Quick Answer. The pressure switch to a well pump may shut down a well or cause the water not to flow, especially if both the switch and a pressure tank are affixed to the system. Both parts can cause an over-circulation of water, which, in turn, shuts down a system.
Rating Newest Oldest. How much a skateboard costs just depends on what you get and where you buy it. Skateboards are cheaper than they were a decade ago. Here's a page of some good skateboards: http://www.amazon.com/gp/search?&index=s... As you can see, there are plenty complete ones for around $40, a few even cheaper. There are also ones that are over $100.
I'll assume that ultimately you're figuring your child will continue into figure skating and isn't just going to learn to skate and then call it a day. If that's the case, you don't need particularly expensive skates if it's a young child learning to skate. You can find reasonable skates starting from $50 to $60. An older child or an adult, you're probably going to be spending a bit more. If they're just learning to skate, they don't need a figure blade with picks on the toe. A hockey type blade is fine for learning the basics.
