Moved House - Gained Pond!!

[Joe_Ham]

Hi all,

Recently moved into a new house with 2 ponds out back, a small in ground and a larger above ground 1. The small one has 2 koi and a couple goldfish and I’m looking to transfer them into the big one (small child - safety risk) however theres no hardware on the big one (although does have electric to it).
The big one has a bottom drain with a gate waste valve (picture attached). I have quite a limited budget so was hoping to stick an all in one pump for the time being just so i can get the fish moved and fill the other pond in however when I filled the pond, it drained to about half way through the waste valve (even though it was closed). Should this happen? Or have I a faulty waste valve? If this should happen, whats my best cost effective (not permanent, just so I can have my lad out in the garden in summer without worry) solution to get this pond going!
Pond dimensions 190x150x120cm

TIA
Joe

and welcome @Joe_Ham
So you drained all the good water out of the big pond? Now you are gonna have to get that water conditioned to be good for the fish before you put them in there. Not sure why the pond is draining tho.

No, I didn’t drain it, the previous owner must have done it (unfortunately the previous owner now deceased, not really anyone I can ask!)

Welcome to the forum!

I can't help with waste valves etc, don't have them, but somebody will chime in.
