Fresh Water Pressure tips for the newbies...
I read with interest a thread of Martin R titled City Water Connection Problem. Not that it is a common problem, there is a sequence of operation checks before creating a situation where “something is broken in the Airstream”.
1- When you connect your hose to “city water”, flush the hose before attaching it to your trailer. When you remove the hose from your trailer, drain as much of the excess water possible. THEN attach both ends to one another. It keeps “things” from getting into the hose and also any dripping in your hose storage area.
2- Many complaints are about their water pump “not getting to pressure and keeps running”. That is probably because you did not FLUSH the air out of your system. Air compresses... water not so much in comparison. When connecting to city water, we take a pan after five minutes or more to each faucet. Open the faucet on the cold and purge the air. Then to the hot side. Then go to the next faucet doing the same. This includes your indoor shower and OUTDOOR shower faucets. Then go back and purge any air still remaining. You take the clean water each time the pan fills to some fortunate plant near your trailer. (Run the water long enough so it can fill the Hot Water Tank! That is the delay reason...)
3- IF you are using your trailer’s water pump... fill the fresh water tank or fill to a level you want, if you are traveling and carrying just enough fresh water in the event you stop somewhere. THEN with the tow vehicle attached for power/or external electricity source, purge the faucets as in #2.
4- Your pump can then pressurize the system and will stop running quickly. If the water pump near the end slows down, but does not stop... there is still some air in the system. Do the purge again, or check to see if there is enough water in the fresh water tank.
5- If you have done all of this and feel the pump should be at pressure... flip the on/off switch so the pump stops. Then to ON. It will most likely quit until you use a faucet. If not, do that each time you use the water pump for a faucet. Eventually the errant air pocket will be... found.
6- After traveling the fresh water tanks sloshes back and forth. It can let air, again, enter the system. Back to #2 and #3. A full fresh water tank will take care of that problem if you do not mind towing the extra weight.
7- This is a simple problem, and NOT a problem after all. The solution cannot be done in three sentences. It is a routine you will finally figure out. Some people, as smart as they might be at work... haven’t the vaguest idea of what to do when a problem arises. It is always... somebody’s else’s problem, not ignorance on their part.
8- I learned like all of you. Being ignorant, but resourceful in understanding WHY. Once this common problem is solved, you can solve adjusting your wheel bearings and brake shoes over time. Unless... it is not your problem and want to pay someone to do it for you. What works best for you is your best option. Myself... if it is not working, you cannot do much worse trying to figure it out. Sleep on it... you will have 100% of your attention to the problem and wake up refreshed and try something else.
