Is a bladder tank better than a galvanized tank?

Depends on what you consider better? If a bladder fails you need to rush out and get a new one if a galvanized tank gets floooded you can drain it and your back in business


What could be the cause of water leaking from a new furnace?

Water leaking from a furnace most likely occurs from the heat of the furnace which transforms into a liquid. The best way to avoid the leak is to put your furnace at a lower temperature.


Why does a new roof leak but not near a chimney or vent stack?

What's above it on the roof ? Water may be running down a joist for a bit. A new roof, properly felted and roofed shouldn't have any place for it to leak. Type of roof could make a difference, I'm assuming asphalt shingles. If possible, look in the attic to see if you can see a water stain around the leaking area.


What is average price plumber to install a new shower faucet?

4 hours @ $175 per hr not including travel time or parts tile replacement performed by others Above is only correct if you need it DONE NOW!! But realistically I would charge about $300.00 if its a simple switch not including the valve. It would take about 1.5 hrs and if its galvanized pipe in a tight area then it might run $500.00 - $800.00 depending on the situation not including the valve.


How do you use union in embedded system C programming?

All members of a union are assigned the same memory address. As such, assigning to any member of a union changes the value of all members in that union. The total number of bytes allocated to a union is equal to the length of the largest member of that union. Where the members differ in length, assigning to a member will completely overwrite all the smaller members but will only partially overwrite any larger members. After assigning a value to a union member, that member is said to be "active". The active member remains active until a value is assigned to another member. However, a union does not keep track of which member is currently active; the onus is entirely upon the programmer to ensure the correct member is accessed. In some cases, keeping track of the active member is not necessary. For instance, consider the following union: union u { int i; char c[sizeof(int)]; }; This union has two members, both of which are the same length, sizeof(int). We can read and write integer values through the u::i member just as we can any ordinary integer, however the u::c member allows us to read and write the individual bytes within the integer. Since both members are integral types, there is no need to keep track of which member is currently active; it simply provides two methods of accessing the same memory. Thus if we need to access a multi-byte value at the byte level, a union provides the most intuitive method of achieving it without resorting to type casting a pointer. Where members differ in size, we often need to keep track of which member is active. One method of achieving this is by embedding the union in a struct along with an enum member to keep track of the active member of the union: typedef enum a_t {num, arr} a; union u { int number; int* array; }; struct s { u data; a active; }; In the above example, we can choose to store a single value in s::u::number or we can choose to store multiple values in the memory pointed to by s::u::array. However, if we store a value in s::u::number and then attempted to dereference the s::u::array pointer, we incur undefined behaviour because a) an int and a pointer (to any type) are not guaranteed to be the same length and b) the number may not contain a valid address. Therefore it is important that whenever we write to s::u we update s::a to reflect which member was written to and we must read s::a before accessing s::u. In addition, we must be sure to release any resources currently allocated to the s::u::array before assigning a new value to s::u. In this example we don't actually gain any benefit by using a union because we end up using just a much memory as we would if the two members were allocated to separate addresses, because of the need to keep track of the active member. However, if the union has three or more members, we begin to save memory because all the "inactive" members cost nothing.

Just installed a new shower with new copper pipes going from galvanized pipe now there is very little water pressure why?

Anytime you disturb galvanized pipe you usually have some rust or buildup come loose. This will either stick in the valve or clog the shower head. Depending on how old the galvanized pipe is and how hard your water is you may have to clean the control valve several times.
