Is there a plumber here who can solve the problem of air-lock in pipes?
The pipes in my bathroom seems to fail every 4 to 6 weeks because of
air-lock in the pipes and so I don't get any water in shower or taps.
Is here a permanent solution for this?
I am tired of calling plumbers all the time. Some times I use my vacuum
cleaner to suck out air from the pipes and it works and sometimes it
doesn't so I need to call a plumber.
I can see alt.home.repair is filled with garbage posts.
So it makes sense to ask the question here (???).
"hot water heating system air lock"
Heating systems that use hot water and radiators, are prone
to this, and the home owner needs to be trained how to do
the necessary maintenance.
But do they tie hydronic heating systems to a shower ?
But if so, there'd be a "real" pressure source to drive
the shower pressure. The entire hydronic system would
be pressurized to city water pressure, and the radiator
loop would be driven by a recirculation pump (not the shower).
City water or well water ?
Well water systems use a pump and a pressure tank,
to maintain tap water pressure. The pressure tank is
intended to reduce the "cycling" of the pump, so the
contacts don't wear out on the switch.
You can see an illustration of the air lock effect here,
but this is for a gravity feed. Again, not
relevant to your bathroom.
I fail to see how a city water system, with 60 psi
available, is going to air lock. (60psi would be 4atm,
1atm is 33 feet of water, 4atm is 132 feet of head
or around 13 floors high before you can't take a shower.)
This has got to be a mysterious well water system (systems I hate).
For example, the pressure tank can become water logged
(on the air side of the bladder), and need to be taken
care of. Country plumbing systems can have relatively
low water pressure, and who knows what physics become
possible then. Maybe you could manage an air lock on
the second floor of the house ? But your pressure would
likely also be well below a practical level of pressure.
With the air lock removed, maybe there still wouldn't
be sufficient pressure for a shower.
Some of those systems use a jet pump. I believe that's
a kind of aspirator (a vacuum forms over the suction
strainer and pulls water up the well, in reaction to the
main "jet" pumped down from the surface, on the right).
If your country plumber is any good, they should be
able to explain why your particular setup is prone
to the problem. Rather than just silently fixing it
each time and billing you to death.
If you're going to ask this question in alt.home.repair,
at least have the courtesy to explain to the folks there,
what kind of system you have (city/country/jetpump/immersionpump/
hydronic heating or whatever). Your question makes no sense,
without "context" and "details".

country plumbing sucks...)
