winterisation of heater -question re leak.urgent

[chirpy]

I have a Optipac 2 heater installed 6 years ago in new pool.

I have managed to date to winterise and as directed by supplier of pool i.e. closed 2 valves for water that goes from pool V2  to heater and back via V3 to chlorinater and pool.

I have disconnected both connection union fittings to drain this circuit and also the two connections  outside pool equipment house where the hoses enter the heater.

After water was drained I checked for any leaks  by switching on the ciculation pump as I had also cleaned the chlorinater .

 Before reconnecting the 4 fittings above I  found water was coming from the hose from the pool!!!!!!!!!!!!!!!!!!!

I.E. UP TOWARDS THE STOP GATE .-THE WATER STOPS WHEN I SWITCH OFF PUMP.

Why can water be pumped when not connected to the pump circuit??

I HAVE A DILEMA AS I NEED TO PUMP WATER DURING THE NIGHT AS FREEZING TEMPERATURES ARE HERE NOW AND I DO NOT DRAIN ALL EQUIPMENT ETC.

WILL I LOOSE WATER AND PUT SOME INTO HEATER WHICH THEN HAS A CHANCE TO BE FROZEN AND DAMAGED.

 

HELP PLEASE.

Is your local technique and heater circuit above or below the water line.

LOWEST POINT OF WATER HOSES IS 36 CM BELOW SKIMMER LEVEL OF POOL.

The equipment is in concrete housing and heater outside of it.when connection joined again no water leaking now as taps in off posittion but i had noticed some water at the outside connections to heater and worried some water may enter here.Maybe a little water not completely drained from heater system?

This will always be a problem when the Local technique is sited lower

than water level; vis you cannot effectively drain all the pipes, as

even if the you drop the level in the pool below return prise then you

still have the Bond de font(bottom drain) pushing water pushing on the

valves. Mostly as this buried deep then it tends not to be a problem,

but it it surfaces then you'll be fiting to keep it from freezing. SO

if you've stopped the water at the valave line  in front of the

pump and opened the pump drain, filter drain and emptied the lines

returing to the pool then I cannot see that you will have any

difficulties. The Heat pump should be empty.

If you need specific help then PM me with some pics and i'll try to help more.

Note I  do not drain pump as I circulate all year and especially at night if chance of freezing .
