Re: Water Pump and Water Tank Reply #25 – August 14, 2018, 12:38:30 pm It’s not a bad idea to occasionally drain the water tank and so easy to do with the drain valve.Larry 1 Likes
Re: Water Pump and Water Tank Reply #26 – August 14, 2018, 01:26:09 pm "I was hoping I wouldn't need to drain the hw, ... so it has to be drained."Hmmm! Guess the different floor plans are not the same in this regard. I have replaced my water pump three times and not once have I considered draining the hot water tank.
Re: Water Pump and Water Tank Reply #27 – August 14, 2018, 02:39:03 pm I think there is supposed to be a check valve to prevent the water heater from draining water back into the cold water plumbing, but they may not always work. With my rigs stiff water pipes and advanced age, I would rather just empty the tanks. I wouldn't use that clamp gizmo on anything but soft vinyl or newer rubber hose. RonB. 1 Likes
Re: Water Pump and Water Tank Reply #28 – August 14, 2018, 04:03:12 pm I got the pump installed (Shurflow 4008). It seams to pulse a lot when running only cold water and low flow. I am wondering if this will cause shower temperature to fluctuate on low flow. It runs smoother with hot or half hot so I am thinking it will be ok and will soon try it. I tried adjusting the pressure switch a 1/4 turn in either direction but that did not make much difference. Perhaps a break in thing? The instructions warn against adjusting the bypass if you are not a pro with proper tools

If you know how difficult it is to work on the water pump in a 30' IB you will not wonder that he was somewhat displeased, yet he got the job done, much to his credit. Give it a reasonable trial period and I think you will be able to live with it! 1 Likes
Re: Water Pump and Water Tank Reply #30 – August 14, 2018, 09:30:53 pm Good point. I should have thought of that since that is what our washing machine repair guy would do. Anyway, be sure to have two since you'll have to pinch both the in and the out hoses if you drain neither tank.

I hope it is at least as good as the model 2093 Whisper King it replaced. That one has worked well for almost four years since I put new rubber diaphragm in. I was able to stop the pump from cycling with low flow in the shower on the old one by increasing the pressure that turns it off. This minimizes the inevitable temperature fluctuations that go with reducing the flow. 1 Likes

Finding the sweet spot can take a bit of time and a few adjustments. 1 Likes
Re: Water Pump and Water Tank Reply #33 – August 19, 2018, 03:31:02 am Has anyone tried an accumulator? Not needed but they say it increases pump life.. I don’t care much but some folks may like less cycling (noise). I do like the idea of smoother flow. Hmmm... maybe I would like longer but less frequent pumping.
Re: Water Pump and Water Tank Reply #34 – August 19, 2018, 06:04:46 pm One is in our RV, put in likely by the original owner. It is an 89 and with pumps at that time it made a difference. The original pump was replaced at some point but the accumulator was left in place.I researched when we thought we might need a new pump (just needed cleaning) and the concensus seemed to be it is not needed with current pumps.One thing - it does take up a chunk of space. Ours is a cylinder about a foot across and 1 1/2' long.At some point we will test with and without it but right now I don't know if it makes any difference.Sent from Yahoo Mail for iPhone

Hmmm... maybe I would like longer but less frequent pumping. The old Whisper King pumps benefited from an accumulator.The Factory literature for the newer pumps, such as the 4008, tell not to use accumulators .So, having an old accumulator on hand, I had to try it with the new pump. The accumulator disrupts the pump's pressure switch and regulator. There is no improvement. The newer pumps need fiddling with the two control screws to run smoothly. Larry
Re: Water Pump and Water Tank Reply #36 – August 20, 2018, 12:32:18 pm I adjusted my bypass switch as well as adjusting the pressure switch some more yesterday and I’ve got it to stay on even with a pretty low flow. The flow is also smoother than it was. 1 Likes
