water: four or more bathrooms, or eight or more residents. A standard tank would be working at its limit in a house like that.

Below that, buy the standard Single Tank instead. Same media, same valve, lower price. The XL earns the difference only when the demand is genuinely there. Beyond it, for ten or more residents, a pool or continuous demand, the Dual Tank is the next step.

Questions about this system

What if I have a big household?

Standard tanks get outrun by high-demand households. Our Single Tank XL is built for homes with four or more bathrooms, or eight or more residents: a larger 12 x 52 inch tank rated at 64,000 grains, a third more capacity than the standard Single Tank, so it goes longer between regenerations. For ten or more residents, a pool, or a house that never really stops using water, the Dual Tank is the step beyond that.

Will this hurt my water pressure?

A properly sized system, no. An undersized one, yes — which is the most common installation mistake in this industry. Our systems are sized on service flow rate against your household’s peak demand. If someone quotes you a system without asking how many bathrooms you have, that’s a red flag.

Single tank or dual tank — how do I know?

It comes down to how much water you use and what is in it. Our Single Tank puts softening resin and catalytic carbon together in one mixed bed, which suits most city homes with up to three bathrooms, and the Single Tank XL is the same build sized for four or more. A dual tank gives each media its own tank — a softener tank plus a catalytic carbon tank on city water, or on a well, a softener tank plus an iron and sulfur tank. Continuous demand and harder problems push you toward dual. We size it off your test and your household, not your square footage.

What maintenance does the system need?

Whole-home tank systems are mostly self-maintaining — the valve regenerates or backwashes on its own, metered by your water use, and the media lasts years (calcite is the exception: it is consumed slowly and topped up). What needs regular attention: salt in the brine tank if you have a softener, sediment pre-filters, UV lamps annually, and RO membranes and filter stages on their cycle.
