What Cheval Plumbers Get Wrong on Well-Water Tankless Math
Cheval (ZIP 33558) is a gated 1990s and early 2000s golf-community build off Lutz-Lake Fern Road where many Cheval West, The Estates of Cheval, and Cheval Polo Club homes pull from private deep wells running 12 to 15 plus grains of hardness, which scales tankless heat exchangers within 18 to 24 months if not pre-treated. Original high-end equipment installed in the 1990s buildout is now at end-of-life across whole streets at once. We size your Rheem unit against actual fixture-unit demand under WSFU calculation and engineer the softener + tankless package so heat exchanger scale failure is not in your future.

What Makes Cheval Water Heater Installation Different
Pre-Softener Treatment for Well-Water Tankless
Cheval well water at 12 to 15 plus grains will mineral-scale a tankless heat exchanger in 18 to 24 months without proper pretreatment. We install a properly sized whole-home softener upstream of the Rheem Performance Plus tankless, with bypass for hose-bibs to keep softened water out of irrigation. Scale-prevention adds about $1,400 to $1,800 in equipment but extends tankless heat exchanger life from 5 to 7 years (scaled) to the full 18 to 22 year design life.
Well water 12+ grains scales tankless heat exchangers in 18 to 24 months untreated.
Well-Pressure-Tank and Bladder Integration
Cheval well systems run a captive-air pressure tank with a typical 30-50 psi pressure switch range. The Rheem Performance Plus tankless needs a minimum 25 psi inlet pressure and a stable 30 psi minimum during firing or it will nuisance-lockout. We measure the pressure tank pre-charge during the FREE estimate, verify the pressure switch range matches Rheem spec, and recommend a constant-pressure pump upgrade if your switch cycles too aggressively for tankless to fire smoothly.
Tankless needs 25+ psi inlet, 30+ psi during firing for stable operation.
Expansion Tank Sized for Closed-Loop Well System
Well systems with a check valve at the pump head create a closed-loop pressure system identical to municipal-with-backflow. Without a thermal expansion tank, every heat cycle pushes water pressure against the well pump's check valve until the heater's T and P relief opens. We size a 4-gallon thermal expansion tank for 50+ gallon Cheval heaters, pre-charged to match measured static well pressure. Without it, expensive cycling damages both the pump and the heater.
Well system check valve creates closed-loop; expansion tank prevents pressure cycling.

I had a great experience with Alejandro from Home Therapist Cooling, Heating, and Plumbing. He repaired two toilets and installed the water line to my new refrigerator after the delivery team refused to connect it due to the existing plastic line.Alejandro truly went the ext...

Tankless Without Softener = Warranty Voided
Rheem manufacturer warranty on Performance Plus tankless explicitly requires water hardness below 7 grains for warranty coverage. Cheval well water at 12 to 15 plus grains voids the heat exchanger warranty if installed without softener pretreatment. We size and quote the softener as part of the tankless install package and register the warranty for you. Without softener pretreatment, scaled-out heat exchangers fail in 5 to 7 years and you eat the cost of a $1,800 replacement.
Call (813) 343-2212 for a FREE in-home estimate. We will test your well-water hardness on site and engineer the softener and tankless package to preserve your warranty.
