The JOHNTECH CPM and CPW Series – Peripheral Pumps are non-self-priming units and the suction point of the pumps must always be installed below the water level of the tank. The pump must be installed on a flat surface that would not flood in heavy rain. The JOHNTECH CPM and CPW Series – Peripheral Pumps are especially designed for domestic use on rainwater harvest tanks, small to medium garden irrigation systems, long distance water transfers, heating ventilation and air-conditioning systems, pressure boosting water pipe systems and urban water supply systems.

16mm2 5 AWG DC Battery Cable Black - Sold Per Meter
This battery is a true AGM type not the cheaper hybride AGM (Enhanced Flooded Battery). It is the recommended large battery recommended by Centurion for gate motors. They need to be AGM so they can handle the high start current of the gate motor.
Best price by far. A third of most other dealers. Fast delivery.
Have been using with water from a borehole with very high lime content. Now have no lime scale buildup in the kettle or the shower heads. Works well very happy
The Uni-T UT202A clamp meter is a top class electrical tester.The meter is easy to use, accurate and an excellent addition to any electrician's tool kit. I absolutely recommend buying it and I am very pleased that I bought it from Livesustainable. Their service is excellent.
Take a breath. I raised my irrigation pump about a meter off the ground. Constantly loosing prime, I check, rechecked and replaced the non-return valve on the inlet side. Online research pointed to the outlet siphoning out the prime due to the height. This vacuum breaker on the outlet side solved the problem 100% by allowing some air into the system, without draining the prime, as the water in the pipe dropped down to ground level, whenever the pump is switched off. No more priming issues.
Perfect for my project
Finally the right rectifier spec for my current project. It works great...
Extremely effective. No need for anything else, quiet and uses almost no power. The noise when dealing with larger bugs need some getting use to
