Long before there were complicated electric pump systems for rural properties there was gravity.
Gravity fed hot water system problems.
Our gravity water system spring fed has worked really well for 24 years.
If power is a problem gravity may be your best bet for a reliable water supply.
When the hot and cold water is gravity fed then by crossing the water over will make getting the airlock out of the pipes virtually impossible.
If your shower is located above your cold water supply a negative head situation is created as this means water will have to travel upwards which it can t do via gravity.
As the water cools at the end of the loop where the last part of the loop is not insulated it is thermo siphoned back into the hot water heater dear tim.
Another gravity fed shower problem the shower is often the most problematic part of any gravity fed water system.
Several weeks ago i had a problem with one of the lower frost proof hydrants.
If you can physically see into the tank then you should be able to see if the make up supply is keeping the tank topped up.
To get an airlock out of either the cold or the hot water you require a water pressure more that the pipe that has the airlock in so that there is force pushing the airlock away.
Tried to turn on it was hard then dirty water.
Gravity hot water recirculating system a gravity hot water system works because the heated water which is lighter rises through the loop.
Came up to house about 1 hour later and top of my water filter original was cracked and water spewing and had flooded my basement.
The flow rate you are currently getting from your water system combined with the number and type of installations you have in your property will determine what kind of pump you require.
Hot water boost pump problems with gravity fed system by andycain tue jul 31 2018 11 05 pm last post by harrisjohnpaul thu aug 09 2018 9 18 am.
Only low pressure gravity fed water systems can be pumped.
