Of the solutions available, can hotun be the cheapest?
The fitter has several options, besides hotun, that would satisfy the regulations.
All have their pro’s and con’s
- He can run the pipework to an outside wall and discharge in a conspicuous and safe place over a suitable gully or soak away. – This is suitable if the installation is on an outside wall and there is a means of discharging in a safe and conspicuous manner. The installer is faced with having to drill through the fabric of the building, sleeve and seal the tube. (Number 3 above)
- He can run to an internal tundish (with air break to drain) which will be located in a conspicuous but safe location and then out through the outside wall to discharge in a safe place (Number 5 above) – Same issues as point no.1.
- He can run to an internal tundish (with air break to drain) and then to a device that can act as a (mechanical) odour trap (Numbers 2 & 3 above) and thereafter to connect to a local foul waste or soil pipe – This has become an accepted and viable method but it does require two products with all the associated fittings required to connect them and especially in an under-counter installation where space and height are critical, it can be problematical.
- However you can now take advantage of RA Tech’s unique and innovative product, hotun. In ONE product you get a tundish with an inbuilt effective mechanical odour seal, it’s the most cost effective solution anyway!
