I have been involved in the Koi hobby for many years, and never sustained injuries until this weekend.

I rushed home from my farm to do back washes of all my sand filters at Table View. In my hurry, I opened one of the sand filters without first putting the multi port valve on backwash.

What I did not realize was that one of the filters ran dry, and the pump was sucking air in stead of water, building up a huge pressure in the 3 bag filter over hours.

The moment I released the cap, it exploded in my face, the result as follows:



Morel of the story, ALWAYS first put your multi port valve on backwash before your open your sand filter. It can be a very dangerous piece of equipment.

I hope you will get well soon.

I also open the filters from time to time without switching to back-wash.

By the looks of it you nearly-nearly lost your eye. Is your sight damaged at all?

Thanks for the warning.

Lekker shiner you got yourself there. Luckily it was daytime or the missus might have suspected you of brawling?!

But seriously, thanks for the warning.

I thought for a moment I lost my eye when I saw blood dripping from my hand and the sound was horrifying.

They eye is opening again and apart from a bit of double vision, it is fine. Could have been worse.

Jissim dit lyk baie seer ... sterkte.

Goeie genade tog. Dit kon 'n baie lelike dinge gewees het. Wys jou nou net hoe vinnig gebeur 'n ongeluk. Hoop jou oog lyk binnekort sommer stukke beter en dat jou visie ook heeltemal sal opklaar.

Hi,
Sorry to see this - goodness you were lucky.

A question or two don't you switch off your pump or pumps when opening the filter?

If the filter was under pressure how did you manage to open it?

Please don't make too much of this as you may give William more anti- sand filter ammunition ....

Paul,

dis 'n mooi een wat jy daar het!

Hell, jy het my uitkyk op sandfilters nou net weer laat aanpas.
Ek se nog altyd sandfilters is nie vir lui ouens nie, maar nou laat jy my wonder

Dom ouens is gewoonlik nie lui nie

Wat ons nie sal deur maak vir ons vis nie!

Gou gesond word Paul!

Vir die sand filter manne;

Die Pool Rite S-3000 & S-4000 sand filters in die prentjie hier bo werk baie lekker op koi damme. Die tiepe sand filter gebruik die interne druk om die sand filter se opening van binne af teseel....so daar is geen klampe of skroewe wat kan breek nie. En jy kan hom nie oop maak terwyl daar druk binne in is nie. Om hom oop temaak moet die druk binnein eers verlos word deur die pomp af tesit of die valve na waste toe te draai. Waneer die druk verlos is val die deksel na binne en die dwars arm aan die bo kant keer dat hy inval...en as die krag af gegaan het is die filter automaties oop en nie onder druk nie...as die krag weer aan kom dan druk die water binne weer die deksel in die gat. Mens gebruik glad nie die skroef op die deksel nie.

Die model nommers is dieselfde by swembad en koi winkels maar die interne meganismis verskil.

In my eie opinie is dit 'n beter kopie as die Speck Koi sand filter en hulle is heelwat goedkoper. My S-3000 was R 999 3 jaar gelede. Mens kry hulle of in plastiek of veselglas.

That must of been quite sore, hope your eye heals quickly.
