groco pressure tank installation

cruisingmom · #1 (**permalink**) 07-07-2010

Hello All
I just purchased a Groco 1 gallon pressure tank on E-bay which came with no instructions. My guess is I just install in with a t fitting into my existing water system after the par pump and that's all that is required. However I am looking for advice as to whether I need to do anything else - could it really be that simple? Thanks for the reality check

Are you talking about an accumulator tank?? Yes, it is that simple.

Yes - this is an accumulator tank - 1 gallon capacity. I was trying to relate this to the accumulator tank on my well. But the well tank has the pressure gauge and the electronic pump switch. I was thinking that if I hook up the Groco after my par water pump it is just an in-line connection without any additional gauges or hardware - just an in-line accumulator. Do I have this correct?
Thanks
Andy

Yes, all the Groco tank does is sit in line with the pressure pump and IIRC has a membrane in it to help stabilize the pressure in the water system and reduce the pump cycling.

My boat had one in it when I bought it 13 years ago. My water system worked OK, so I never messed with it. A few weeks ago I was having a problem, so I checked the tank. Turns out it has a air valve on top that looks like a tire valve. I went on Grocos' site, and they said to check the pressure regularly with a tire pressure guage for 28-30 lbs. Mine was 8-10, so I pumped it up with a bicycle pump.
I don't know why they don't include this in their instructions, but its on their website.
