Thinking caps on?

[one_dusty_hoot]

Hi Ralph,
Sometimes my thinking cap is too small won't fit!

I would start at the source since you can't find
any apparent leaks, cap or shut off the pump with
a valve, then if it don't "burp" you have a starting
point.

Still burping, problem at the pump.
No burping, isolate connections, go from there.

Ralph, I think I am with Bob, "Backflow at the pump" if you can hook
a hose to the outlet of the pump , fill it with water and close it
off. cycling on and off would reveal a pump problem.

The constant Burping in my Bus has little to do with hydrodynamics.

Ralph, how about the check valve at the city water bypass?

Ralph,

Could be air trapped in the HWT, ????

I installed a Shurflo extreme in my previous SOB, and it did just that - leaked
back through the pump diaphragms. Shurflo promptly shipped me a replacement
which did not do that. I still have the original one - they said they would send
a pickup tag, but never did!

Sounds like the Sporlan valve Ralph. If no leaks anywhere else, the
pump is cycling on to bring the pressure back up to it's set point for
the system. Just a thought, but did you check the relief valve on the
water heater? It may be weak?

Is there a pressure switch on the pump head? Can the output pressure be
adjusted at all? Is this one of those new pumps that doesn't have or
need an accumulator? If so, let us know how you like it. I am thinking
about one for my coach.

Now that Todd Jones found Tweetys.com for us, I saw that they carried
that new pump too. Maybe a good deal from them on one?

Ralph,

I just did the same modification ... took out the original pumps (2)
and the expansion tank and replaced with the ShurFlow variable speed
pump.

I have _no_ "burps" as you describe. The only time the pump switches
on is whenever a valve is opened somewhere, causing a pressure drop
in the system. Perhaps you have a leak that drips under the coach or
into a basement bay...?

Depending on the type of plumbing you have (I have polybutylene, but
that came along well after 84), you may have specific potential leak
sites where a leak of long standing may occur. In my case, the higher
pressure caused the water system emptying valve, that had a hairline
crack of long standing, to fail. No other leaks appeared.

The Sporlan valve on my system controls the flow when you flip the
'fill tank' switch. In that situation, the ShurFlow runs continuously
(that is, until I turned off the water pump switch). So, I presume
that if my Sporlan were letting a small quantity of water seep past,
that it might trigger the Shurflow from time to time.

If you have thoroughly checked all other sources of possible leaks
without finding any, then I'd say you have a Sporlan rebuild in your
future....

Ralph, You might want to check that long handled HWT drain valve that has a
pull cable on it. I chased that problem on our FC and finally discovered it was
that valve. That was after I had rebuilt the Sporlan fill valve.

Hi everyone:

Here is a fun one perhaps.

Water pump new, 5.7 gpm 65 psi

Pump cycles after initial pressure up. The cycle is a slight burp about
every 10 to 15 seconds. This normally indicates a water leak.

Kicker, I have been from one end of the pressure side of the piping and no
water leak. Only think I can think of at this point is perhaps crud in the
Sporlan valve allowing a seepage back into the system causing a slight drop
in pressure at the pump. The anti back flow valve seal is good, pulled it
and checked it out.

Ideas?

Thanks Dick:

And another good point to add to the list of troubleshooting for future
problems for all of us.

Trouble shooting points collective (add any that I missed and we will put
the list in the files section)
1. Leak back through pump
2. Anti back flow valve
3. Sporlan valve
4. fresh water drain valve
5. Burst piping/lose fittings and so forth.
6. City water input valve
7. Water heater pressure relief valve.

I have modified that valve to an air cylinder open/close now rather then
the cable pull system. Problem was the Sporlan valve
