any one else running this pump? its an excellent pump, got mine installed this weekend and its pretty much just like home water pressure!
will take some pix of the setup but got it nested neatly in place of the stock pump, though its slightly larger.
The whole setup, pump, strainer, lines and fitings for about $235, the variable speed adjusts for tap demand, and eliminates the need for the pressure switch and provides enough pressure to run all taps simultainously, though the tank will soon empty if you do that too much hehe
I recommend this pump for anyone who wants at home water pressure anywhere

I bought two of those two or three years back; one for my boat
and one for my travel trailer. I still haven't installed the one
in my RV, but I really like the one that I installed in the boat.
The only trouble there is that at full tilt, it pops the breaker,
so I just have to remember not to turn water on full bore.
Maybe I'll get around to installing the remaining pump into my
travel trailer this year.
I recommend them!

I am on my second one. The first one leaked from the git-go from the
housing, not a fitting I could repair. The second one has performed
flawlessly. I also run an accumulator. Quieter by far than the OEM
one.

Shan,
It is a nice pump, but somewhat pricey. Most popular pump used for the GMC
is probably the Shurflo 2088. I have installed a number of these pumps

Do a lot of you guys use them?
Will it reduce the noise of my stock water pump?

pretty much anything will reduce the noise of the stock pump. That bad boy has run for 30+ years, which is very impressive, but that design is pretty loud compared to a modern pump. I use the quietflo pump and love it. I don't really need the size of the pump mentioned on this thread, so the smaller quietflo is great.
Thanks,

I installed a Home Depot unit 2 years ago in an attempt to quieten our shurflo. I took it back out. Was not that much better and took up a lot of room. Quiet pumps are best answer, in my opinion.

The point of an accumulator is not to quiet down the pump. It is to keep the pump from cycling. Most of the time I do not leave the pump on any more unless I am taking a shower or washing dishes. I just turn it on until it fills up the accumulator. You can flush the toilet at night and the pump does not run waking up others in the coach.
I always notice other people's coaches when their pump is stuttering every time they turn on the faucet. With an accumulator this does not happen and the pump will last a lot longer.

As with when we were sailing, we will often go for three to five days (and sometimes more) without taking on fresh water. One of the problems with a pressure water system is that if a leak develops and you don't catch it, you can pump all your fresh water - out - into the black tank - overboard - and none of those is a desirable situation. With a noisy pump, you know that water is leaving.
OK - well yes, if someone flushes the pot and washes hands in the middle of the night, the pump runs. That's OK Too, as long as I hear the pump stop running.
I realize that fresh water is not as valuable to this group as it has been to me for most of my life.
Yes, I know I'm paranoid, but I have that it served me well so far.

If you did not set you tank's air pressure to match your system it will not accumulate anything. Did you do that when you installed it?
Set the tank air pressure 2 PSI below your pump's turn on point as per the instructions that came with the tank. My home and my airport expansion tanks are set to 28 PSI with the well pump switch set to 30 on and 50 off. If you bought a tank from HD or Lowes it is probably pre-charged to something close to 28. Your GMC system runs considerably lower pressure. I do not remember any more what that is on a GMC water system because I installed it several years ago and have never had to look at it since. I'm sure it is below 30 PSI and is probably 15 on and 20 off. If you install a tank and the air pressure in the tank 28 PSI with the pump shut off only 20 PSI then it will not accumulate anything.
It is the same principal used on all home well systems. Well pumps are rated in cycles (the number of times it turns off and on). That is why every well system I have ever seen has an accumulator.
The expansion tank is one of the easiest and best upgrades I did to my GMC. Find a location to put it anywhere in the coach. Under the bathroom sink near the hot water heater is a good place. Put in a TEE in any cold water line and run it to the tank. Set the air pressure and you are done.
Everyone should have one.

I've never used one of the little "RV" accumulators but I can't imagine them
being worth carrying to the checkout counter, much less paying for or
installing -- they're simply too little to accomplish much more than
suppress a little of the surging sometimes experienced with pumped systems.
For long pump cycle times, including a silent toilet flush or two, you need
more capacity. With a small home-type accumulator (2 gallons?), which is
easy to stash away in an inaccessible location, home-like water flow is
easily achieved. The 2 g. tanks cost little more than the little RV
"softballs".
We would not give up the accumulator to regain the space it occupies, even
in the 23'

My first try at putting the adventures of Terry together in MS Word
resulted in a product too large to be accepted. I hope that putting
it into .txt format will allow it to proceed.

