WEIL MCLAIN 97+ maintenance

new hot water boiler weil mclain ( wm97+high efficiency ) with hot water storage tank was installed about 2 years back and 3rd year running working just fine but i would like to know

does this really need servicing ?

if so, what really here requires servicing ??

how often do you do maintenance ( servicing ) - yearly ? every other year ??

if individual owner like me can service ( handyman with basic skills )
and if so, what precautions should be taken ? what exactly requires to be done ??

your help / guidance will be highly appreciated

psi guage reading is around 38 psi

very many thanks for your guidance
after going thru the maintenance instructions, i have noticed that reading
of pressure is around 38 and manual recommends it should be no more than 24
can you suggest how do i correct this please

also having hot water storage tank,
boiler is functioning all around the year ( not idle in summer )
so when the manual refers of before start of the season ( winter )
follow certain steps, in my case boiler is active at all times
may be lesser use in summer then winter for sure

there is not much of maintenance that suggested
except pressure release valve and all other are more of observation

any suggestion here ?

thanking you

Something is wrong.. either the gauge is off hopefully, or you have other issues..

The relief valve should trip at about 30 psi.. So if your at 38 and it has not tripped then that can be dangerous.

Either your fill valve is putting too much water in the boiler or the expansion tank needs servicing...

psi guage reading is around 38

how do i know my psi guage is working ?

i dont see much movement on this guage - study around 38 psi
not sure what other two needles meant for ( in all 3 needles in this guage )

so any way i can see if this guage working well ?

also i have not operated any of the valves since it was installed about 2 winters back ( 3 rd running )

what should i do to test these valves ? how often do you check them ??

picture of the guage is enclosed herewith and will appreciate your guidance from here

You would need to take more pics from afar, and different angles and well lit...

You are reading the gauge wrong.. My old eyes show about 18 psi... Thats fine if so..

The bottom gauge is the temperature... That varies but should not go higher then about 180f during the cold months..

The red indicator is just a dial you can set for a reference point I usually put that dial at 30 psi.. So at a quick glance you can tell if the pressure is too high...

Again psi is the inside scale. The outside scale is H2O ft I think.

I dont touch the relief valves to test... I change them every 5 years or so.. Testing them they often leak so replacement may be eminent then...

boiler - psi reading

yes, you are correct
it was my mistake in reading
now i have realized
thank you very much for correcting me / how to read the meter
little bit confusing as it has h20/psi/farenhite/centrigrade

?? any suggestion as to servicing this boilers - not much in the manual
except inspection of few things which i can do !!

as to pressure release valve / noted and i am with you
have not touched it since it was installed - this is 3rd year running
so i have 2 more years to go before replacing

similar pressure release valve on indirect hot water tank
do i need to replace that too ?

? in one of the bathroom sink when i start hot water upto certain level it goes fine but when i open it more (close to full ), it starts rattling noise and then i blend some cold water to it ( mixing valve - hot and cold separate ) noise goes away or lower the flow of hot water by reversing then noise goes away

can you suggest me what is wrong here ? something with my sink faucet ( which is about 2 years old from MOEN ) and how do i correct it ??

once again, thank you for your help / guidance & support
