Recent Expansion Tank questions

A friend and I replaced my home water heater 14 months ago.

A friend and I replaced my home water heater 14 months ago. We used shark bite hoses to make the connections. we did not reinstall the shut off valve nor did we install an expansion tank. Everything has been fine during this time.This past week whenever we flush a toilet, run the shower, dishwasher etc. there is a sound created by what sounds like a pressure issue. i need to know what this is and how to correct it. Is it dangerous to keep using our system until it is repaired?

I have a basi Rica combi boiler system, recently the pressure relief valve began leaking about a quart or so a day. I replaced the valve, but get the same results? I was told I may need to add an expansion tank, I would have thought that would be internal to the system if it's required?

I have an oil fired hot water furnace with tankless water

I have an oil fired hot water furnace with tankless water heater. It is about 17 years old. About 4 years ago I replaced the pressure relief valve on the back of it (30 PSI) because it was leaking a bit. Recently the new valve starting leaking a lot on and off. I let the furnace cool overnight. I just replaced it the valve. I turned everything back on and watched the furnace heat up. The valve started leaking a lot - I noticed the pressure gauge on the furnace climb straight up to 30PSI. It's usually around 18PSI but I'm guessing it's been getting to 30 regularly and filling a coffee can every couple of days. What could be causing the pressure to climb to 30?The control box is set to 160/180 F with a 0 differential.

Our heating personnel shut the water valve going into the

Our heating personnel shut the water valve going into the boiler and explained that the valve should be replaced when they come to service it again later this year (December 2016). My questions: a) Will this injure the boiler? The temperature gauge goes up to 185 Degrees F, yet the pressure remains steady at 15. b) Will the efficiency of the boiler be compromised by maintaining such a lower pressure. Thank you.

I own a viallant GA100-10 SPVD and there's a pipe on the back that I think is an overflow or release valve. Anyway, it's dripping water a lot. I had the valve replaced but it's still dripping. Is this a pressure issue and how do I get it to stop leaking. It's hot water coming out. Thank you

Where is the best location to install an external expansion

Where is the best location for me to install an external expansion tank for my closed heating loop of my Baxi Luna 310 FI?Is it best on the return side main, back to the Baxi just after the zone valves? Or after the internal pump on the pressure side feeding the upstairs radiators?2+ bars of Pressure when unit is running for heating system, internal expansion is either shot or I believe not adequate for systems application. Pressure is fine at just above 1 bar for DHW.
