    Can I fit a modern radiator to a gravity fed radiator?

    Evening All, I turned up to change a radiator last week only to find an ancient rad connected to a big old steel one pipe system with no return. Is it possible to connect a modern rad and valves? Would I need to pipe it top to bottom? There's copper tails coming off the steel pipe tees. Thanks...

    Possible Leaking Gravity Fed Hot Water Cylinder Valve

    Hi all. This ‘valve’ is at the bottom of our domestic hot water cylinder. Anyone have any idea what it is please? It must’ve been there for many years and seems to be leaking.

    Gravity fed system not sure how this valve works

    This valve is fitted to the lower heating coil of the hot water cylinder Can anyone say what is the point of it I have been told its a thermostatic valve to control hot water temp so would have thought it may be in the wrong position ?Any explanations welcome

    Taking forever to pressurise gravity fed system. Why is this?

    Hello, I live in a two floor semi with a gravity fed conventional gas fired boiler (Potterton Kingfisher MF). The boiler is fed cold water from the loft water reservoir tank (which also feeds the cold water taps in the bathroom & the WC cistern). There is an expansion vessel attached to this...

    Gravity or mains shower?

    I have a dead 1990s Triton T70 shower and, for purposes of replacement, I'd like to know if it's mains or gravity fed. As it won't even switch on, I cannot get any water out of it so I can't just switch off water at mains and see if water still flows from the shower. I note that current Triton...

    Wood Burner back boiler with gravity rad system.

    Hi All...thx for the help in advance. I have recently installed a wood burner with back boiler heating system. Set up with gravity rad and header tank in loft. I have a recirculation pump installed that I have connected to the rad system that I turn on and off manually. I wanted to know how...

    Using combi fed and gravity fed showers simultaneously

    Hi all, I have a combi boiler for hot water and heating but have 2 showers in the house. Obviously low water pressure if both showers are used at same time. I'm wondering if I could install a water tank to gravity feed one of the showers, with new electrric shower and if so how to stop the water...

    Blended hot outside tap from gravity

    Customer wants an outside tap for dog washing so needs to be blended. The hot water is gravity and its a bungalow so little head at the point of installation. I can't get a cold from the storage cistern to the utility so it has to be mains cold. Can pressure reducing valves be taken down to...

    Gravity Fed system in Bungalow with two Automatic Air Vents

    Hi, I’m replacing my old Honeywell Smartfit system on a oil fired gravity-fed system in a bungalow. I’ve read conflicting advice on gravity fed systems requiring an AAV, unless in a bungalow to aid bleeding on first fill? One AAV is in the loft on - what I think - is the boiler return pipe...

    Tap for a gravity based hot water system

    Hi, I have a gravity based hot water system, and recently had a new kitchen installed. We never had a noticeable hot water pressure issue before, but the flow from the new tap is down to a trickle. Pressure head is c.3m. Flow is 2L/min compared to 12L/min minute out of the hot water tap...

    Thermostatic Mixer shower can be fitted to Mains and Gravity Hot?

    Hi all, I've been researching and planning a job for my home the past few days and a few pieces of advice would be welcome to help me along the way. I have a cloakroom toilet which has a toilet and a sink, where the sink currently is there is good room to put a small shower cubicle and a...

    Urgent advice - Replacing gravity water system

    We need an urgent advice, we have a gravity water system and we are in a middle of loft conversion. We are adding an en-suit in loft and prefer to have a good water pressure there. What we want, is to either be able to run multiple showers at once, or if one person is having a shower, other...

    Why is there a blue and a red float for a FOP on a gravity fed tank?

    I assumed that the red ball float was for a header tank on the central heating side and the blue ball float was on a cold water storage tank. I thought the reason for this was only to help identify the tank but after finding a lot of cold water storage tanks with a red float, I must be wrong...

    Gravity feed hot water tank

    I’m fitting a ‘gravity feed’ hot water tank in a mobile home that has restricted head height for a cold gravity feed header tank. I can install an expansion over flow to an outside drain. Is it possible to use a Pressure Reducing Valve to supply the cold water from the mains supply. Or is there...

    Installing decent pressure shower on a gravity fed system

    We currently have an electric shower fed with mains cold this mains cold is really bad pressure coming into the shower resulting in really poor pressure from electric shower. We have a gravity fed system what's the best and cheapest way to get a decent pressured shower fed from our gravity fed...

    Do NRV's reduce flow on gravity and/or need minimum pressure to work?

    Fitted a mixer tap and the mains forces it's way back up gravity hot. But the hot pressure is already very poor due to it being a flat with a combination cylinder on the same floor level as the tap. Carefully chose one that looked fairly modern (as customer wanted) but had good flow on low...

    Greywater Gravity Drain Problems

    Hey guys, I live in Arizona where it is hot as blazes and water is scarce. I made a DIY gravity drain system to reuse water from my washing machine to water my trees. Below is a really well-drawn sketch (haha) of the setup. My problem is that little to no water comes out at the tree! I already...
