A new pump every couple of years?
I've had 3 shurflo pumps running practically every day for the last 6 years, they're bombproof...
I also run flojet pumps in my omnitrolley 125's, they've never missed a beat either...
Buy quality, buy once.
YES I HAD A SHURFLO LAST 3 YEARS BUT THEN STARTED SQUEALING LIKE A PIG SO I REPLACED IT WITH A FLOJET WHICH IMO IS A BETTER PUMP. I ALSO BELIEVE IN BUYING QUALITY BUT ALSO DONT MIND SPENDING A FEW QUID ON UPGRADING REPLACING PARTS THAT HAVE MORE THAN PAID FOR THEM SELVES. AS I SAID EITHER KEEP OLD PUMP IN SHED FOR EMERGENCYS OR EBAY IT.
ITS LIKE CHANGING A SQUEEGEE RUBBER, YOU DONT QUITE REALISE JUST HOW NACKERED IT IS UNTIL YOU CHANGE IT!
