You replaced the cold water nipple on your hot water heater now you have NO water pressure at all?
No pressure anywhere or only hot water faucet? I'm guessing just at the faucets. Very often when you open up the water line rust and sediment will break off and plug the screens on the faucet. Sometimes it lodges in the faucet itself. Most faucets have a screen at the end of the spout that unscrews. I'll bet that solves your problem.
If you have replaced the water pump thermostat and heater core and ran water through the radiator but it is still overheating Should you have the radiator pressure tested?
What would cause low pressure in a shower when you have replaced the hot water line out of the water heater?
Generally this is caused by pressure being built up from the water getting hot in the hot water heater. By code you should have a hot water heater expansion tank on the cold water inlet of the water heater to absorb the added pressure. If this is your problem, the excessive pressure could possibly burst your water heater. The faucet stem or cartridge or washer may be loose or moving and blocking flow.
It serves to release abnormally high pressures before they damage a system. For example, a water heater contains a pressure relief valve. If a thermostat malfunctions, the heater would continue to heat, turning water to steam. The higher pressure created by that would cause the water heater to explode- but the pressure relief valve reacts to the higher pressure, and vents it off safely.
Will adding another water heater boost the water pressure in the house in addition to giving more hot water?
No and yes. No, you won't get more water pressure. To do that you'll need to find out why the water pressure is low. Perhaps flow restriction, perhaps a poorly adjusted water pressure regulator, perhaps low pressure from the well/city water. But an additional water heater will certainly give you more hot water. It would be like putting in a LARGER water heater. In most cities the water pressure required is about 20 PSI. Small…
from experience the big one on intake (thermostat housing) goes to top of radiator. big one on water pump (pump out put) goes to bottom of radiator the nipple on intake goes to heater core top or bottom docent matter top preferably and their should be a nipple on water pump that goes to other nipple on heater core don't know why u need a diagram very simple
The heated coolant from the engine comes out of the fitting nearest the thermostat, then enters the lower heater hose nipple (or the smaller of the two nipples) then the coolant comes out of the heater and returns into the fitting on the water pump. All fittings and hoses attached to the water pump are return lines.
Older style tubs have a pressure switch usually mounted directly on the heater manifold, or attached to the plumbing. The pressure switch is connected to the spa pack/circuit board with 2 wires and shuts the heater off if there is not enough pressure in the heater tube/manifold to protect the heater from becoming damaged or even exploding or causing a fire in a dry heater condition. Newer spas that use Balboa controls have sensors built…
Hot water is lighter then cold water so it would stay up on top of cold water till both waters naturalize to the same temp. a good example is a water heater and (if its not to old) open your drain at the bottom of the water heater and if your dip tube is still good you should always get cold water out of it even if the water heater is on and your water…