Best Laid Plans
(A Narrative)
By Terry Skinner
Best laid plans, Page one:
As some already know, on the tenth I flew down to Little Rock AR to
drive a 23’ GMC back up here for a friend. Premise from the owner
was that outside of needing a new battery it was ready to go.
From Little Rock I drove 100 miles east to a little town called
Preston, then 10 miles on a country road to a muddy, washed out
drive way.
At the end of the driveway was a small barn just large enough to
contain the GMC. Then the fun started. For 10 years this coach has
been setting. The electrical cabinet was infested with pack rats.
So the first couple days were invested in cleaning them out. Two
batteries were purchased at the local Wal-Mart only 20 miles away in
the next town. Then another day spent on trying to get her started.
Once she started I discovered the exhaust gasket was blown at the
manifold. Two days waiting for one to be shipped in (it was snowing
in Little Rock and that shut down the shipping). Big day came, GMC
running (did I mention that it was non-stop raining and the yard was
so soggy that I got the rental car stuck?)
I backed as far back into the barn as I could. Jacked the air bags
up as high as I could (did I mention the compressor was not working
so I installed Schrader valves) laid sheets of plywood across the
yard and came out full tilt, across the yard, down the driveway,
thru the wash-out (that I had shoveled gravel into) and out into the
road. And that was just the start of my trip home. Terry
PS: You won’t believe page two.
Best laid plans, Page two:
As soon as that GMC and I hit the end of the driveway we were on the
road. Never heard from the PO again. Not even a call to see if I
was making progress. First stop was a truck stop to set the bags
and air up the tires and don’t forget gas. Tires were from 20 lbs
to 75 lbs. They looked like new but were 10 years old. Roll the
dice and hit the road again. I wanted to get thru Dallas because
snow was in the forecast for the next day. Engine was running good
outside of every now and then it would stop running. No big thing,
just change from the main tank to the reserve and “keep on
trucking.” By evening this was getting to be a regular thing so
I stopped at a KOA campground. Tried to plug in the power cord and
there were sparks everywhere. More evidence of the pack rats. They
had chewed thru both 120vac and 12vdc wiring. That was a cold
night. Next morning I ventured on into Dallas to find a set of 12v
magnetic taillights. Just as I got into the busiest part of town
one of the water hoses that run to the back bursts spewing the
coolant all over the road. Did I mention that there was a foot of
snow on the ground?
Lucky for me someone had installed gate valves in the heater hoses
and I was able to close off the offending hoses and fill the
radiator back up. This was done with a 16 oz coke bottle and a
ditch full of rain/snow water. I took the southern route around
Dallas looking for a Home Depot to get fittings to fix the heater
hose. It was cold in that GMC. By night fall I was west of Fort
Worth and stopped at an RV park where I could spend the night. Next
morning I wired in the magnetic tail lights, hooked up an electric
pump to help the gas up to the engine and tried to get the propane
furnace to work. After installing $42 worth of propane the fill
spout started leaking. That was scary!!
Banging on it with a 2 by 4 and jabbing with a screwdriver I got the
leaking stopped. Furnace still didn’t work. What else can go
wrong?? Terry
PS: Page three is better yet.
Best laid plans, Page three:
Another day another dollar or something like that. Next stop was
Monahans, Texas. All day long the engine is giving me trouble.
Any kind of a grade and the engine would start missing and coughing
and sputtering. By this time I am running on the reserve (front
tank) and switching to the main (rear tank) when it tries to quit.
Several times, when it quit, I looked down into the carburetor and
gas was bubbling out the jets. Maybe one of the mufflers is plugged
and over heating the crossover. Or maybe it could be the ignition
control module. I always carry a spare in my GMC. Or maybe it
could be the plugs are gapped too far. This is a ’73 and back then
it was 0.065, now we use 0.045. Don’t forget the fuel filter in the
carb inlet. Plus a couple in line filters to install at each tank.
That auto parts store made a fortune off me. I spent two days in
the RV park next to the golf course changing these things. Even
found a muffler shop that would cut out the original mufflers and
replace them with straight pipes. That cost me $165. Next day
here we go again. For those that have not been in this part of
Texas it is flatter than a pancake and we are running at 65 to 70
MPH. No more snow; nor rain for that matter. Then we started
