Who is responsible for the water pressure coming in to a house?

the water company - if you look on their website it should tell you what the minimum water pressure you should expect is. You can test this by timing how long it takes to fill a certain size bucket. This is only cold water. The hot water pressure will depend on your boiler and should not be reported to the water company. There is more to this Yes the water company states what the min pressure should be in some cases as low as 8 PSI but before you start doing the bucket measurement one has to know the size of their pipe as each diameter will give a different flow rate and also what material your water main is as many ferrous mains do have a severe build up of mineral deposits which also affects flow rates . Also some mains do get "crushed" over the years if proper compacting is not used to insure the main is not bearing to much weight

What has more fat - cold water or warm water fish?

Cold water fish will store more fatty tissue by size than warm water fish do. They pack on the added fat for lots of reasons like spawning, travelling or for protection from cold water temperatures. Warm water fish tend to move around a lot more and will also probably eat less by their size although warm water fish do get much larger overall.


Why does cold water effect the muscles?

Should the cold-water inlet and hot-water outlet be the same size on a 50-gallon electric water heater?

The inlet and outlets are the same size on a tank, weather your plumbing is the same size should be the question. This is not critical, but they should be the same,if there is no backflow restrictor on a plubic line and the inlet is larger then the outlet,then you could be pushing hot water into the pubic line. New installs recommend an expansion tank,but few people install them,unless they get water hammer,knocking sounds. But most new water heaters have a restrictor built into the inlet. There is no difference between gas and electric, the water does not know how it is being heated.
