Water Pump

[jd_cool]

I have a 1999 Holiday Rambler Endeavor
I picked up a lot of real fine sugar sand one time in my water tank and can't get it out by nunerus flushing. It messes up the pumps check valve. I have changed pumps 4 times. There is a screen filter with a sediment bulb but some sand get through to the pump and the pump starts recycling.Is there any way to get the sand out of the tank or a better filter to install at the water pump to filter out this micro fine sand?

I would try filling and dumping at the same time to get any sediment to swirl around and flow out. Is it sand or calcium/mineral deposits? Minerals can be dissolved with a solvent such as vinegar. If you can get a sample of it out of the pump strainer, leave it in vinegar overnight. If it is still there in the morning, it is probably sand.

Hi ! Welcome to IRV2! We're sure glad you joined the gang!

I don't have a solution for you but that's a great reason to always use one of the Camco in-line blue filters between the spigot and the RV! They take out the larger stuff and I have a 1/2 micron carbon-block filter under the sink with a separate faucet that we use for all consumable water.

Good luck, happy trails, and God bless!

I think I might add a whole house filter in front of the pump in the tank line if you can't get the silt out. You might be able to install with some unions so you can remove later should the tank silt clear.

Good day JD Cool,
A few good input on how to remedy your problem. I would like to add some additional suggestions:


Re: Sand in Tank

1. You stated that you have tried to flush the sand out. Most likely, you use the drain valve to accomplish this. I would suggest that you remove the line from the fresh water tank to the pump. Plug the line and fill the tank about one fourth full. Then remove the plug from the line and also open up the drain. By adding the additional line - i.e. pump line, it will "aid" in removing the sand. It my take several tries to get at much sand out of the tank. This will also remove any sand deposits that lay around the tank's connection to the pump.


Re: Preventative

2. As suggested, either use the Camco external blue filter or install a whole house filter in the coach. This will prevent further containment like sand to get into your fresh water tank.


Re: Existing Filter
3. Looks like this is not doing a good job. I would just eliminate it. You could consider using an external ICE Maker filter. This is small and available at most Big Box Stores (i.e Big Orange, Hardware, etc.). Easy connections. You will have to adapt the 1/4 inch connections on the filter to a larger size to accommodate the larger size hoses used for the tank to the pump. Some of these filter use screw fittings for connections, other use push on. I recommend getting a filter with screw fittings so that you can purchase a brass "reducer" to accomplish this.


Best or Luck

Thank you all for the wondering suggestions. I will give them a try.
