No water pressure in the morning

[scornish]

Since turning on the heat a couple of weeks ago, (we have a hot water forced air system), we have no water pressure each of the mornings. I prime the pump to 40psi and all is well until the next morning. Furthermore, the water is somewhat cloudy.

The water tank is 2 years old and the water heater is 1 year old. The system worked fine last winter.

Before I contact my local repair guy, I thought I'd try this forum.....

Thanks in advance for any help/suggestions....

If I have this right. The hot water heat dont have anything to do with the well there. Now if you have to prime the well pump each morning. Id say that a check valve or foot valve is not working right. you dont say just what you have there for the well. Does the boiler Psi stay the same all the time?

Ed, thanks for your reply......


I checked the pressure at the top of the tank. It read 14psi, the cut off is 40 psi. So....I pressurized the tank to 38 psi thinking that I may have the solution. Nope. I lose pressure every time I run the water purifier at night. The effect of increasing the pressure to 38psi means that it takes only a minute to get it back to 40psi, rather than almost 10 mins as before, but it hasn't solved the main problem.

Does this narrow things down?

Thanks again.

You say the cutoff is 40. Does this mean you've set it at that, or is 40 psi the most your pump can manage?. If your impeller in the pump is worn or warped, it wont suck very well, especially if the foot valve is near the limit (25 ft. for a single tube pump) . i would do the following, 1.- pull the well tube and check or replace the foot valve. 2. let the water out of the pressure tank till it is almost empty, now put 20 Psi in the top and reset your pressure switch to 22 on,-40 off. More facts needed to give a good answer.

Just out of curiosity, does your pressure switch have a lever on the side of it?
If so, the switch may have a low pressure drop out on it. This is a safety feature that will shut the pump off should the pressure drop too rapidly. Sometimes this "drop out" pressure gets too close to the pump cutin pressure (especially if there is a large water demand), and the switch will drop out. I don't know the operation of the water purifier, but the demand may be such that the dropout happens.
If this is the case, check the pump operation to see what the cutin pressure is. Then drain the tank completely and set the precharge to 2 psi less than cutin pressure. Add or remove air as necessary. This should cure this proble.
If the pump is slow to build pressure, then there could be a problem with the pump itself, such as excessive wear, or a plugged nozzle (if it's a jet pump).
Let us know.