getting close to El Paso and the GMC started acting up. Same thing;
switching tanks back and forth. By the time I got thru El Paso the
GMC would only run on the reserve tank and then only down hill.
What a mess. I found an RV park in Las Cruces and spent the night.
Next day I rigged a 5 gallon can inside with a 3/8 hose running out
the window and down to the selector valve. That way I could run
on the reserve tank and switch to the 5 gallon tank when she was
acting up. What did you expect from an alley mechanic?? Yes, I
used lots of duct tape to hold it in place. Terry
PS: Tomorrow will be Page four and a little easier.
Best laid plans, Page four:
In the process of hooking up this 5 gallon tank inside I managed to
make a 2 inch cut in my right hand between the thumb and first
finger. Talk about stupid. No one else to blame. Not even a wife
to feel sorry for me. Couldn’t find a hospital or clinic. Did it
with my own pocket knife. To hell with it, the GMC is running good
so I took off west bound. Not ten miles out of town is a check
station manned by the border patrol. These guys took me in, washed
my “wound” and bandaged my hand. Great guys!! If I could have
found a donut shop close by I would have taken a couple dozen back
to them. If anyone is going thru there drop off a couple dozen
for me and I will gladly repay you. I pressed on to Phoenix and
my brother’s house in Chandler. Switching back and forth between
the forward tank and the 5 gallon tank inside. Nerve racking to say
the least. Highway 10 goes thru Benson AZ, which isn’t too far from
Steve Ferguson’s place. I was seriously thinking about stopping
there but elected to continue on. Two reasons: Not sure what was
wrong and I wanted a big city to find parts. Second, my wife was
flying in to meet me and celebrate my birthday. Coughing and
wheezing that GMC carried me into Chandler late that night. You
cannot imagine what a pleasure it was to take a shower and crawl
into a queen size bed. Terry
PS: Next will be page Five and the work starts.
Best laid plans, Page five:
Next morning I called around the Phoenix area to see if any of the
local GMCers had a set of ramps. None were available so off to
Home Depot for 2 by 10s and 2 by 4s. That got me up 10 inches and
with a little extra air in the bags there was enough room to pull
the tanks. Started with the front tank. With a creeper and floor
jack from Harbor Freight it was a breeze, a walk in the park.
Nothing wrong with the supply hoses. Pulled the sender out and the
“sock” over the end of the fuel pick-up was partially plugged.
On a hard pull the engine would pull more gas, collapsing the sock
and cutting off the supply. My addition of an electric pump just
aggravated the situation by pulling more fuel and collapsing the
sock more. I called Steve Ferguson and he concurred with me. Throw
the sock away!! Now the back tank. When it came down the hoses,
both vent and supply were collapsed. Pinched between the floor and
the tank. Not even in the groove where they belonged. I replaced
the rubber hoses with 3/8 inch steel brake lines and new clamps.
Tanks went back up so easy with the steel tubes and everything duct
taped into place. Got the vents worked out and going to the right
places. So Cool!! Poured 10 gallons into the tanks and looked
underneath. Rear tank was leaking. What now?? Sure enough
manhandling the rear tank in and out must have broken loose the
rust in the bottom and now gas was seeping out. Does it ever
end?? Terry
PS: Next is page Six and the trip home.
Best laid plans, Page six:
OK, that’s it, I’m done. It’s time to go home. I blocked off the
back tank with a 3/4 inch PVC cap in the fill spout and a couple
pieces of doweling plugging the supply and vent hoses. Front tank
works well and carries 25 gallons; my 5-gallon tank would be my
reserve. Wednesday afternoon I loaded everything in the GMC
including the wife; dropped her off at the airport to fly home and
I headed out I-10 for LA. Spent the first night at Quartzsite.
Everything was working well. Was getting about 10 miles to the
gallon so every 200 miles was a gas stop (more or less). Spent the
next night in a truck stop just before Bakersfield. Next day was
spent driving I-5 up as far as Williams. Lucky for me the wife was
back home keeping a weather eye out for me. The forecast was for
12 inches of snow in Southern Oregon along the I-5 route. Now I
don’t know about you but that snow and slush I had back in Dallas
was more than enough. Williams, CA was a hard left and out to the
coast and 101 North. Spent one night in Ukiah, CA and one night
in Bandon, OR. Saturday night on Feb. 27th 2010 I got to sleep in
my own bed next to my lovely wife. Glad to be home. Terry
PS: Next is the epilogue, what I would do different.
