Our 05' 40fdts did not come with all the manuals when I bought it last summer. We have always been in RV parks with it until now. Getting it ready for our first dry camping outing, I sanitized the water tank. I then turned on the pump, got very low flow and the pump would not shut off. I naturally figured "bad pump". $260.00 and much contortion later, I had the new pump in. With a smile of satisfaction, I turned on the new pump and PRESTO!! It did the same thing as the old pump. Long story short, after flooding the basement trying to track down the problem, I discovered that once the fresh tank is full, the select lever for "fresh water fill" and "city water" must be in the "city water" position. Now, perfect water pressure and the pump shuts right off when the faucet is turned off. Expensive lesson, but hope it will be of use to someone else. At least I have a good spare pump now!

Expensive lesson, but you're not alone, and having a spare is not a bad thing when you have a ShurFlo pump. I've gone thru 3, but only had to pay for 1. The rest were under warranty.

Same as our DSDP, and yes, it took me a while to figure it out, but I didn't flood anything.

Hmm-mmm......

Now where have I heard that story before?.....

Then forgot about it and heard it again?.......

Don't forget to purge all the air from the system too!

What is the best way to purge the air?

Start at the faucet closest to the water tank and let the water run until you get a steady flow. Proceed to the next closest faucet and repeat until all the faucets run in a steady flow.

Thanks!

The air purge is not necessary save that you do it automatically as part of the sanatize. And you WILL do it the first time you open a faucet or flush.

The only reason to make a point of doing it is that if you forget a faucet. the first time it's opened it's going to be a bit...er... dramatic. (Supttering and spitting and blasting water everywhere but straight) As you will see when you do it on purpose.

If you don't get all the air out of the system, it could and sometimes will play havic with your pump. You can also open the low-point drains to get trapped air out.

For people that want or need to replace their water pumps, do NOT waste your money on Shur-Flo pumps.

Aqua-Jet will give you better GPM flow and higher pressure. Mine has been used problem free since new when it was installed 10 years ago.
