MOD Water pump upgrade with accumulator tank

[Neal]

It used to be on the site showing 10A max. I skimmed the manual and it appears to cover it. I'm getting ready to leave so min time. Also you can email Remco ([email protected]) and they are very responsive to questions sales or support.

The accumulator was added to solve a problem of water cycling at the master bathroom faucet. That issue remains, I'm going to try the accumulator tank again most likely after I get the new check valve installed, today or tomorrow.

24 hours later, new campground, haven't touched a thing, accumulator remains offline, I'm actually very pleased with this pump. Pressure is instant, no issues with needing time to prime, sound has calmed (or I have calmed) and all is good.

For those with an accumulator though, a concern is high elevation. Take for example you're going to Angel Fire, NM with nearly 9K elevation. How is this going to affect your accumulator tank? I'm guessing you should remove the pressure from it prior to going to higher elevations? Colorado even. I don't know if it will release excess pressure automatically or not.

You're overthinking! Pressure is set based on pump Pressure, not atmospheric Pressure.

At my new location, all is working great with the new water pump and it's starting to sound more like the AES pump with the lower rumble water pump noise. I swore I'd leave it alone as I'm cutting this trip short and deal with it when in storage or a later date. Well, we know I can't do that and the weather here in Charlotte is very nice today. So I decide let's get the Valterra check valve put inline just prior to the pump to ensure water does not flow backwards through the house filters and rely on the presumably failed check valve at the city water side of the filters.

Cut the hose, inserted the check valve and used pex cinch clamps to give a perfect seal to the lines using my pex cinch clamp tool which has really come in handy at times for quality plumbing work.

​

I then decided to try the accumulator tank again so I put that inline as I am getting water cycling in the master bath faucet and hence why I installed the accumulator tank to fix that, and it does. I did a leak check and sure enough I had a leak at the water pump inlet filter basket with the plastic cover not on secure enough so I may have been drawing air previously, so in the end, glad I did this today. Super simple and leak check is good at all connections and water pump tests good, doing laundry now.

Case closed. Please stop me from doing mods! But hey, this one solved a problem and was good learning. Higher flow pump and accumulator tank to prevent lower pressure draws from cycling the pump.

Now to return 42 amazon items (kidding, more like 8) and 2 Lowe's items. I should be banned soon from Amazon after last year and then this! Serial returner status!

Back tinkering at the coach, the pump is quiet, must have been just a priming issue when new and getting water into the system. Loving the accumulator tank and highly recommend it barring what REMCO says for variable pressure pumps concerned of over pressurizing your lines. That's not how it's been working, it charges the tank and shuts off. Works great! Very pleased with the 5 gpm REMCO ARV pump and REMCO accumulator tank. Any accumulator should work, it's a basic system.

Hello! Me again, yeah, the accumulator mod, yep, that's it...

So yesterday I arrived after far too long in storage and added bleach to the fresh tank to kill off predators coming through the water lines On arrival I left city water off, pump on and let water flow to the gray and then dumped, from inside of course Still strong taste and smell so filled the tank and did it again. Pump quit, oh no, although I have a spare (old Remco pump) but figured it was a thermal shutdown, it was. The pump pressure seemed odd so first thing was to remove the inlet filter. It always seems to be a source of problems and air leaks and I'm not sure why we need it when I have a carbon and sediment house filter prior to the pump. So off it went.

Still not happy with pressure, this is a 5 gpm REMCO-55AQUAJET ARV pump. It seems the accumulator is confusing the pump and as stated in the dialog from this or another thread, REMCO does not approve of an accumulator with this pump. So I bypass it. All is great again. However, I am now convinced, or strongly believing, this REMCO pump has an accumulator built in. When I power on the pump, I hear it for a few seconds as if it's charging the pressure. When I run water, it's as if the accumulator is inline, it's instant pressure. Hmmm, so this is interesting for sure but maybe now this all makes sense as to why REMCO says no to the accumulator tank option.
