Q:The same hot water pipe, bathroom basin basin faucet hot water, shower was warm water.
This problem is really the first time encountered. Usually the pipeline is too long, you need to take a long time to solve the water, because the cold water in the pipeline to go out of the reasons. As for your question, since you have found a hot water and warm water at intervals, then you let the plumber turn the basin faucet and the shower into the water pipe down is not the problem solved. If resolved, then it is your hot water separator problem, because you divided the six exports, may be a water separator or you use 3-channel change, then it is a problem. hope this helps!
Q:There is no way to directly from the basin leading to the water tank inside the bucket
From the outlet to install a three-way, the other tube to install the valve, I think you want to use water
Q:Kitchen faucet is single or double control
Double control is better
Q:Taiwan Basin, Taiwan basin counters and Taiwan Basin faucet separately to buy trouble?
Look at the amount of lead when the size of it, the location of the high and low outlet
Q:In the cost-effective to buy a faucet, but the caliber and the basin set the caliber is not as large as the size of the next three are 3cm, almost?
Home is generally the diameter of the water pipe is 15, if the interface is not the same big, you can go to the plumbing shop to buy a conversion head, very cheap.
Q:Kitchen wash basin faucet handle how to repair the water leakage
There is a problem, and repair up a lot of trouble, change a new bar
Q:Is it necessary to use a corner valve below the basin faucet? What is the role?
Home use, do not install the angle valve, the faucet is broken, the direct closure of the water inlet valve is also possible, but may be more or less have a certain impact.
Q:Only change the water, why the goldfish will still surfaced mouth soak?
Water or hot weather, hot air pressure, and floating head breathing exogenous floating head is water hypoxia. Under normal circumstances, dissolved oxygen in the water below 1 mg per liter of fish will float, less than 0.5 mg per liter will suffocate death, high oxygen fish to 0.5 mg will die. Water hypoxia, to add air pump or filter. May be hungry or too high to get sick.
Q:A faucet is filling a hemispherical basin?
Equation of the hemispherical surface x² + y² + z² = R², (-R z 0) The volume of water in the basin with the height h: . . . (-R+h) V = ∫ π(x² + y²) dz . . . -R . . . (h-R) V = π ∫ (R² + z²) dz . . . -R V = πR²[(h - R) - (-R)] + (π/3)[(h - R)³ - (-R)³] V = πR²h + (π/3)(h³ - 3h²R + 3hR² - R³ + R³) V = πR²h + (π/3)(h³ - 3h²R + 3hR²) dV/dh = πR² + (π/3)(3h² - 6hR + 3R²) dV/dh = πR² + π(h² - 2Rh + R²) dV/dh = π(h² - 2Rh + 2R²) dV/dh = (dV/dt)/(dh/dt) dh/dt = (dV/dt)/(dV/dh) dh/dt = (dV/dt)/π(h² - 2Rh + 2R²) 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 (2πR³/3) 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(R²/4 - 2R*R/2 + 2R²) dh/dt = (dV/dt)/π(R²/4 - R² + 2R²) dh/dt = 4(dV/dt)/5πR² Plugging in dV/dt = 2000 cm³/min R = 30 cm dh/dt = 4*2000/4500π dh/dt = 16/9π cm/min. dh/dt ≈ 0.57 cm/min.
Q:Why does our sink have 6 holes for faucets?
you can always buy a chrome plug ..... faucett ....sprayer.... soap dispencer...... instant hot or filtered water
