Why would I have cold water pressure but no hot water pressure?
This is because the flow of water is attempting to go from a large pipe into a smaller one. The main house water supply shutoff valve is partially closed. If the water main supply line has been partially closed, it will cause a reduction in the water pressure in both hot and cold water lines.
What does it mean when hot pressure is good but cold flow is poor?
When hot pressure is good but cold flow rate is poor we can but guess that there is a clog at a pipe elbow or valve. It’s not air lock as water pressure would force air through the lines and out at the nearest plumbing fixture. Subseqent loss of all water pressure suggests further debris clogging.
What does it mean when your hot water pressure is low?
General low water pressure: It is possible for the entire house to experience a sharp drop in lower pressure. In such cases, both the cold and hot water supplies flow reluctantly. The fix is usually from the main water supply entering your home.
Which is worse hot water or cold water?
at CLOGGED PIPES / TANKLESS COIL DE-SCALE. If mineral clogging of the building plumbing system is a problem, usually we notice that hot water pressure is worse than cold water pressure, but also that the hot water pressure declines over time, rather than appearing to suddenly diminish severely.
Why is there no pressure at my hot water faucets?
If you have good water flow (“pressure”) at hot water faucets, but it’s cold, then the water supply piping is not blocked and the problem is in the water heater itself, or in a mixing valve. If you have weak or no water flow at hot water faucets then the water heater cold water inlet or hot water outlet…

If your hot water pressure is low but the cold is fine, meaning the hot water pressure lower than cold, it could be that the hot water tanks valve is partially closed. Inspect the tank and the valve to see if it is completely open. If that is not the case, it could be a clogged line coming from the hot water tank that has had build up or corrosion.
