Sioux Chief 963-HTL-FE FloweasyDrain Opener, Virgin Sulfuric Acid Formula, Case of 12

The Sioux Chief FloweasyDrain Opener is an instant-acting chemical drain opener formulated from virgin sulfuric acid with twelve buffers and inhibitors, made in the USA and sold only in full case quantities of 12 EA. The FloweasyDrain line is available in Ounce and Quart bottle sizes, giving plumbing contractors and maintenance crews the option to stock smaller touch-up bottles or full-strength quart bottles for heavier clogs, depending on the job at hand. Across both bottle sizes, the formula is engineered to clear clogged drains, cleanouts, sinks, and toilets without harming metal piping, PVC pipe, or septic systems, making it a fast-acting tool for rough-in and service calls where standard mechanical clearing is not practical. The formula heats up slowly to temper toilets and can be poured directly into standing water, a feature that sets it apart from typical consumer-grade drain openers while remaining manageable for professional use on the jobsite.

Key Features

  • Available Bottle Sizes: Offered in Ounce and Quart bottle options to match the scope of the clog and the volume of product needed per application.
  • Case Packaging: Sold only in full case quantities of 12 EA, suited to stocking service trucks or supply houses rather than single-unit retail sale.
  • Virgin Sulfuric Acid Formula: Contains virgin sulfuric acid with twelve buffers and inhibitors, delivering strong clog-clearing performance while moderating the reaction across every bottle size in the line.
  • Pipe & Tank Safe: Will not harm metal, PVC pipe, or septic tanks, making it safe to use on all common drains, cleanouts, sinks, and toilets found in rough-in and finish plumbing systems.
  • Controlled Heat Reaction: Heats up slowly to temper toilets and can be poured into standing water, reducing risk of cracked porcelain or splash-back compared to faster-reacting formulas.
  • Professional-Strength, Consumer-Safe: Positioned as the only instant drain opener strong enough for professional use while remaining safe for general application on common fixtures.
  • Made in USA: Manufactured domestically, supporting consistent sourcing and quality control for Sioux Chief's plumbing supply line across all bottle sizes.

Sioux Chief 963-HTL-FE20 – Frequently Asked Questions

1) Is FlowEasy drain opener safe to use on PVC pipe and a septic system?
Sioux Chief's FlowEasy drain opener is formulated not to harm metal piping, PVC pipe, or septic tanks. The virgin sulfuric acid is treated with twelve buffers and inhibitors, which is what lets it run through common drains, cleanouts, sinks, and toilets without attacking the pipe. That makes it usable on a septic property where a straight acid product would be off the table.
2) Can I pour FlowEasy into a toilet that is already full of standing water?
Yes. The FlowEasy formula heats up slowly to temper toilets and is made to be poured directly into standing water, so you do not have to bail the bowl or the sink first. The slow heat ramp is there to reduce the chance of cracked porcelain and splash-back that comes with faster-reacting acid openers.
3) Will FlowEasy open a floor drain or a cleanout, or is it only for sinks?
It is used on clogged sink and lavatory drains, blocked toilets, and floor drains and cleanouts. For a facility crew it is the chemical option when running a cable or a jetter is not practical, such as a drain under a finished floor or a cleanout you cannot get a machine to.
4) Is FlowEasy drain opener made in the USA?
Yes, Sioux Chief's FlowEasy drain opener is manufactured domestically, with United States listed as the country of origin. That matters on government, healthcare, and education purchases where domestic sourcing is a line item on the PO.
5) Is this a consumer drain cleaner or a professional-strength product?
FlowEasy is a professional-strength instant-acting opener built on virgin sulfuric acid, but the buffer and inhibitor package keeps it usable on common fixtures. It is positioned as an instant drain opener strong enough for professional service work while staying safe for general application on standard drains and toilets. Handle it as an acid product regardless, with gloves and eye protection.
