The solar pumps I have been using for the last few years are beginning to fail so need to look at replacements. At the moment I use cheap Chinese tattoo machine adjustable power supplies to vary the flow rate of the pumps.
I was hoping to make some big parastaltic pumps before I had to buy more but I have too much on at the moment so new pumps it is.
Looking at the TopsFlo TL-B10 Pump I can just use a ball valve and a static PSU, marvelous
Before I go and buy a couple with 1/2 BSP so I can put quick release connectors on, as I haven't really been paying attention to new shiney kit for a while, is there anything else I need to consider before buying them?
