Hello, hooked to City water, but fresh water tank drains?

When hooked to City water we are still draining the fresh water tank. The pump works fine but we don't draw from the city water connection.
Thoughts?

Don't follow exactly what you are saying. You are hooked to city water but you are not getting any water pressure from the pedestal? Are you running the pump while you are on city water? When hooked to city water when you open the valve outside on the pedestal your RV should be pressurized by the city water system. Are you saying you have no water pressure when you are hooked to city water and the valve at the pedestal is open?

Make sure that your water pump is turned "Off"...

When you are connected to "city water", and that source is turned on, you shouldn't be using the RV's water pump at all. The water flowing through the hose into the RV will supply all the flow and pressure you need.

I surmise that you are not getting city water flow and only get water by running your pump. The pump only draws from the tank so it it’s no surprise that it’s depleting the fresh water tank supply. If your coach has a valve you use to fill the fresh water tank perhaps it has been left in the tank fill position instead of the “normal” position?

If the valve was set "wrong": the freshwater tank would continue to be re-filled...

Yes overflowing actually. but he’d still be drawing from it wouldn’t he? And wouldn’t have city water pressure. I think. Mine uses gravity fill...

According to his signature he has a 2016 Axis -- that has no valve to fill the fresh water tank -- fresh water tank is gravity fill only. (Unless a previous owner made a mod)

I wonder if he's got the problem sorted out yet?

Nope, I have not. I've arrived at my son's home and I'm staying with him too Monday.

So, if I understand correctly, if I run my pump even connected to the city water, it will pump water from the fresh tank? I've not seen too many RV parks with high enough pressure to take a nice shower without the pump running.

Yes? No?

You should not run the pump when on city water. The pump is used to pump water from the fresh water tank into the water lines. The pump puts out the same pressure as what you should be getting off the outside faucet ( about 40 to 55 psi).

What most of us have been trying to determine is do you have water pressure in your RV water lines when hooked to city water and the outside faucet turned on?

If your concern is inadequate pressure when taking a shower the best solution to this is to replace the shower head with an Oxygenics shower head. It is amazing.

Correct, unless the city water pressure is much higher than your pump output pressure - in which case it wouldn't run even if turned on.

That may be a personal preference or you may have flow restriction coming from the city water connection. The only time I have needed to run the onboard pump to boost the shower pressure is when we stay at my MIL's house where she has her well pressure at 30 psi.

Thanks everyone. That I believe solves my problem. The pump pumps water from the tank even when connected to City water.

When we continue our journey Monday I'll be testing the water pressure from the city hook up after I close the value to the fresh water tank, keep the pump off and see what happens.

Which Oxygenics shower head did you go with?

You can run the pump but it pumps only from the fresh water tank and the camp ground water will not refill the tank. If you are not getting enough pressure from the city water hookup you may have a faulty regulator or a regulated you can adjust.

Water

Hi my 2017 Windsport first time out had no water when hook up,after some frustration I found that the hose was kinked inside the rv where it hooked up to the inlet .they had put a 36 inch hose where a 20 should have been.The hose goes from the camp hook up to the main line in the rv,inside the wall.

Some thoughts onfresh water tankdrain question

On the 2016-2017 Axis 25.2 reasonably easy to see what’s going on with the fresh water tank fill.
1) City water fill through gravity fill with simple push in hose ... will fill tank … can monitor under sofa if required. When completely full the over flow will come back out right next to the gravity fill.
2) When hooked up to city water through the other “water pressure” screw-in option, I’m pretty sure there is no need to turn off any valve associated with fresh water supply. You should not have your pump turned on when on city supply. The pump will have a “check valve” to prevent filling the fresh water tank from city water pressure input. If the city water pressure is so low you have to "supercharge" with the pump on … it’s really low and of course you’ll use water from your fresh water tank … but are you trying to
back flow/raise city water line?” … suggest go with the Oxy shower head and plan to only see that low of a City Water pressure once in a blue moon. Lastly, have you checked flow direction on your in-line fresh water filter and/or checked any water reducing valve setting on a regulator if installed and/or a fixed city water reduction orifice in your own line from the city water spigot to the Axis 25.2 pressure line input? Finally make sure you have an elbow on the city water input so you do not have a hose kinked.

If you're having trouble with the City Water connection giving you enough oressure: get yourself a pressure regulator.
I've got a pair of them: 40-45 psi, and 50-55 psi. The higher pressure one worked really well with the Gerard tankless hot water system.
I'll try the 40-45 version on our next trip: we've got a Truma system that needs to be wrung out!
