The DI Saver replacement hub fits both the water-powered and the 110V H2Pro RO/DI carts. It is a serviceable component, so you can replace a worn hub and keep the cart working.
Check your cart before ordering: the hub is not compatible with Rival carts, which take the Rival V2 DI Saver upgrade kit instead.
The hub ships with 10' of 1/2" plumbing line and lubricant, so everything needed for installation comes in the box.
Use the lubricant on the hub's O-rings so they seat without forcing them into the housing. Then reconnect the RO and DI lines, and test the valve in both positions before going back to work.
The DI Saver is a 3-way valve: turn it to RO and the water bypasses the DI filter. The Rival V2 kit adds it to a Rival, and the H2Pro hub replaces it on either H2Pro cart.
Use RO-only water where it does the job, test RO output, or bleed off high-TDS water before it reaches the DI. Less water through the DI means resin lasts longer.

Both H2Pro carts, water-powered and 110V. It is not compatible with Rival carts; a Rival takes the Rival V2 DI Saver Upgrade Kit.
The 4-Stage Upgrade Kit includes its sediment and carbon filters, the stainless Carbon/DI housing a new filter cartridge, the stainless RO housing a new RO membrane, and the H2Pro hub 10' of 1/2" plumbing line and lubricant.
No. Tucker says the hardware holding your current carbon pre-filter bracket holds the new bracket.
It is a 3-way valve. In the RO position the water bypasses the DI filter, so you can use RO-only water, test RO production and bleed off high-TDS water to save DI resin.
Yes. The stainless Carbon/DI housing is sold as a Carbon or a DI variant; order one of each to convert both stages.
