Toy poodles can run about 5-10 mph.Medium poodles can run about 15-20 mph.Large poodles can run up to about 20-35 mph.Minor edit?ow my female border collie who is the same age and a little smaller can out run her no problem. I have yet to clock her but i am confident it will be around 30 or 35 mph. my poodle is also not nearly as agile as my border collie, though.
Valve Closure and Opening. One of the primary causes of water hammer is the abrupt closure of a valve. At the end of the branch is a valve. The black arrows show the flow direction in the primary and branch lines, and the blue arrow is the length of the branch line.
You can buy xxxx on hammer arrestors to help with this problem once you figure out which supply line is the culprit. The other big problem is loose pipes. As the water flows through them the temperature change causes them to expand and contract. The force of the water is sometimes enough to make them vibrate as well. To fix this you'll have to open the wall where the rattle is and secure the pipes. You don't want them rattling around, possibly weakening the joints over time. I hope between my thoughts and those on the other answer you can narrow it down. If you still have trouble call a plumber out.
