Replace a Sureflow 5.7 with?

I am tired of replacing Shurflo 5.7 pumps, even if I am replacing them under warranty. Any recommendations for another pump that has approx. the same output rate but might be a little more reliable?

Thanks

Excellent water pump replacement

This works for me. Froze and cracked the first one after 7 1/2 yrs of service. Replaced with another Aquajet

Aquajet ES delivering 80 psi at 3.5 GPM using up to 6 1/2 amps.

Shurflo 5.7 pump Pump shut-off pressure is 65 PSI, Minimum power requirement is 15 AMPS, at 5.7 GPM

Big difference in GPM when wanting a good shower.
But the Aquajet ES with 15 more PSI might make it feel, more water is coming out.

My 5.7 is now at almost 7 years old with no problems.

This Aquajet pump delivering 80 psi at 5.3 GPM using up to 10 amps is closer to the 5.7

Just saw a picture of the smartsensor 5.7, and something looks different about it.

Now what is the problem, they have 3 years warranty, last about 14 months, so it's like getting a new WP free, it takes about 30 minutes to change it, now what is wrong with that again? To get it realaced for free, you just have to take it back to where you purchased it, or call Shurflo and they will arange for a new one.

Not the same model, but I've switched from Shurflo because of the frequent failures also, 3rd failure on 6 year old coach. . Went with an Aquajet in March, haven't had it long enough to know if it will last.

My Shurflo failed on me as like a lot of guys here. I decided to put my 2.8 back in rather than find a high flow replacement.
More often than not, I'm hooked up to an outside water supply so it's not that big of a deal. The lack of pressure and a little noise just isn't a big enough deal at those few times I have to use the pump.
I just bought it to what was being said about the high flow and pressure. I wish I hadn't.

Some folks do not mind constantly changing a poorly designed product - yup, its easy to replace. Well, its easy if you add a shutoff valve (to compensate for a constantly failing pump) or do most of your parking where there are hookups. Pump failure out in the desert or in some National Forest is a fairly large pain in the, well, you no where that pain is! And the 5.7 pumps do not only fail because of the internal pressure sensing devices, I have had the main seal start leaking, and even the fancy quick disconnect come apart.

So it is time for me to find a new manufacturer. Thanks for the suggestions, I will be checking out the Aquajet in a couple days.

Easier to switch to a reliable product than to tell my wife that she can't shower, brush her teeth, or flush the toilet while at a track day with only portable toilets available. Believe me, that won't happen again!

Would someone who has replaced a ShurFlo with the AquaJet please describe what (if any) modifications are required when performing a replacement?

Mounting Bolt Pattern / Position -
Input & Output Lines / Fittings -
DC Power Connection / Connector -

It appears my ShurFlo pump is running but the volume / pressure level seems to be quite lower than usual. I'm ready to switch!

Thanks!

Ours was aquajet to aquajet. WRV scabbed on a piece of 3/4" plywood to the frame rail for mounting. The trick here is to use short enough hex head screws so as not to contact the steel frame rail underneath. Adding another 1/2" piece of plywood would be helpful so that screws do not hit the frame rail. The wiring should be ok for length and size. You may need a couple of PEX fittings and longer piece of PEX tubing available at Home Depot under another name. Our mounting bolts were over tightened and the mounting isolation rubber grommets mostly ineffective. Don't count on an rv repair shop to correct any of the WRV errors.
Send a PM if you have any questions.

All - Since all WP's have parts made in China, the quality of any of them in my mind is suspect. I don't full time, and we carry a spare pump, so we are covered. Yes, it can be a pain to change in the middle of the desert, but I don't believe you are going to find any pump which will last years and years like they used too. You can blame all this on our government for letting quality products and jobs go overseas or disappear completely. And that is my two cents worth.

Not sure why we want to blame the government for all failures, it is simply not true. All of us (me included) who shop and demand the lowest price (walmart) are to blame as manufactures have found that sweat shop labor in east asia is much cheaper than paying decent wages here......so off the jobs go. just my opinion, obviously not shared by everyone but we all are entitled and I shared mine, sorry for the rant.

Ann N Gene - All - Yep, that is part of it, environmental is more of it, government is part of it. We stopped long ago buying anything that was made in china if there was an alternative. Sometimes there is not, so we suck it up and buy it. I have sent parts back which were made in China (Fluke Amp Clamp type MM), and sought out higher priced others. Its hard sometimes to find equipment/parts which are made here. Picked up a nice little compressor from Porter Cable, made of foreign and US made parts, oil-less, but it's compact and hits 150 PSI, and for how I use it works great. Purchased the more expensive Fein Multimaster tool advertised on TV because it was made in Germany, over the others (harbor freight, sears, portor cable, etc) all of which are made in china. It's great does exactly what they say, light and east to get into tight places.
