How do I get rid of Hard Water
The most economical way is to soften your water is with an ion exchange water softener. This unit uses a special resin with sodium ions to remove hardness minerals. As the hard water passes through and around the resin, the hardness minerals (ions) attach themselves to the bead, dislodging the sodium ions. This process is called "ion exchange". When the resin has no sodium ions left it is exhausted, and can soften no more water. The resin is then recharged by flushing with salt water. The sodium ions force the hardness ions off the resin beads and the excess sodium is rinsed away so that the resin is ready to start the process all over again. This cycle can be repeated many, many time before the resin loses its efficacy.
Are solar electric systems safe?
Yes. Solar cells are mostly silicon, the primary component of sand. There is no exhaust and no toxic materials to leak out of the system. The electricity coming through the inverter is just like the electricity coming from household wall sockets; you should use the same care you would with utility power. All components are approved for utility interconnection and are installed according to standard construction practices.
What type of maintenance is required on solar panels?
Solar panels benefit from a non-abrasive cleansing agent. When reviewing battery levels, check battery connections and fuse holders to ensure that they are clean and dry. If necessary, use a silicon sealant for sealing damages around the frame.
Does a generator need maintenance?
Yes. The engine oil and filters (Oil, air, & fuel) will need to be changed once in a while depending upon frequency of use. A schedule of what requires to be done is provided in the operator’s manual supplied with each generator
