As fulltimers my rational was that we should have the best equipment we could afford, no short cuts.. performance, reliability and longevity being the criteria. To that end I decided to upgrade the water pump and retain the old pump as a standby, a pump failing in the back of beyond is not fun.. I looked at several makes and chose a Shurflo Smart Sensor 5.7 not cheap at around £200, but as one members signature says .. . and I tend to agree .. This is supposed to be the best, vairiable flow rate, no more scalding or freezing showers when someone else flushes the toilet .. in a nutshell .. the dogs whotsits. I bought one from Linda before setting off for Europe but a couple of months later it packed up.. spluttered and died.. so I refitted the old pump and decided to wait until I was back in the UK to return it. On returning home I contacted Linda who without question or quibble sent me a replacement pump the very same day.. I fitted it about four weeks ago and it worked a treat.. for about four weeks .. two nights ago it died .. dead , nothing, not a splutter.. Yesterday I was talking to another RVer on the site and he also had to return a Shurflo Smart Sensor with exactly the same problems.. Now as luck would have it Linda emailed me today asking for details about the first pump's failure, regrettably I had to inform her about the failure of the replacement pump. :Sad: So, I want no more to do with Shurflo Smart Sensor, Linda has agreed to send me a Flojet as a replacement.. As always, Linda of Stateside Tuning has been great, no quibbles ..just great service.. :thumb: thanks Linda . shame about the 'not so smart' pump ..
