The Merlin comes with no inlet fittings. This adaptor allows you to connect your merlin directly to a standard 3/4" BSPM branch fitting (washing machine/dish washer fitting) for easy installation. Alternatively a hozelock fitting can be screwed directly into this adaptor so that the merlin can be dirrectly hooked up to a hoze pipe. This fitting will also fit an outside tap.People who bought this item also bought:
