For a given volume of water per second, the two 32mm pipes will have a lower pressure loss than the single 40mm pipe. Using the head loss calculator at http://www.engineeringtoolbox.com/hazen-williams-water-d_797.html, and assuming you're using PVC pipe, I found the following pressure losses. Each line gives the flow rate, the loss for a single 40mm pipe, ...

Turn off water supply to water heater, turn off (not pilot) gas to water heater. If the cold water shutoff to the heater is beyond the break, turn off the main water supply valve.

It's a matter of degree. As the pressure tank discharges, the water pressure will go down. When the pressure goes below a certain threshold, a pressure switch will turn on the pump, and the tank will start filling and raising the pressure. When the pressure goes above a different threshold, the switch will turn off the pump and the pressure should be ...

You are experiencing a fairly normal event for a well with pump and pressure tank, though if the behavior seems new & different the pressure tank may require maintenance or repair/replacement. Most well pumps (there are exceptions, such as "constant pressure pumps") run on a simple differential pressure switch with a 20 PSI differential (often ...

I suspect you're seeing the result of poorly-translated product descriptions from China and elsewhere. For example: Advantages: Withdrawing life greatly improved. Should not damage the leaking. The inner tube using the nylon braided package EPDM more resistant wound. Honory99 1.5m Pull-type Copper Core Explosion-proof Shower Hose This product would ...

This is a common complaint for these types of water heaters. Unfortunately, you have a model that seems to be slow to respond to water flow. I don't think any company has a way to adjust the flow sensor on their on-demand water heaters. This is not a customer adjustable function of these style of heaters. If you're dissatisfied with this product I would ...

You need at least the same flow rate out of the hose that the pressure washer uses. look at the GPM (Gallons per minute). With the hose on the roof, run the hose wide open for a minute or 2 so you will have the true flow rate. Then fill a bucket and time how long it takes divide by the size of the bucket if your unit uses 2.5 gallons per minute, a 1 gallon ...

To achieve the maximum flow keep your pump at ground level. With a 1/2" slightly pressurized intake it may help to put 3/4" out put to the water tank but much larger would probably be a waste of $. Make sure to have water in the pump at all times the shaft seals are usually ceramic with no water they overheat and crack. This would be another reason to keep ...
