Default fresh water pump problem

I have been reading this forum for quite some time now, and I'm very impressed with everyones knowledge and willingness to share it. It seems that most every question that is presented usually gets answered or figured out. I have a Par fresh water pump that is belt driven and I suspect it to be the original. I know they are quality and all of that, but it's now not working. It was running very slowly, even with the belt off, so I removed it and hooked it up directly to a battery charger and got the same results. I think I want to replace it with a newer style, I've always have had weak presser in the shower when using the pump. Anyone have a suggestion on what kind to replace it with?

Sam,

I would recommend the Shurflo Extreme 5.7. It's what I'm using and I'm happy with it. Many other forum members use it too. Great pressure and volume in the shower with it.

Sam,

This is a common issue. Not a big deal. These pumps have a short life span relative to the Bird itself. There are a variety of options. If you plan on doing dry camping, I would not recommend the new high volume pumps.

The Shurflo products seem to dominate the market and are available at numerous locations. Also, the new pumps turn off automatically when there is no demand. As long as your connections are good, this is a convenient feature. Here is a link to one source.

Hi Sam--
I replaced the old belt-driven Par in our '83 with a Shurflo Extreme 4.0. This gives us plenty of water pressure, and is not as loud as the old one. You can see in the picture where the old one used to sit, and that I attached the new one to the outside wall.

Also check out aquaTec pumps. I have the aquaJet 3.5 pump and like it.

Thanks for all your input, I think I might go with either the Shurflo 4.0 or 5.7. I guess I can get rid of my accumulator tank if I go with either of these,Right?

I think the expansion tank is not recommended with the Shurflo extreme pumps. I took ours out when I installed the pump.

Thanks Jeff. By the way, that 83 FC you have is a very nice bird. I remember when it was for sale. I bought mine from the brother of the guy you bought yours from.

On another thread, someone was saying that you could leave the accumulator tank in place. However, I don't see much point to it. I removed my accumulator tank when I installed the Shurflo 5.7 variable speed pump. (Be sure to get the high-volume filter screen with the pump.) I've been very pleased with the performance of the 5.7 pump -- but for an older 'bird a 4.0 gpm pump might be a better choice. The 5.7 delivers about 65 psi to the water system, IIRC, the 4.0 gives about 45 psi -- more inline with what the plumbing is accustomed to seeing. I note that the Microphor air-operated toilet can act up at pressure above 50 psi. (I've had some issues there, but a pressure reducer on the inlet line to the Microphor takes care of that.)

To see some photos of my installation, see:
