Hi @harris-k£b - we are experiencing an issue with the form on our website, however if you email or your details for marketing@altecnic.co.uk we can send you the calculators directly. Hope this helps!

Thanks for the feedback and for watching the video

The PRV controls pressure and regulates pressure/flow through it therefore passing water through/downstream of the valve to outlets. If you would like any more information on our PRVs, you can talk to our technical department by filling out the form: www.altecnic.co.uk/contact-us/. Hope that helps!

Hi @amandedhia unfortunately this is not something we control, but thank you for the feedback and watching our channel.

If it's anything like a vehicle thermostat it could be a wax which expands under heat. Wax motors are quite typical in these kinds of valves. An adjustment could just be a screw which adjusts where the body of that wax motor sits.

Thanks for your question! The operational function of the valve is to draw warmer water from the system to the cooler parts to prevent freezing, this would no doubt over a period of time draw water from within the property. The discharge rate is approx 0.5ltrs per hour at -5deg, however for the system to drop to 3deg at -1deg ambient temperature could take up to 36hrs so the chance of activation is minimal. Also if the valve were to activate, I would assume only an amount of the head of pressure will be released and not full system drainage.

@@altecniclimited947 thank you for such a complete answer. I finally understand its functioning.

Glad you like them! Thanks for the feedback!

Hi @yogeshmistry1662 - thanks for your question. Please email the details to technical@altecnic.co.uk who will be able to help you find the exact part you need and recommend a stockist. Thanks for watching!

Same question, did you get an answer?

@@Bulls79 nope.

@@tractortamno1 maybe I'll go with a standard mixer, to avoid any issues! 😄

Hi, no the flow rate is not significantly reduced, in fact the flow restriction in the tap will have more of an impact than the TMV

Thanks for showing interest in our products! There is a Caleffi North America, where you will have access to our range of Caleffi products, including the iStop® Anti-Freeze Valve. You can find out more using the link: www.caleffi.com/en-int/antifreeze-valve-108-caleffi-108601

@@altecniclimited947 thank you, but I still don’t see a way to actually make a purchase from that site. it seems all of the valves I’m finding for sale are in Europe.

Hi - thanks for watching! You can email sales@caleffi.com who will help you find a local stockist.

Awesome, thank you for your feedback and thanks for watching!

Hi Les, for all technical advice you can email technical@altecnic.co.uk or call us on 01785 218206. Thanks for watching and for your feedback.

Yes it of course matters if hot and cold are incorrectly connected

Thanks for your feedback and for watching! You may find our free, accredited, on demand training portal, Altecnic Academy of interest too. You can find training course details on our website at www.altecnic.co.uk/technical-hub/training-and-cpds/ - would love to get your feedback on this.

Thanks for your question Mark, we absolutely agree that choosing the right filter for the right system is key to ensuring an efficient working system for installers and homeowners. In the case of a heavily clogged system, a magnetic filter alone would not solve the problem and a full system flush would be required prior to installation of a filter like the XS. We also have a range of other magnetic filters with larger collection chambers that may be more suitable to larger systems. The benefit of installing the XS would be that the glass visual indicator allows installers and homeowners alike to visually inspect the cleanliness of a system without having to isolate and drain, meaning you only take action when it's required.

Hi - you need one on the flow and the return. Please get in touch with our technical team at technical@altecnic.co.uk if you would like any other info.

Hi @dorsetwatersofteners, you can now find the data sheet in the technical specification on the product page: www.altecnic.co.uk/drytraptundish

Thanks! - let us know what else you might like to see 😄

It is servicing or planned preventative maintenance he should of used. Also he forgot to mention to descale all parts including the strainers on each side. Also to record the incoming cold and hot water temperature going to the TMV’s and adjust the mixed temperature of required. You should also do a fail safe test which consists of isolating the cold and making sure the tap don’t run with just the hot coming out if so it will need replacing.

Hi Mate; COMMISSIONING OF THE VALVE Upon completion of the installation, the valve should be tested and commissioned as per the procedure outlined below or as specified by the local authority. The entire procedure should be read through thoroughly before the commissioning of the valve. A calibrated digital thermometer with rapid response time with maximum temperature hold, a small flat-bladed screwdriver, 3mm Allen key and the adjusting key (supplied with the Aquablend 1500) will be required to check and set the outlet mixed temperature of the valve. Ensure all outlets that will be serviced by the valve have adequate warning signs posted to ensure that no outlet is used during commissioning. Open the cold supply line to the valve, then open the hot supply line, ensuring there are no leaks. Open the outlet that is serviced by the shortest length of the pipe work between the mixing valve and outlet fixture. Allow the mixed outlet to flow for at least 60 seconds to allow the temperature to stabilise before taking a temperature reading at the outlet with a digital thermometer. The flow rate should be at least 2L/min. The flow rate can be checked with the aid of a known size container and a stopwatch, or Enware Flow-Cup (ATMS1201). The temperature should be taken at the closest outlet served by the thermostatic mixing valve. If the outlet temperature requires adjustment please follow the steps below. TEMPERATURE ADJUSTMENT 1. Using a small flat-bladed screwdriver, lever the Red Lock Shield (protective cover) off the valve. SEE IMAGE 5 (over page) 2. Loosen the temperature adjustment locking grub screw located on the hex of the top cap using 3mm Allen Key. SEE IMAGE 6 If the grub screw is not easily accessible, relocate the grub screw to the most accessible screw hole (3 screw holes are provided on the top cap for convenience). Leave the grub screw loose. 3. Fit the supplied key over the adjusting spindle. SEE IMAGE 7 • To increase the mixed outlet temperature, rotate the spindle anti-clockwise. • To decrease the mixed outlet temperature, rotate the spindle clockwise 4. Allow the mixed outlet temperature to stabilize for 60 seconds and once again take a temperature reading. Repeat the procedure until the desired temperature has been reached. 5. Tighten the temperature adjustment locking grub screw. SEE IMAGE 6 6. Push the top cover firmly back onto the top of the valve until it ‘snaps’ back into place. 7. Check the outlet temperature is stable over the full range of flow rates and that the flow rate is adequate for the application. 8. Close the outlet. 9. The mixing valve is now set and locked!
