Whale Check Valve - Suction or Discharge Line - Nitrile

Does the job

I have linked in a extra filter tank to my fish pond and needed a non-return valve in the flow pipe , and this worked first time very pleased.

Using on the outlet from my sump pump to stop full length of pipe draining back into the sump when float switch cuts out and seems to perform well.

Works perfectly, fitted in line, in garden hand pump, now no need for priming and not reliant on poor internal valve on pump. This fits unobtrusively within the body of the pump without problems.

Bulge pump suction

Yeah it's the real thing,happy

Was not a whale valve but a cheap copy when I tackled them about it was told it was a mix up and when I returned it a whale would be sent, received a full refund still no whale valve ? Not happy clearly some using whals great name to sell uknamed brand as they look similar , and he tried telling me they was Marine grade, I term used for grades of stainless steel ! Will not do business with this guy again informed amozon but nothing has happened the guys still selling his dodge gear

This is "ok". Not bad, but not great, just ok. Both fittings seem unusual sizes and I had to heat the 38mm pipe up to soften it in order to make it force-fit. It is not 100% fool proof either and water does slowly seep back through the valve.

Super, eingebaut schlauchschelle festgezogen , dicht und funktioniert 😊

WHALE LANDNSEA VALVOLA DI NON RITORNO DA 1" PER LAVASTOVIGLIE O LAVATRICI , ATACCO ESTERNO, MENBRANA AL SILICONE , AL INTERNO , NON A MOLLA, FA ' IL SUO LAVORO , E' IN CERTI CASI E' INDISPENASBILE, SPERO CHE NON ANDRANNO ESAURITE , SPECIALMENTE PER CHI HA' LO SCARICO A LAVELLO , VERAMENTE INDISPENASBILE , PER AQUE DI RITORNO ANCHE ' DALL' LAVELLO . STARE ATTENTI ALLA POSIZIONE VERTICALE (OBBLIGATORIA SECONDO ME) , E ALL' MONTAGGIO ,(TUBO CORRUGATO MOLTO STRETTO , DEFORMA IL TUBO CORRUGATO! USARE DEI BUONI SILICONI O COLLE PER PVC E PLASTICHE,ANCHE ' QUELLE PER MOTORI (QUARNIZIONI) . SE SI E' MOLTO AUDACI , INSERIRE UN TUBO DI PLASTICA SOTTILE MA RESISTENTEALL' INTERNO DEL TUBO ,CORRUGATO (LAVATRICI O LAVASTOVIGLE) , PER STRINGERE IL MORSETTO AVOLGI TUBO CON MOLTA FORZA: ANCHE PERCHE UN LAVOR FATTO MALE LI' FA ' GOCCIOLARE ,E POI SI DEVE RIFARE TUTTO .

Kleine Ware zum günstigen Preis. Bei wärmer Überwinterung tut das Ventil auch sicherlich mehrere Jahre ihren Dienst.
