Hi guys

Just after some advice from anybody who knows about evaporative air con?

Basically, my unit is working ok, but I'm finding that even a few days after its
last use, we are getting a trickle of water dripping from the pipe, that usually expels a whole lot of water when you turn the unit off (if that makes any sense??????)
Anyway, just wandering if this is normal with this kind of system and where the water is coming from?

ps the trickling water stops, when I turn the unit on?

Cheers

Steve

They run on a reservoir of water which is controlled by a float
(same as a toilet cistern ) if the float sets its self too high water will leak via an overflow.
Or it could be the reverse ,if it is a self emptying (ie Brivis) when shut off
the float isna quite closing the valve.

As mulben quite correctly states, there's a good chance it's a problem with the float valve. Though it could also be a build-up of mud in the resevoir.

When was the last time you had the unit maintained ?

Cheers guys, will climb in the loft and have a look.

Been in the house about 8 months, haven't had the system serviced myself,
so not sure how long since it was last done?

how will you do it from the loft,? it's on the roof.

mulben

There should be a copper pipe on an outside wall with a gate valve on it,running up into your eaves.
This is usually near the overflow pipe.
Shut it off and see if the leak stops at the same time.If it does the unit is a self emptying type.
When you said it purges after being shut off -its also what a self emptying unit does
It shouldn't be in the loft ,usually on the roof unless its a commercial unit which are on the ground.

There is a plastic pipe, where the water comes out, but no gate valve.The pipes goes up into the eves and I presume through the loft and to the unit, which is on the roof. I presumed some of the relevant points to check, valves etc would be between the eves and were the plastic pipe enters the unit on the roof.
From what you say, I guess it must be the self emptying type
Thanks for the info

mulben

The gate valve must be just under the unit on the roof then (there has to be one ) If you can , check the float is shutting the water flow off when the unit is not in use.
