    2 appliance waste flow

    Hi, looking to fit a sink, with a dishwasher located next to it and a washing machine about 1.5m along. I was thinking of teeing off the one waste pipe and sticking a stand pipe with trap on for both the dishwasher and one for the washing machine. Would this be preferable or should I just use...

    Shower flow rate

    In summer months do you get a better flow rate from electric showers as the water may come to shower a few degrees warmer??

    Changing taps - can't work out the cold flow set up

    Hi, I am a DIY plumber and was going to change the mixer tap in the utility room (the old kitchen from the 70's) and I am puzzled by the cold flow. On the image starting from the pipes in on the bottom of the cabinet. On the left is hot, on the right is cold. The cold services the tap and the...

    Gate Valve on CH Flow/Return Loop

    I’ve recently moved into a bungalow with an open vented central heating system installed in 1987 with 8mm microbore running to the 10 radiators. One of the radiators needs replacing as it’s got a small corrosion pinhole in the body and we wanted to fit a larger towel rail anyway. Having gone...

    Flow restrictor?

    Hi I was having an issue with my outside tap, where if I turned it on too far the pressure and flow would suddenly be reduced to a trickle. Replacing the tap didn't make any difference. I've found where the pipe joins the cold water feed, and just after the isolation valve, there's another...

    water pressure and flow..what's the ideal combination

    Water pressure static is 8bar. Working pressure (if that's the term) is 6bar. Flow rate from cold water is 28-29L/min. Now this seems good (to me) but reading some suggested figures for ratings at different outlets, my readings seem almost dangerous by comparison. What should I be aiming for to...

    UVHWC with low flow and pressure?

    What would be the lowest flow and pressure you would fit an unvented cylinder onto? Just doing a quote for a house with a bathroom, en-suite, WC and kitchen so not ideal for a combi. 2.5 bar standing, 2 bar with taps open 16LPM 25mm blue poly incoming main. Currently got a heat only with OV...

    Priority cold water flow to combi

    I understand that its normal for output flow from a combi to reduce when the inlet cold water flow is reduced (when other outlets are opened) but is there a method/process/configuration that can be adopted to minimise the effect in the the drop in flow and in doing so, provide a priority flow...

    Do I have an overly demanding flow switch(?) on boiler?

    Caveat: I don't do boilers so no idea about them. My flow switch comment is pure guesswork based on zero understanding. If I turn my kitchen mixer tap on hot, fully on, cold fully off, about 75% of the time the combi fires up and produces hot water for a bit but will then cut out. I am not...

    Having trouble finding duel flow kitchen taps

    There seems to be a big shortage of duel flow kitchen taps, I know the trend is towards combis but there is still a lot of flats/bungalows with poor hot water pressure which means you need a duel flow tap. Any one got a good supplier of them? Thanks

    DPS Thermal Store- hot water/flow issues

    Hello, hope you're all enjoying the bank holiday weekend. I have a customer with a Dedicated Pressure System (DPS) Heat Bank System (Thermal Store). If they run one bath/shower, it's fine. If they try to run two at once the water at both is barely even warm. I know the house has been extended...

    Can water flow rate be measured at the supply pipework?

    Hello Guys I recently posted a thread about low water pressure at taps in a new kitchen installed by a company using sub-contractors. I have 0.44 bar of hot water pressure and am getting a flow rate of 4.5 Lpm at the new hot monobloc. The Blanco people say that the taps are rated at minimum 0.3...

    Flow rate new kitchen install.

    Hello again Guys I've just had a new kitchen install. The fitters tapped into the overhead 15mm hot and cold that feeds the Utility Room 3.0m further on. The hot flow rate in the Utility Room (Monobloc taps) is 9.5 litres/min. In the new kitchen monobloc the flow rate is 4.5 litres/min, less...

    Cold tap in upstairs bathroom flow problem

    Hi all, I'm having an issue with the cold tap in my upstairs bathroom. There is barely a trickle of water coming out, while the hot water tap is running fine. I'm not having any problems with any other cold taps in my house. A Google search suggests that there may be an airlock in the system...

    Hi flow radiator valves for 1 pipe systems

    Hi Can anyone recommend a decent locksheild valve to pair with the Danfoss RA-G TRV? The RA-g is high flow but I can find a matching locksheild to suit on their site. Cheers
