The hotun detect alarm unit from RA Tech, has been specifically designed alongside our innovative hotun dry trap tundish range to help with the easy identification of water dripping or flowing from a systems relief valve, via the tundish, which indicates there is something wrong with the system. This in turn helps the consumer identify an issue to carry out vital remedial repairs, preventing unnecessary breakdown of the system and also saving water and energy.
hotun detect is the world’s first, in-tundish, water detection and temperature sensing audible and visual alarm system. When the relief valve passes water, hotun detect senses the water and, depending on the temperature of that water, will automatically indicate, that there is something wrong with the system.
There are four levels of warning, they are;
Stage 1 – 0 – 20°C
Stage 2 – 21 to 60°C
Stage 3 – 61 to 85°C
Stage 4 – 86°C + (critical alarm)
When the relief valve drips, the hotun detect unit will emit an audible (70-74dBA) and visual alarm. The type of alarm will indicate which temperature stage alarm has been activated (for full alarm functions please read the Operation and Installation leaflet document below). This information will help the engineer with fault diagnosis.
hotun detect’s simple, quick hook on design means it is fitted in seconds and as it is battery operated (2032 coin cell), it requires no specialist electrical knowledge to fit.

Access Chambers are installed close to a house, usually on a path or patio near to the top of the drain so they ONLY have the option of a light-duty lid for pedestrian areas such as patios and paths (A15 Rating).
Only a 450mm Inspection Chamber should be used on a driveway or high foot traffic area, and the appropriately rated lid must be used to comply with The Building Regulations.
Inspection Chambers are a very important part of an underground drainage system, they provide access for testing and inspecting, as well as clearing blockages.
There are different types of inspection chambers, each with its own intended use and placement, depending on circumstances such as location, depth and foot or vehicle traffic. We’ve created a quick guide below:
Access Chambers, often referred to as mini or shallow access are used close to a house, and near to the top of the drain, so they’re not fitted deeper than 600mm (0.6m) and have a diameter of 300mm. They provide easy access for inspection and equipment.
*Access Chambers ONLY have the option of a light-duty lid for pedestrian areas such as patios and paths (A15 Rating).
Inspection Chambers are a larger version of an access chamber, usually with a diameter of 450mm to 600mm, enabling them to be installed further away from a house, and to a maximum depth of 1200mm (1.2m). They tend to also have more branches feeding into them.
Inspection Chambers a more versatile so have a choice of compatible lids rated for different applications, for example, driveways etc.
Manholes are larger than access and inspection chambers as they’re designed to be big enough for maintenance staff and equipment to enter the drainage system, they’re usually deeper than 1 metre and wider than 600mm x 900mm and lead to the sewer. They’re kept sealed and not accessible to the public.
Mini Access Chambers can be used effectively to a maximum depth of 600mm (0.6m), this is simply due to their narrow width. However, as they’re supposed to be installed near the house, they’re close to the top of the drain.
Due to them being wide enough for a child to fall down, Standard Inspection Chambers have a maximum permitted depth of 1200mm (1.2m).
*Using an inspection chamber deeper than 1200mm: In the rare instance that a deeper inspection chamber is required, then a 350mm Chamber Reduction Ring must be used, under these circumstances the maximum depth would be 3000mm (3m).
Delivery is usually within 5 working days, and you’ll receive more accurate estimates and updates via email, once we’ve processed your order.
 | Small Items: £12.50 + VAT Orders containing only small items |
 | Long Items: £22.00 + VAT Orders containing long items (pipe, guttering etc) |
| STORM Products: £50.00 + VAT Orders containing hygienic cladding and bathroom panels |
We charge a single delivery fee that is calculated and displayed in the basket, this is based on what you’re looking to purchase. For example, an order containing anything with a length to it, such as drainage pipe and guttering will cost more to deliver than an order that only contains small fittings. This is because most couriers only accept small parcels and the few that do take long items charge a premium for this service.
Delivery costs are based on product availability and delivery within the UK Mainland. Delivery to the Scottish Highlands and Islands may incur additional costs, if applicable, these will be given in the checkout after a delivery postcode is entered.
