OATEY 35230 – Frequently Asked Questions

1) Can Hercules Haymaker descaler be used on a tankless water heater that feeds potable water?
Yes. The Hercules Haymaker descaler is safe for potable water systems, so it can be circulated through a domestic hot water tankless unit. It's citric acid based rather than a mineral acid, non-corrosive and VOC-free, which is why it goes into drinking water equipment where a muriatic-based product would not.
2) Will Haymaker descaler damage PVC, CPVC or rubber components in the flush loop?
No. Haymaker is compatible with most commonly found plumbing materials including PVC, CPVC, ABS, rubber, steel and most metals, so a typical flush kit (pump, hoses, isolation valve hoses, plastic bucket) handles it without issue.
3) Can I use Haymaker on an aluminum heat exchanger?
No, and this is the one to watch. Oatey states the product for descaling non-aluminum heat exchangers and water heaters. If the exchanger in the unit is aluminum, don't run this through it. Copper and stainless exchangers, which cover most residential and commercial tankless units, are the intended application.
4) Where does the used descaler solution go after I flush a tankless unit? Can it go down the drain on a septic property?
Haymaker is stated safe for septic systems and sewers, so the spent solution can be disposed of through the building drain on either a municipal or a septic property. That matters on rural service calls where a mineral acid descaler would mean hauling the bucket off site.
5) What kind of buildup does the Oatey Hercules Haymaker actually remove?
Carbonates, sulfates, phosphates, rust, oxides and other mineral deposits. That covers the hard-water scale that chokes flow and drives up firing time in a tankless unit, plus iron and rust staining in the exchanger passages.
6) Can I use the same descaler on a standard tank water heater, not just tankless?
Yes. Beyond tankless units, Oatey lists the Haymaker for descaling non-aluminum heat exchangers and water heaters generally, so a conventional tank heater with scale on the elements or in the bottom is a valid application. Same material compatibility applies.
7) Is descaling something to do on a schedule, or only when a tankless heater starts acting up?
Oatey positions the Haymaker to extend appliance life when used as part of a regularly scheduled preventative maintenance program, not just as a repair when flow drops or the unit starts short cycling. For a property manager running a fleet of tankless units on hard water, that means putting it on the annual PM calendar rather than waiting for the no-hot-water call.
8) How much descaler is in the Oatey 35230 bottle, and what does it weigh for a service van?
The 35230 is a 32 oz bottle of Haymaker descaler, listed at 3 lbs shipping weight. It's a liquid concentrate, clear in color. One bottle per flush is the usual way techs carry it, so a multi-unit property call means stocking one per heater.
