Get the engineer at the supply house to help run a load analysis. They have the software.

You'll need to be the feet on the ground, and get the pipe sizing and the specs on all equipment on that branch coming off the main.

This crap happens all the time in electrical, when someone "wants to add a circuit". In electric, you have a breaker that will trip.

With water, you get damaged parts as your "breaker".

Enlighten me on a couple of topics;

Why are you running water through a boiler, when the boiler is not engaged in the process?

Why is condensation a problem while the boiler is in service, but not a problem when it is idle but with water flow?

With two boilers in service at the same time, might it be possible that one of them is "hogging the load" (waterflow) (NPSH), encouraging the other to be starved (low NPSH)? This being my reason for asking about multi-boiler operation.

A 2 1/2 pump assembly was ordered Thursday afternoon. The situation was explained to the best of my ability to the shot callers (mostly me?) based on the info I have gleaned from you people..
I was off Friday and the weekend. So I have severed ties with this situation till Monday.

Until then I am spending my time making this abomination to kick my nieces and nephews asses in the Easter hat making contest..
Try to control yourselves, especially you Kingston!

Bossman.. as was mentioned the pumps on the boilers run 24/7 even this both boilers do not.
That is the stainless impeller on the pump assembly that has to date, not caused problems

Just talking here, but the stainless impeller is holding up better than the bronze one, which was destroyed

Chicken or the egg scenario but it seems likely cavitation first caused bronze impeller failure which then accelerated pipe failure downstream, make sense?

Conversely the stainless impeller is holding up better against what is most likely the same cavitation issues therefore not multiplying the effects downstream

Obviously some assumptions being made there but just a thought

SC I do not have a good answer for you as to why the pumps run 24/7...
the condensation I mentioned was from cold pool water (80) entering the boiler tubes and being heated to 150-170..

That condensation caused premature failure of combustion chamber

It was pointed out a mixing valve was needed to temper that water entering the boiler so now it enters at approximately 130

Beav needs hat.

$100 if you include bronze impeller.


Screw you! I'm voting for Trump again!

It’s well established that all Californians are wealthy real estate tycoons.

You mentioned 6 separate boiler/pump systems,

Their all built identical, or this one is the lone one built in this configuration?

Box office earnings have been slow.

Trailer repairs high.

Beav will have to build his own hat.

Kenneth..we have 5 highs schools with this the only dual boiler situation. One has a brand new pool and I have not even been into the boiler room there yet so 6 pool boilers total but one unknown.

Those 5 pool boilers are RBI dominator with same FDE mixing valve and BG pump. I posted a picture earlier of another system that uses the same parts and design but the layout is different due simply to existing pool lines

To further add confusion there are 2 more of these “packages” but for domestic water heating. As they don’t deal with pool water we can probably leave those out.

I guess that’s a long winded way of saying while the packages are the same, the situations they are plumbed into, are not.

Hey! You said you weren’t going to shop my bid.
I guess I can understand it, since Kingston is Campfire Psyops royalty.
I’m tapping out on this one. I bid as much as I could afford. Obviously I should have stayed on the porch. 😉😁😂

You've seen Beav's stock painting? Lord help us.

Certifiable's price seemed outrageous until I realized he didn't have to come on here asking for help making it.

I think theres a plumber in the Etsÿ pile, if you catch my meaning... The man has obviously amateur modeled hats before.

Renegade will be on here momentarily with a forensic analysis of the 'fashion' photography. It's no coincidence that the bottom of the frame stops just above the nipple line.

I'll set a Gofundme up so we can get Beaver a proper hat.
