Hi all. Ok I've done some searching on the forum about this but I can't find a similar issue so I'll post it. I have an 09 PW class B. I am getting ready for a short trip tomorrow and all of a sudden my water pump is not working properly. After sanitizing my fresh water tank, I turned on the water pump and faucets to drain the fresh tank into the grey tank. I was plugged into shore power and the water pump was making it's usual noise going on and off as usual when I opened the faucets but the water flow was less than half the normal flow. It took forever to drain my 24 gallon fresh water tank into the grey tank. I looked at the pump and there are no leaks and I have not changed anything since I last used the RV and the water pump was working fine. I did not change the valve settings on my water heater because I don't have to winterize my RV here. So some thing has happened to cause a sudden decrease in the water flow. The faucets work and toilet flushes but the flow is very low now. We are leaving tomorrow on a short trip and it is Sunday so I can't get parts. But we will mostly be connected to city water at the RV park so I won't be using the water pump much except if we go to some picnic spots. Anybody got any ideas on what the problem could be? I got out the owners manual and it is a Shurflo series 2088/2093 water pump that is now about four years old but not used that much. Thanks, Don.

Check suction strainer at pump inlet.Also remove/clean all faucet aeratorsCould have stirred up junk in tank that got sucked up.Also pull pump head and clean diaphragms.

I turned on my pump and had 'no' water. Called mobile RV repair........he took off the faucet aerator and voila water. :SWhat's the law of average that sand could fill every one of those darn holes in an aerator? It did in mine.

Hey you guys are smart. I knew I joined the right forum. Guess what both the faucet aerators were plugged with junk (calcium carbonate). I know what happened, when I filled my fresh tank with water, I must have had the hose on too high and stirred up some stuff that then got into the faucet aerators and plugged both of them. I cleaned them out and got full pressure. Problem solved, but now unfortunately the water pump will not shut off with the faucets off because some of the same stuff probably got into the valves. We have very hard water here so it probably is calcium carbonate. I guess I'll also be learning how to take apart a water pump to clean the valves. I also will be flushing out and draining the fresh water tank from the spigot on the tank. Thanks all! Don

I just flushed out and drained the fresh water tank at the valve on the tank two times then added more water to the tank and took the aerators off the faucets, turned on the water pump and ran the water and after about a minute the water pump started to work fine, turning off when the faucets are off. Apparently whatever was plugging the diaphragms flushed out the faucets when the aerators were off. I replaced the aerators and all is well. From now on, due to our hard water issue, I will flush out the fresh tank and drain it at the valve twice a year. I think it will prevent the problem I had. Thanks all for the tips......Don.

You better check the intake filter at the pump. I am surprised anything would get thru it.

Ok I just unscrewed the strainer and it is totally clean. I rinsed it out and replaced it. Judging by the size of the white particles that plugged my aerators, I don't think they would have gotten through the strainer. Oh well, the system works now but I'm not really sure what the white particles on the aerators were or where they came from. Weird huh? Thanks all.

The inlet strainer helps keep debris from fresh water tank out of the pump.

Hard water can leave deposits in pump, lines, faucets etc. especially after it has gone thru water heater.....where most deposits from hard water collect.

In future after draining/flushing water heater remove aerators and then run pump to flush lines etc. then install aerators.

I'm learning here and have not had to deal with this problem before. It looks like that is called the strainer and is a wire mesh per the info on the Shurflo website. I bet mine has some of the same white deposits in it. I'll go out to the RV and remove it and clean it if it does. The junk that plugged up the pump and faucet aerators must have been a small enough diameter to get through the strainer if it is wire mesh.

Is that the white looking thing that is in what looks to be a screw on clear plastic holder. If so, does it just unscrew to remove it for cleaning or replacement? If that is a filter why would chunks of white stuff get through it and get into the pump? It is all working now, but that is a great question you ask. If it just unscrews, I'll go check it out.

I just recently drained and flushed my water heater. I also replaced my anode. Thanks for the info. It is important to do that here at least yearly because of the very hard water. Thanks.

Upon rereading your post that said you have a PleasureWay rv, I'm sure you have a Suburban water heater. I drain mine after each trip if I think the rv will be in long term storage. You'd be amazed at what junk comes out. Actually, your anode rod may be all gone.

Scarpi,
You need to remove your water heater anode if you have a Suburban and flush the junk out of the water heater. You'll be surprised at all the white little chunks of stuff that comes out. May or may not be what you're seeing and aclling calcium carbonate.
