Q:Basin double hole faucet outlet pipe bottom leakage how to do?: The basin under the seal ring aging, sealing lax. Can be replaced all the water, because the old water is dirt, the price is not expensive, the replacement of new health, save trouble.

Q:Understand the water to the high reward: The center of the basin to the sides of the wall to leave a 550mm clearance size. The size of the toilet has a minimum of some control, the minimum width of 550mm, 600mm side of the toilet in order to save space to the toilet to narrow to 100mm or so, but even so, the wash basin is not only 300mm wide, must be highlighted Wash the table, it is not convenient to put things. Another key is to wash the center of the basin to the wall on both sides to leave a 550mm clearance size, that is to have 1100 of the net to put your desk, otherwise the use of bad and bad, so some Do not wash the table, it is necessary to a floor of the wash basin, put a soap what. But the more commonly used for a size of the basin: table 850mm, table basin: table 750mm, the size of the bathroom toilet is installed the standard size, but according to their actual situation, if the average height of the family are more High, then of course, is to design a little higher, if the average height of the home is not very high, then it is recommended to install the bathroom toilet lower.

Q:Basin faucet with shower how to connect the water pipe: At a distance of about "H" from the faucet outlet, drill three holes with a diameter of 6 mm and a depth of 35 mm.

Q:Im trying to replace my faucet sink in my bathroom the bolts wont come off ! I tried using the wrench I have but it wont turn what can I do? is there another tool I can use: Yes, it is called a torch. A pencil torch, a regular berzamatic torch. Either will work. They cause the metal to contract and expand loosening the bolts.

Q:Kitchen faucet always close tight, leaking, what is the reason?: You put the faucet down, there is a rubber pad, and then to repair the bike there is still a cut off on the OK

Q:of diameter 60cm with water at a rate of 2 L/min. Find the rate at which the water is rising in the basin when it is HALF full. [Use the following facts: 1 L is 1000 cm3. V = pi (rh^2 -1/3 h^3]I need help with this asap. Thank you!!: Equation of the hemispherical surface x? + y? + z? = R?, (-R z 0) The volume of water in the basin with the height h: . . . (-R+h) V = ∫ π(x? + y?) dz . . . -R . . . (h-R) V = π ∫ (R? + z?) dz . . . -R V = πR?[(h - R) - (-R)] + (π/3)[(h - R)? - (-R)?] V = πR?h + (π/3)(h? - 3h?R + 3hR? - R? + R?) V = πR?h + (π/3)(h? - 3h?R + 3hR?) dV/dh = πR? + (π/3)(3h? - 6hR + 3R?) dV/dh = πR? + π(h? - 2Rh + R?) dV/dh = π(h? - 2Rh + 2R?) dV/dh = (dV/dt)/(dh/dt) dh/dt = (dV/dt)/(dV/dh) dh/dt = (dV/dt)/π(h? - 2Rh + 2R?) There is an ambiguity when you say HALF full. It can be interpreted as the water was filled up to half its maximum height (R) or filled up to half the volume of the basin (2πR?/3) I will take the case in which the water was filled up to half its maximum height: h = R/2 dh/dt = (dV/dt)/π(R?/4 - 2R*R/2 + 2R?) dh/dt = (dV/dt)/π(R?/4 - R? + 2R?) dh/dt = 4(dV/dt)/5πR? Plugging in dV/dt = 2000 cm?/min R = 30 cm dh/dt = 4*2000/4500π dh/dt = 16/9π cm/min. dh/dt ≈ 0.57 cm/min.

Q:I am trying to replace my kitchen faucet. I have done this before, but never at this house. I can not for the life of me get the old faucet out of there. The nuts are too old and rusted, I have tried a high quality penetrating oil, that didn't seem to work. I am also not too comfortable using a torch, so that's out of the question. There was advice on another website that said just to use a good drill and drill through the nuts since I'm replacing them anyway. I'm not sure if this is really a good idea, but I am at my wits end!The other problem I'm having is I can't figure out how to get the old mounting parts off either. I can take pics with my phone if anyone needs to see them.Any help would be appreciated!!: First of all, you need the right tools for the job. You will need a "basin wrench" which is a long wrench (12-18") that has a head that flips for either tightening or loosening the nuts. This wrench will keep your hands below the bottom of the sink and help prevent "bloody knuckles syndrome". If the nuts are frozen to the point that a basin wrench won't turn them, use a "mini hacksaw" to cut one side of each of the nuts that hold your faucet to the sink. If the nuts are made from brass, this will be relatively easy being that brass is a soft metal. Once you cut the nuts, use a flat screwdriver to open the gaps created by hacksawing through the nuts. At this point, the nuts should be removed easily. When you are lying under the sink and looking up at the faucet base, BE SURE TO WEAR SAFETY GLASSES! When you put on your new faucet, be sure to lightly coat all threads with a good quality plumber's grease. This will make repairs/removal alot easier next time.

Q:What can be used to remove the scale on porcelain: This is very easy to do ah, the oldest way is that we can face the surface of the surface screwdriver can make a clean

Q:Basin basin faucet water hose position is too deep, how to screw down?: If you change the tube, then the tube can be cut with the pliers to take it off, with a pliers to clamp the tube will be able to dry down.

Q:Is the installation hole of the faucet used in the home kitchen the same? Are all 3CM? Will not buy a result not installed?: Not the same, installed in the sink on a single hole hot and cold faucet that is 3CM there is a single cold faucet, that caliber is 4 points
