I got my own dojo and saw some cool jitsu mats at game Sensei's dojo. I was just wondering if I could purchase those mats for my dojo because they looked really nice.
You can do this.if you dont have any problem crawling around under your home, hehehe (Ive done it for years, but still find it amusing to meet people afraid to go under a home) I would recommend cpvc pipe and fittings, and go ahead and glue them. Use brass frost free valves for outside taps. There is a pipe cutter for cpvc it looks like a large pair of pliers usually runs about $15 well worth it for the cpvc pipes. Run all your pipe and fittings before removing the old stuff, if possible. I like to pressure test a system Ive worked on before running water thru it I made an adapter that screws onto the main, that allows me to connect my air compressor to it. I pressure test my systems at 80 lbs. Just connect the compressor, turn it on and go around listening for the hiss of escaping air no water spraying everywhere to clean up that way.. heheh and most public supply, and well systems only run between 30 and 60 psi so if it holds at 80 I know it will hold for good. It would also be a good idea (if you live where it freezes during winter) to add a heat tape to any exposed pipe, such as the main supply, where it drops from the insulation to your hook up. By the way I see someone mentioned using crimping tools and rings. you don't need these with cpvc and I would say stay away from the Pex tubing, which does use them it costs more to maintain a pex system in the long run, than cpvc Good Luck
In order to produce a 10% by mass of tetrabutyl titanate in 1,4 butanediol you do not require the data you have provided. Assuming that the two are miscible and do not inter-react , proceed: Weigh out 10.0g tetrabutyl titanate. Dissolve in some 1,4 butanediol. When mixed , add further 1,4 butanediol until the total mass of the solution is 100g . You now have a 10% by mass solution of tetrabutyl titanate in 1,4 butanediol. Observe all chemical laboratory safety precautions concerning safety clothing , ventilation etc.
