Re: Oil Tank
@LDR as far as the Fill and vent pipes they can both be 1 1/4, or 1 1/2 or 2" but they have to be the same size.
In some locations in the old days the fill was 2" and the vent 1 1/4" but they changed that many years ago.
Re: Oil Tank
Any second hand tank will have problems since there have been tank bottom deposits building up from the first delivery all the way to the last delivery. How old is the tank? What is the condition of the outer steel tank? Is there stuff other than oil in the bottom of the tank?
The thing about steel tanks is that they rot and rust away from the inside as well as from the outside, so you really can't tell the condition without expensive testing which makes a new tank less expensive than testing an old tank. With the plastic inner liner of the Roth tank I would feel more comfortable with using that for a good long time if it is in good condition.
I would just take the time to thoroughly clean the junk out of the bottom of that tank. That would involve about 40 gallons of clean oil and a pump with a garden hose spray nozzle on the end of the pump’s discharge hose. Then I would take 10 gallons of oil and wash the bottom like I was spraying off the driveway with your garden hose. After that was done I then empty that oil and take 10 gallons of clean oil and repeat. Then another 10 gallons and repeat. By the time you get to 40 gallons you should have a clean tank. You need to suck out as much of the dirty oil from the tank as you can each time before adding clean oil for the nest wash.
The Roth Tank has special fittings on the top and they convert to standard 2” pipe thread for easy connecting to the fill and vent pipe, vent alarm and the top feed fittings.
Other than that, you just make sure it is on a flat level surface in your basement and install it like you would install an oil tank according to the code. It is a tank full of combustible liquid in your basement, you know. Do it right or don't do it at all.
Re: Odd situation
The black feeder/low water cutoff is a McDonnell Miller #51.
Both the feeder and the lo water cut off switch are operated bu a float (like in a toilet tank). Those controls need to be cleaned and flushed every so often. Probably needs servicing.

That's….. What I said
Except for the separation thing, which can't happen.

Re: Lochinvar boiler isn’t keeping up
Hi, One big and one small reason not to oversize storage. The small one is more heat loss/waste from the greater surface area of the bigger tank/s. The big one is the tank can become an amplifier for bacteria if the volume of the tank is not turned over pretty consistently. The bacteria then gets inhaled in the shower or elsewhere, and nobody is happy.
Yours, Larry
Re: Lochinvar boiler isn’t keeping up
I'd still prefer to know how a system is controlled and piped prior to changing it out for a bigger tank I think.

Re: Lochinvar boiler isn’t keeping up
you really think a 40 gallon boiler mate with an 80k boiler is a 1 bathroom tank? I have a 50 gallon low efficient gas w/h with a 50k burner and run 3 showers simultaneously when the family comes up, one of those showers has 3 people use it one after the other and we don't run out. If all the OP was having issues with was regarding their tub I'd say its definitely too small, but they also said if they run 2 showers at the same time they run out. If these are somewhat standard showers then they have a piping or control problem in my opinion, the tub might still not be able to go at the same time as the showers though.

Re: Munchkin 140m troubleshooting FO9
Thanks Bob. You are always so helpful.
I'll look at the website, didn't think there was one since they were supposed to be out of business.

Re: Furnace stack temp
Is that 550 gross or net? If the space is 65 and the 550 is gross your net is 485 which isn't to bad. Other than that I would consider 550 a little high.
What fan speed are you running? 125-135 is a bit high on the discharge. Your temp rise is 65 maybe check the manual and speed up the fan.
Re: Drain radiator in one pipe system
As far as I know the radiators here (one pipe system) have not been drained in almost 100 years.
If you think there is excessive trapped water maybe the radiator valves are not opened all the way, broken or the pipe pitch is incorrect so water in the pipes near the radiators is trapped and puddling.
If you do drain the water from the radiators and don't repair the underlying cause it will simply return after a heating cycle or two.
