The 60 PSI version is intended for systems that require stronger pressure and whose plumbing components are rated accordingly.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eDoes the 60 PSI model give more flow than the 40 PSI version?\u003c\/h3\u003e\n\u003cp\u003eThe specification provided for this model lists up to 15.2LPM. The main difference highlighted between the two versions is pressure capability rather than nominal maximum flow.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWhen should I choose the 60 PSI version?\u003c\/h3\u003e\n\u003cp\u003eChoose the 60 PSI version where stronger system pressure is specifically required and every component in the fresh water system is capable of safely handling it. If your system is designed around lower pressure, the 40 PSI version may be a better match.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eIs 60 PSI too high for a caravan?\u003c\/h3\u003e\n\u003cp\u003eIt can be for some caravan plumbing and appliances. Check the pressure ratings of the hoses, filters, taps, mixers, water heater and fittings before installing this model.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCould I need a pressure regulator?\u003c\/h3\u003e\n\u003cp\u003eYes, potentially. If part of your system has a lower maximum pressure rating than the pump's 60 PSI cut-out, an appropriately designed pressure-control solution may be required.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eIs this a good pump for a large caravan with several fixtures?\u003c\/h3\u003e\n\u003cp\u003eYes. The PAR-MAX 4 HD is designed to supply up to four 12mm outlets and offers enough total flow for larger multi-fixture systems.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan it run four outlets at once?\u003c\/h3\u003e\n\u003cp\u003eJabsco specifies support for up to four outlets. The 15.2LPM total pump flow is shared between whichever fixtures are operating, so performance depends on the demand of each outlet.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWould this run two showers at the same time?\u003c\/h3\u003e\n\u003cp\u003ePotentially, especially with water-efficient shower heads. The combined fixture demand needs to remain within the pump's available flow after plumbing restrictions are taken into account.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWill I actually get 15.2LPM from one shower?\u003c\/h3\u003e\n\u003cp\u003eNot necessarily. Maximum pump flow is reduced once the pump works against pressure, hose restrictions, filters and the shower head.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eHow does this compare with the PAR-MAX 3 HD?\u003c\/h3\u003e\n\u003cp\u003eThe PAR-MAX 3 HD provides up to 11.3LPM and is designed for up to three outlets. The PAR-MAX 4 HD increases maximum flow to 15.2LPM and supports up to four outlets, making it better suited to larger systems and simultaneous demand.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eWill the 60 PSI model improve shower pressure?\u003c\/h3\u003e\n\u003cp\u003eIt provides a higher system pressure capability, which may improve performance where the plumbing and shower equipment can take advantage of it. The final shower result still depends on the shower head, water heater and restrictions.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan I use it with a caravan hot-water service?\u003c\/h3\u003e\n\u003cp\u003ePotentially, but this is one of the most important checks with the 60 PSI model. Confirm the hot-water system's maximum inlet pressure before connection.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eDoes the pump turn on automatically?\u003c\/h3\u003e\n\u003cp\u003eYes.

Keep the inlet plumbing airtight and minimise restrictions.\u003c\/p\u003e\n\u003ch3 style=\"color: #00aaff;\"\u003eCan it be installed vertically?\u003c\/h3\u003e\n\u003cp\u003eYes.
