The HotKit 500kPa Hot Water Installation Kit is a complete, ready-to-fit valve assembly built for speed and compliance on storage hot water jobs, adding a 500kPa pressure limiting valve to the standard HotKit line-up for full inlet pressure control.
Built for both horizontal and vertical installations, the kit includes fully WaterMark approved, lead-free brass components and an insulated PU cover that meets AS3500.4, so every job stays efficient and compliant.
Features
- 500kPa pressure limiting valve (lead-free) for consistent downstream pressure and system protection
- Dual isolation non-return ball valve with check valve for serviceable, safe isolation
- Tempering valve pre-fitted and certified to AS4032.2 for temperature control compliance
- Insulated PU covers supplied, compliant with AS3500.4
- Suits horizontal or vertical installation
- Lead-free and WaterMark certified, tested to AS4032.2, AS1357, AS3688 and WMTS 012

Applications
Suited to storage hot water systems in domestic and commercial settings where downstream pressure limiting, back-flow prevention, insulation and fast, tidy installation are all required in one assembly.
Installation Notes
- Ensure the mounting area is clean, dry and accessible before installation.
- Retain the insulation covers until final plumbing connections are complete.
- Set the tempering valve to local code requirements and confirm the pressure limiting and check/isolation assemblies are installed in the correct orientation.
- After installation, pressurise the system and check for leaks before cladding the insulation.
- Observe current regulatory requirements for hot water system installations, including safe access for maintenance and servicing.
Save installation time and deliver a clean, professional finish on every hot water job – the HotKit 500kPa Installation Kit combines all the critical components into one convenient, pre-tested set.
