Description
If your water softener brine tank is cracked, leaking, or just worn out — this is the straightforward replacement you need. This complete 15×36″ square brine tank comes fully assembled with every component included. Hook it up to your existing softener and it’s ready to run.
No hunting for parts. No separate orders. Everything is already in the box.
What Makes This a Complete Kit
A lot of brine tanks are sold without the internal parts — you get the shell and that’s it. This one is different. It comes with the safety float valve, brine well, pickup tube, air check, overflow fitting, and grid already included. That means you can swap out your old tank and get your softener back online the same day.
- Safety float valve — shuts off water flow automatically if the water level gets too high, protecting your softener from overflow damage
- Brine well with top cap — keeps the float mechanism clean and protected from salt buildup
- Pickup tube with air check — draws the brine solution up during your softener’s regeneration cycle reliably every time
- Brine overflow fitting — routes any excess water safely away from the tank
- Grid plate — sits at the bottom of the tank, keeping salt off the floor of the tank and preventing bridging
Built to Last
The tank itself is made from durable polyethylene — the same material used in most quality residential softener tanks. It handles salt exposure, moisture, and the natural expansion that comes with temperature changes without cracking or warping over time. The black color also helps prevent algae growth that can happen in lighter-colored tanks.
Salt capacity is 250 lbs, which covers most household softener setups without needing constant refills.

Who Needs This
Most water softeners have a separate brine tank that sits beside the main resin tank. Over time, these tanks crack, develop leaks at the fittings, or the internal float valve stops working correctly. When that happens, your softener can’t regenerate properly — meaning hard water starts getting through again.
This tank works as a replacement for most standard residential softeners. It’s also a good option if you’re setting up a new softener system and need a reliable brine tank to pair with your control valve and resin tank.
Frequently Asked Questions
Will this fit my existing water softener?
This is a standard 15×36″ square tank that fits most residential softener setups. Check your current tank’s dimensions and brine line connection before ordering to confirm compatibility.
Does it come with the safety float valve already installed?
Yes. The safety float valve is included and the tank is fully assembled — brine well, pickup tube, air check, overflow fitting, and grid are all in place.
What type of salt can I use in this tank?
You can use standard water softener salt pellets or crystals. Pellets are generally recommended as they dissolve more evenly and are less likely to cause salt bridging.
