Review on BOKYWOX RS15-6SG - 3/4'' 3-Speed Domestic Circulation Pump for Hot Water Circulation - Food Grade & Efficient by Jon Dugan

The pump works properly. And I received it the same day I ordered it, it was amazing. The only problem was that this pump doesn't come with nipples to connect. The threads are not tubes so I had to order brass ferrules the next day and they arrived 2 days later. So there was no point in taking the pump so quickly. If I replaced the pump and I had the fittings already in the pipeline that would be great. So be careful, this pump will not go to waste. Look around you can find the same pump with ends I think for the same price. You should make a note or be able to finish on purchase. The ends of the actual pump are not pipe threads. They are similar to a garden hose fitting and require a flat, soft washer to connect them. You may be able to grease the threads enough to make them work without the right fittings, but that will be very difficult.
