Shipping & Freight

For an order containing products from a single brand, shipping is a flat rate based on your order total:

  • Orders up to $5,000: $279
  • Orders $5,000 to $10,000: $347
  • Orders $10,000 and over: $517

These rates cover standard freight delivery to a commercial address. After you place your order, our team will confirm your delivery timeline within 1 to 3 business days.

Ordering from more than one brand? Multi-brand orders ship on separate freight and are quoted individually rather than at the flat rate above. Place your order or contact us first and we will confirm total freight before anything is finalized.

Liftgate service is not included in these rates. If your delivery location has no loading dock or forklift to unload the freight from the truck, liftgate service is required and will be added to your shipping charge. If you are unsure whether you need it, contact us before ordering.

Commercial delivery locations are preferred when available. Residential delivery, limited-access locations, and appointment scheduling may affect handling.

Lead times vary by product, manufacturer availability, and selected options. Some configured, special-order, or non-stock items require additional processing time before they ship.

Please inspect all freight shipments at delivery before signing. If you see visible damage, note it with the carrier and contact us as soon as possible.

If you need freight, delivery, or lead-time guidance before ordering, contact our team before you purchase.

Compatibility / Fitment

Compatibility varies by product type, machine setup, selected options, and intended application.

For machine-mounted equipment and attachments, buyers should confirm fitment before ordering using the relevant machine information, including model, attachment style, mount type, coupler type, hydraulic requirements, and any other product-specific requirements listed on the page.

Hardscape Heavy can assist with pre-order fitment guidance based on the information you provide. This guidance is limited to purchase and compatibility review before ordering and does not include field installation, hydraulic modification, fabrication, or on-site setup support.

If you are unsure whether a product will work with your machine or application, contact us before placing the order.

Returns & Warranty

Warranty coverage is provided by the product manufacturer where applicable. Warranty terms, coverage periods, exclusions, and claim procedures vary by brand and product type.

Hardscape Heavy does not create separate warranty coverage beyond the manufacturer’s warranty unless explicitly stated on the product page.

Returns are governed by our store return policy. Because many products in this category involve freight shipping, special ordering, or configuration-specific selections, return eligibility may vary by product and condition. Special-order, custom-configured, used, damaged, or installed items may not be eligible for return.

Please review our full return policy before purchase. If you have questions about return eligibility or manufacturer warranty coverage for a specific item, contact us before ordering.

The Mi-T-M HG Series is a stationary natural gas or LP hot water pressure washer that runs off a building gas supply instead of a fuel tank to refill. It is built for a wash bay that draws on a steady gas line rather than refilling a tank between jobs.

A belt-drive triplex pump with ceramic plungers and a schedule 80 pipe-coil heat exchanger, backed by a programmable controller for auto start/stop and safety lockout, are built for continuous duty. It comes in two flow tiers, each wired for a specific shop voltage from 208V to 575V, single-phase or three-phase, so the model matches the electrical service on site as much as the flow needed. This is for a wash bay that runs hot water every day, not the occasional wash.

Common Applications

  • Continuous hot-water cleaning in a fixed wash bay
  • Facility washdown off a building gas supply
  • Permanent-install cleaning where a gas line is available

Selection Notes

  • Two flow tiers at 3000 psi: the HG-3004 models at 3.9 gpm with an 8.0 HP motor, or the HG-3005 models at 4.8 gpm with a 10.0 HP motor.
  • Match the model to your shop power: 208V, 230V, 460V, or 575V, single-phase or three-phase (see the model table for amperage). All models are wired for a permanent install.
  • The burner runs on natural gas or LP, vapor only; an LP conversion (HX-0105) and a 250 degrees F steam option are available. Plan the gas supply line and clearances per the install requirements.
