No Running Water - 2018 Jayco Greyhawk 29MVP

[JaycoNewbies]

After sitting since February, we wanted to sanitize the fresh water tank. We followed all the steps, but the bleach water mix wouldn't go into the intake. So, we tried just filling the fresh water tank. Still nothing. Then, we just set it up as though we were at the campground and tried running faucets directly from city water. Other than a lot of air and a few drips - nothing. We have no idea what's going on. Help!

What intake? Fresh water fill does not work? Is it gravity feed or city water valve controlled? 'Still nothing' does not help us understand.

Start at the beginning. Is there a good water supply with 40-50 lbs pressure? Are the valves set correctly? Are the set screws on the valves secure and when the valve handle is turned is the valve actually operating.? Do you have a water heater that needed to be filled? Do you have a inline filter that has blocking valves? Are these open? Is the filter clean?

Since you said you are getting air purging I would think that you might have weak water supply and it is taking awhile to fill the water heater.

The more details of what you have tried and what is occurring the better for specific help on your issue.

X2, if the water heater is empty, it can take a while to fill. Most of the time when I fill my water heater, all the faucets are turned off, and from the outside of the rig, I open up the pressure relief valve and let the water run until the tank is spewing water all over itself. Then I go inside and purge the air out of the rest of the lines. If you are using the water pump, there is not much pressure or volume, so it will take 3-5 minutes to fill the water heater.

These are the steps we were following. When we realized the sanitizing solution wasn't being siphoned into the tank, we then tried filling the fresh water tank, using the city water intake. We have a tankless water heater. Finally, we bypassed the fresh tank, and did what we would do in a campground with water - hook up to city water, changed the settings at the utility center, and still had no water. Thanks very much for your help.

How To Sanitize
1. Turn water heater power OFF (storage style-both electric and LP gas switches; tank lesswater heater turn power switch OFF).

2. Set the bypass valves to BYPASS (refer to Water Heater Bypass Valves section).

3. Level the RV and drain the fresh water system (see Draining the Fresh Water System).

4. Close the low point drain valves and the fresh water tank drain valve.

5. If the RV has a cartridge type water filter it must be removed and bypassed using the (supplied) bypass tube. Sanitizer should never be allowed into a water filter.

6. Prepare a chlorine solution using 1/4 cup of household bleach (sodium hypochlorite solution) to one gallon (3.785 liters) of water in a container. Prepare one gallon of solution for every 15 gallons of tank capacity. This will result in a residual chlorine concentration of 50 ppm in the water system.
If a 100-ppm concentration is required, use ½ cup of household bleach with one gallon of water to prepare the chlorine solution. One gallon of the solution should be used for each 15 gallons of tank capacity.

7. Put the sanitizer solution in the fresh water tank. Insert one end of a hose (or funnel) in the gravity fill inlet; insert the other end into a container holding the chlorine solution. Do not use your non-toxic drinking water hose. Pour the chlorine solution into the gravity fill.

8. Remove the hose (or funnel) and container used to pour the chlorine solution, and continue filling the fresh water tank with clean (potable) water until tank is full. Pour fresh water into the gravity fill inlet until tank is completely full. After the recommended amount of sanitizing solution is in the tank, the water tank is full, and water filter has been removed and bypassed, turn the pump ON which sends sanitizer into the water lines.

9. Open all hot water faucets one by one until water begins to flow continuously and a chlorine smell is noticeable. Include outside shower faucets (if so equipped).

10. Close the hot water faucets and repeat opening all cold water faucets one by one until you smell chlorine. Include outside shower faucets (if so equipped) and toilet.

11. Turn OFF the water pump.

12. Let the solution remain in the tank & lines for at least four hours when disinfecting with 50-PPM residual chlorine. If a shorter time period is desired, then a 100-PPM chlorine concentration should be permitted to sit in the system for at least one hour.

13. After the required period, drain the chlorine solution from the fresh water system. Since the water heater was bypassed there should be no sanitizer in the (storage) tank water heater. Rinse the system with fresh water

14. Fill the fresh water tank full of clean (potable) water. Fill fresh water tank from an external container. Pour fresh water into the gravity fill inlet using a hose (or funnel).

15. Power to water heater should be OFF (both switches: electric & LP gas). When the fresh water tank is full, turn the pump ON to send water through the lines.

16. Run water through all faucets (hot & cold, including outside shower) until chlorine smell is gone. Turn faucets and outside shower off, turn pump OFF.

17. Then, drain the fresh water system again (see Draining the Fresh Water System).

18. Set water heater bypass to NORMAL: Allows water into the water heater. Replace the water heater drain plug.

19. Refill the fresh water tank with fresh water again and when water heater is full of water, turn the water heater power ON.

Did you flip the cone screen at the hose connection? There is a check a valve there and sometimes the pump can't overcome the spring. Flip the cone screen to push the valve open. Don't forget to flip it back.

For your MH, #8 really is not a valid statement, as you do not have a gravity fill port on your MH. If I recall correctly you need to flip your valves at the command center to 1 & 4. Flip the filter screen hose washer over at your city water hose connection. The filter screen hose washer presses on the check valve, allowing the pump to suck the concentrated water into the tank, via a short hose.

When you have all the concentrated solution into the tank, flip the filter screen washer over, so the check valve can re-seat. Connect your hose to the city water source, and continue to fill the FW tank.

I suspect your filter screen washer might be pressing on the check valve, hence the pump is trying to draw air into the system verse pull water up and out of the tank.

Thanks, everyone! We put all of your knowledge together and the problem is solved.

Curious, what was the issue?

[JaycoNewbies]

A combination of things. We needed to flip the screen hose washer. We also changed which water supply we used. We think the one we were trying may have been too low. with those two changes - problem solved! Thanks!
