The  Reliance 6 6 SOMS K will also be ideal for lodges, cottages, caravans, trailers, RV’s, boats, garages or workshops, artists’ studios, small shower-sized bathrooms, and even outside barbecue areas.

Technical Specifications and Installation

The Reliance 6 6 SOMS K is a 6-gallon compact electric water heater working from 120 volts and incorporating a single stainless steel heating element of 1650 watts. The factory-fitted T&P valve (temperature and pressure relief valve) comes with 2-inch insulation.

One customer mentioned that it is important to read the installation manual before installing and also to make sure that you purge all the air from the water tank before switching it on, because the heating element could burn out in a short period of time the air is not completely purged from the empty water tank.

When installing the unit, it is important to position it in such a way that the existing water piping as well as the electrical power hookup will need the shortest distance in between the connections. Also install the water heater in such a way that you’ll be able to easily reach the drain valve as well as all of the access panels when the unit is fitted in place, because this will make it simple to service the unit.

It is also important to note that the unit must be level before you start with the piping work.

The manufacturer also strongly recommends that dielectric couplings or unions must be installed on the Reliance 6 6 SOMS K water heater when it happens to be connected to copper pipes, in order to protect the unit against the premature corrosion of cold and water fittings.

Lastly, keep in mind that it is best to obtain the services of a competent and qualified electrician if you aren’t acquainted with electric codes or practices, or if you have any kind of doubt in your own ability to connect up the electrical wiring to this water heater.

Negative Points

There were no real negative issues reported by customers online. One customer complained that the photo of the unit on the web site shows a switch on the side of the unit, but when the unit arrived, it did not have the switch installed, and as such, if you want to pre-wire the installation before your unit arrives, remember to always wire with a disconnect option in place.
