Shurflo water pump leaking, is there a better choice?

I'm out camping without hookups, and I just noticed a small puddle of water below my sewer bay. Looking inside it was coming down the gray tank and appeared to be clean water, so I went in and lifted the bed up, and it turns out the pump is leaking at the junction were it's screwed together. I tried to fix it by snuggling up the screws, that didn't work, so I tried some some eternabond, but it's still leaking out the screws and somewhere else. Luckily I caught it before it did any damage.

Anyway, I put a container below it and I'm going to finish my camp trip, but was just wondering if there's a better pump to get? When I look at Shurflo on Amazon, it gets really bad reviews. This one's about 10 years old, but it really hasn't had much use, which could be a problem because maybe the seals dried out?

Thanks in advance for any suggestions.

If the pump still works well otherwise, you can get a rebuild kit from Amazon for less than $30. It will include all the seals needed.

Otherwise, you can get a replacement pump for under $100. Just check the GPM and pressure and select one close.

Thank you for the reply, in the meantime I've been checking and it seems like this model 2008 is 2.8 GPM, and the model 4008 is 3 GPM, and some people say it's quieter. I could get that on Amazon for $60 shipped. I've also read that sometimes the housing cracks, so I guess I'll just order a new one.

The oem Shurflo pump in ours did the same thing but we weren't using the rig at the time. I imagine it had been leaking for a pretty good while because we ended the musty smell developing inside the rig. Had to rip out the carpet, dehumidify for a couple a few weeks, and then have new carpet installed.

Turned out the leak was coming from between the the two halves of the pump housing. I looked for a replacement and found the SeaFlo brand to be of the same specs and slightly cheaper in price. It installed without any hassle and works about the same as the Shur Flo it replaced.

Suffice it to say, I learned my lesson the hard way. I no longer leave water sitting in the tank, except for when boondocking or for emergency water storage (hurricane coming coming in).

Sorry to hear about the water damage. It looks like I dodged a bullet, most of my floor is vinyl, the carpet is on the raised areas. I left the bed up with the windows open to let it dry up.

I see that Seaflo on Amazon, 3 GPM for about the same price as their Shurflo 3 GPM, except some people mention the threads were a little different. So I may play it safe and just get another Shurflo. From what I've read they did improve it over the older version Yes mine is leaking between the housings as well. I saw another video where a guy said there's a gasket there that goes out.

Just discovered my TP valve on my water heater is leaking a little bit too, but that's no big deal. I should have replaced it years ago.

Well I ordered the Shurflo 4008 water pump last week when I was camping, and it arrived today and I just installed it. It really is about the same size as the 2008. It is a different design, and has a much thicker rubber mounting piece.

I have it mounted better than the factory did. They had it and the canister filter all crooked because they cut one hose too short and I guess had problems mounting it. They also put Teflon on the flare fittings, and the instructions say not to put Teflon or any lubricant on the plastic fittings, because you could over tighten and crack them. So I took the Teflon off. It is quieter than the 2008 and I can tell the pressure is a bit higher.

Edit: I just put the bed back down, and I have to say it is a LOT quieter. I can barely hear it at the kitchen sink, and it's almost the same in the bathroom. I think it's a combination of the way it's designed and that thicker mounting rubber. It doesn't shake all over the place like the old one did.
