A Jackson drain water tempering kit is a plumbing device, not a food or drink recipe. It mixes hot wastewater with cold water before discharge to help control the outlet temperature; the correct kit, installation, and settings depend on the specific dishwasher or other equipment and local plumbing rules.
Ingredients
- 1 Jackson drain water tempering kit (the exact model specified for your equipment)
- 1 compatible drain hose or outlet connection, sized to match the equipment and kit
- 1 cold-water supply connection, only if required by the kit’s instructions
- 1 approved pipe clamp or fitting for each connection, as specified by the manufacturer
- 1 suitable thermometer for checking discharged water temperature, if the manufacturer or local code calls for it
- Equipment installation manual and the tempering kit’s model-specific instructions
Instructions
- Identify the equipment and kit model. Read the equipment nameplate and the kit packaging before starting. Jackson equipment and tempering kits can vary by model, and a kit intended for one machine may not fit another. Confirm the part number and check the manufacturer’s current installation instructions. Do not rely on appearance alone.
- Check local requirements. Confirm with the plumbing inspector, facilities manager, or a licensed plumber whether a drain tempering device is required and how it must be connected. Requirements for commercial dishwashers, floor sinks, indirect waste connections, air gaps, and maximum discharge temperatures vary by location. The kit does not replace any required air gap, backflow protection, or approved waste receptor.
- Shut down and isolate the equipment. Turn the dishwasher or other appliance off and let it cool. If installation requires access to electrical components or a water supply, disconnect power at the appropriate breaker and close the water supply first. Follow the equipment manual’s lockout procedure in a commercial setting. Never work on a hot drain line or open a pressurized water connection.
- Locate the specified drain connection. Use the diagram supplied with the kit to identify its inlet, outlet, and any cold-water connection. Confirm the intended flow direction; reversing the connections can prevent proper mixing. Keep the unit accessible for inspection and maintenance, and position it as directed rather than improvising a mounting location.
- Fit the drain connections. Remove or disconnect the existing drain section only as directed by the equipment instructions. Attach the machine drain and waste outlet to the kit’s marked connections, using the specified fittings and clamps. Make sure the drain hose is not kinked, stretched, crushed, or routed in a way that conflicts with the equipment’s required drain height or air gap. Do not use sealants or adapters unless the manufacturer approves them.
- Connect the cold-water supply, if the model requires one. Use only the connection method and supply conditions specified in the kit instructions. Keep the supply shut off while making the connection, secure the fitting without overtightening, then open the valve slowly and check for leaks. Some tempering arrangements do not use a separate supply connection, so do not add one unless the kit diagram calls for it.
- Restore power and run a controlled cycle. Clear tools from the area, restore the water supply and power as appropriate, and operate the equipment according to its manual. Watch the drain connection throughout the discharge. Stop the equipment immediately if you see a leak, hear an unusual sound, notice water backing up, or find that the drain hose is moving.
- Check the installation and discharge. Inspect every joint for leaks during and after the cycle. If a temperature check is required, measure the discharged water using the method and limit specified by the kit manufacturer or local code; avoid contact with hot discharge, which can burn. A plumber should correct a temperature or drainage problem rather than adjusting an undocumented valve or changing the plumbing layout.
- Record and maintain the setup. Note the kit model, installation date, and any required inspection results. Keep the instructions nearby. Inspect the unit and connections periodically, and follow the manufacturer’s cleaning and replacement schedule. If the appliance is moved, serviced, or connected to a different drain, have the installation reassessed.
Tips
- Match by model number, not by guesswork. If the equipment label is missing or the part number is unclear, contact Jackson’s technical support or a qualified parts supplier before buying a kit.
- Do not substitute a generic mixing valve. A visually similar valve may have different flow capacity, temperature limits, or connection requirements. Use an alternative only if the equipment manufacturer and the local authority approve it.
- Keep the drain path open. Kinks, low spots, undersized fittings, or an incorrectly positioned air gap can cause slow draining or backups even when the tempering unit itself is properly connected.
- Use a qualified plumber for uncertain work. Commercial drain connections and electrical isolation can involve code requirements and burn or shock hazards. Stop if the instructions do not clearly match the installed equipment.
Serving Suggestions
This is a plumbing component, so it is not served as food. In practical use, the kit belongs between the equipment’s drain and the approved waste connection, installed in the orientation and location shown in its instructions. Keep it accessible for inspection rather than concealing it behind a fixed panel. If a service record is useful, attach or keep a note identifying the kit model and the date it was installed.
Variations
There is no culinary variation, but tempering setups differ by appliance, kit design, and jurisdiction. One approved model may use a self-contained mixing arrangement, while another may require a specified cold-water supply. Connection sizes, mounting orientation, discharge limits, and permitted waste receptors can also differ. Treat the manufacturer’s diagram and local plumbing code as controlling; do not combine parts from different kits or adapt a kit based on a general online diagram.
Storage and Reheating
There is no food to store or reheat. Store an unused kit indoors in its original packaging, in a clean, dry place, and keep small fittings and instructions together. Protect the unit from freezing, moisture, impact, and chemical exposure. Once installed, it does not need food-style refrigeration, but it should be inspected for leaks, corrosion, damage, or blockage at the intervals specified by the manufacturer. Replace damaged parts with approved components rather than patching them.
Frequently Asked Questions
What does a Jackson drain water tempering kit do?
It is designed to mix hot drain water with cooler water before the discharge reaches the waste connection, where required by the appliance instructions or local code. Its specific function and operating limits depend on the kit model.
Is a tempering kit required on every Jackson dishwasher?
No single answer applies to every installation. Requirements depend on the dishwasher model, the type of drain connection, and local plumbing rules. Check the manual and ask the local plumbing authority or a licensed plumber.
Can I install the kit myself?
Only if the manufacturer’s instructions permit it and you are qualified to make the required plumbing connections safely. Commercial installations may require a licensed plumber or inspection. Disconnect power and isolate water when the work calls for it, and never handle a hot or pressurized line.
How do I know which kit to order?
Use the equipment’s full model and serial information and compare it with the kit’s compatibility list or official parts documentation. If the listing is ambiguous, confirm the correct part with Jackson or an authorized supplier before ordering.
What should I do if water leaks or backs up after installation?
Stop the machine, shut off the water supply if the kit uses one, and disconnect power if it is safe to do so. Do not continue operating it. Have the fittings, hose routing, drain capacity, and required air gap checked by a qualified service technician or plumber.
Does the kit eliminate the need for an air gap?
No. A tempering device and an air gap serve different purposes. Keep any air gap, indirect waste connection, or backflow protection required by the equipment manufacturer and local code.
