Perfect RW, it's appreciated!

I have the maual, I was just looking for some worksheets to refresh my math skills.

I am taking a Cal. DHS distribution exam in about a month and would like to brush up my math skills, does anyone know of a site to download practice questions in the form of a worksheet?

You need a mechanical joint transition fitting. Measure the outside diameter of both pipes, then click the link below to find what you need. The fitting should not be installed IN the thrust block, and there are insulations that can be applied wet, that will dry around the fitting...

Hello all, I would like some feedback on the in-place pipe restoration from someone who has maintained a plumbing system after this has been done. I work at a California University, and maintain a 50 year old, 6-story library that is in dire need of a re-pipe, and management seems to be sold on...

These formula's may help, you need 2 knowns to get the 3rd. Quantity= Area x(multiply) Volume Volume= Quantity % Area Area= Volume % Quantity Also, 1ft. of water(head) is equal to .433 pounds. You can then use another equation to get cubic feet. Pounds of water x 0.0166032= cubic...
