Water filter flow rates.... - Page 2

That probably will cover it. according to the site, the maximum drawdown is 0.7 gallons. I assume that means that it can deliver 0.7 gallons before losing pressure. That number may well be a little higher given that the line itself has nearly adequate flow.

The Elektra Sixties A3/T1 boiler is 6L, and I would guess that it's probably only filled with about a gallon of water. Since you're never going to empty it all the way in normal usage, you should be safe. Just make sure you have an adapter to connect that to your setup between the filter and the pump. depending on what your pressure regulator is set to, you may decide to put it before or after the pressure regulator. In determining that, you want to make sure you get even inlet pressure to the pump during brewing. If it flutters during boiler fill, that won't matter.

My house pressure is 60psi and my regulator is set at 30psi. I'm thinking it may be better to put it before the regulator. Any opinions?

I would say so. However, you may want to consider re-calibrating your setup for 20PSI on the regulator, or getting a tank set at 30+ PSI. This one is in the same price range, but it's set at 40 psi and has a 1/4" M NPT threading, so it would be easier to find yourself a John Guest adapter (if you're using that system).

The Lowe's tank is adjustable to whatever psi you want. It has an air valve so you can keep the valve at 60psi and for me, would give maximum usage from the tank. Also the Lowe's tank is readily available. I'm going to hook up a ball valve to the tank so the fitting type isn't really a huge issue, not to mention I have a $10 off coupon :)

Hi,
I realized after owning my Elektra T1 for a while that the filter supplied only .75gpm. This is OK if only brewing but on boiler refills the pump made a buzzing noise. I went to Lowes and bought a 7 gallon diaphragm tank (don't need that big but it was the smallest tank that came with a mount) and hooked it up after the filter/softener but before the regulator. I set the pressure around 30psi and turned on the water.

The machine is much quieter and the boiler refills are much faster with the pump running much less. Great investment. I just wish I knew about it before................

Thanks for all the advice.

Joe

Hey Joe, glad you like your accumulator. I installed mine last night, to cap off my Elektra pump outboarding. You can check it out here if you want. I had to install mine after the regulator, as for some reason my regulator seems to add drag to the inlet. :roll:

I was debating to go before/sfter the regulator too. Anyone know what the flow rate for Chris' Coffe regulator is?

I'd like to know too, but I judged by the pressure drop I got across the line, and the noise the pump made. If yours is quiet, it's probably safe, and I am only left to wonder what could be wrong with mine... :roll: Alas, it doesn't matter. The accumulator acts as a very strong pressure stabilizer. I think it's fine on either side, given that the pump is OK during boiler fill.
